Our take on the Audioengine W3

The Audioengine W3 lets you make a convenient wireless connection between any two components where you'd normally use a stereo RCA or mini patch cable. This two-part system includes a powerful wireless Sender and a companion Receiver. Connect the Sender to your portable music player via the included stereo minijack cable, or plug it into your computer's USB port. Then connect the Receiver's stereo minijack output to your audio system or powered speakers.

Send wireless audio to your sound system

The Audioengine W3 lets you make a convenient wireless connection between any two components where you'd normally use a stereo RCA or mini patch cable. This two-part system includes a powerful wireless Sender and a companion Receiver. Connect the Sender to your portable music player via the included stereo minijack cable, or plug it into your computer's USB port. Then connect the Receiver's stereo minijack output to your audio system or powered speakers.

Powered by USB — one adapter included

Both the Sender and Receiver are powered via their USB connections. One AC-to-USB power adapter is included in the package. This is perfect when you're using the system to send audio from your computer, because the Sender can get its power from the USB port. It's also perfect when using the system to wirelessly connect your music source to the Audioengine A5+ powered speakers, which feature a handy back-panel USB power output. Other AC-to-USB power adapters — such as the one that comes with most iPods® — can be used for applications where you need two adapters.

Unparalleled sound quality and versatility

The W3 can pass CD-quality sound with no loss in audio fidelity, so you can enjoy your music in full detail — just like you would with a wired connection. The transmitter has an effective range of 100 feet, so you'll get a strong signal not only across the room, but across your home as well. And this versatile system can also be used in other applications. For example, pair the W3 and your compatible home theater receiver with Audioengine's A2+ compact powered speakers to make a wireless rear speaker setup for your surround sound system. Or use it to create a wireless subwoofer. With the W3 Sender's ability to transmit to multiple receivers, you can even have multiple subwoofers to add more boom to your room.

I had an old Linksys Music Bridge. It worked okay, but the software that came with it wasn't very reliable or easy to troubleshoot. These are great. No software to configure; truly plug and pay. Sound fidelity is excellent. No problems with audio cutting in and out like my Music Bridge.

no delay wireless

Jonathan from Gorham, ME on 9/17/2018

Crutchfield Customer Review (What's this?)

I'm using the W3 to have sound from my laptop go through my aging NAD receiver amp. I'm using this because a wireless Bluetooth connection was not fast enough for video and sound to sync. The W3 uses actual WIFI so there is no sound delay when I'm watching video on my laptop. It was simple to connect. I opened the box plugged in the receiving dongle into the RCA in jack on my NAD and then plugged the USB sender into my computer. Once the sender and receiver were synced I simply changed my output device settings on my computer to go through the W3 rather than internal speakers and I had fantastic sound with no delay.

Pros: small, easy to connect, no wires, no delay between computer and stereo so watching video wirelessly is possible, uses it's own WIFI NOT bluetooth as a connection.

Cons: receiver end needs a power source when not plugged into a USB

Crutchfield customer from Fort Wayne, IN on 9/8/2018

Crutchfield Customer Review (What's this?)

Works great! Hooked up old amp with new amp. Now my shop rocks now. For how small it is it works. Well worth the money.


Cons: Wish it had a another power supply

Super easy install, but be aware of potential

Crutchfield customer from Avon, OH on 7/30/2018

Crutchfield Customer Review (What's this?)

Super easy install, but be aware of potential interference from both solid objects to wireless (microwave, wifi routers, etc). The signal only has to go 15-18 feet, but through the AV cabinet and outside wall. I used a USB extender to place against the AV wall and 3 feet closer to the source. Works great.

Pros: -Super easy install -No configuration/pairing needed (if using 1 source)

Cons: -Wireless signal seems more prone to interference -Walls/objects shorten effective range


MJ from Nicholasville, KY on 7/9/2018

Crutchfield Customer Review (What's this?)

I am thrilled that this works with my new Onkyo receiver. Moved into a home with separate home downstairs TV surround sound and upstairs in-wall speaker surround sound systems. With the help of the awesome customer service department, I was able to easily utilize the downstairs receiver in the whole house. Yay! Super easy to put together with their help!

Pros: able to use the system built into the home

Cons: NONE!

chris j from Greenville, SC on 4/2/2018

Crutchfield Customer Review (What's this?)

Sound cuts out constantly. I even removed any routers or potential devices that cause interference.

Pros: sounds good when they work

Cons: sensitive to interference.

Up and Running in 5 minutes

jerry from Seabeck, WA on 6/7/2017

Crutchfield Customer Review (What's this?)

Described to Hogan at Crutchfield exactly what I was trying to accomplish. He spec'd these out and actually put everything I needed in a shopping cart and all I had to do was checkout. When it all arrived, setup was 5 minutes and I was enjoying digital quality music transmitted from my cable tv box to my NAD integrated amp with excellent CD quality.

Pros: Works as advertised, easy setup, excellent sound quality, negated the need for long wires stretched between rooms.

Cons: none so far

Audioengine W3

E from Mount Juliet, TN on 3/11/2017

Crutchfield Customer Review (What's this?)

We use this with headphones for listening privately to TV (so our spouse can sleep). I previous wrote a review that there was a continuous loud hum, but I discovered that the sheath covering the wires was split, exposing the wires. Crutchfield immediately replaced the unit, and now it works perfectly with no interference at all. Thank you, Crutchfield, for your consistent customer service!



Audioengine W3: cuts out a lot, regardless of my tests

Nat from St Petersburg, FL on 2/2/2017

Crutchfield Customer Review (What's this?)

They work, BUT: I have tried two different sets of Tx & Receivers I have used both the cables that come with them and my own, including transformers. I have tried using multiple sources of sound (TV, Computer, Stereo) I have tried multiple receivers of sound (2xreceivers, 2xhead sets & TV) I did all of this as a test to insure it was not my use of them (I was hoping it was "me" I have tried locating them in different environments within the house, including keeping them 2-3 feet from each other (transmitter & receiver), 20ft, 50 ft and almost 100ft) I did this to test them and no matter what I did: Both sets intermittently cut out and produce silence a lot during all broadcasts. Since I ordered a replacement and got the same results, I have to concur that it is the devices and not my use of them. I called tech support just to make sure there was no secrete I didn't know about and they told me that I have done everything they would have thought of- and no secrete. It one point, there was a buzz/hum that I eliminated by moving the transmitter to a new location/power source, then I discovered this new problem.

Pros: if one can live with the sound intermittently cutting out, then they are good

Cons: even replacement set cuts off sound intermittently, regardless of sound source or detonation Can produce an ever present buzz/hum if in a bad location (transmitter) - takes some testing to find good location from transmitter

Audioengine W3 works great

William from Aiken, SC on 1/3/2017

Crutchfield Customer Review (What's this?)

I am using it to send output from one integrated amp with a network player to the input on a home theater receiver in another part of the house about 60' away. Easy plug and play installation. Much, much easier than running 60' of shielded cable between the 2 amplifiers. Instant, automatic pairing. Frequency range seems to be as good as I can hear (at least 44khz CD quality). No static, interference or drop out. No latency that I can audibly detect. A bit pricey and only come with one power supply. I used an old iPhone power supply with USB cable for the second unit. I worry about life expectancy since they can't be turned off without unplugging them.

Pros: Range, sonic quality, low latency, plug and play.

Cons: Price seems high but quality costs.

Works great; much better than my old Linksys Music Bridge

JCinFrederick from frederick, MD on 3/12/2016

Crutchfield Customer Review (What's this?)

I had an old Linksys Music Bridge. It worked okay, but the software that came with it wasn't very reliable or easy to troubleshoot. These are great. No software to configure; truly plug and pay. Sound fidelity is excellent. No problems with audio cutting in and out like my Music Bridge.

Pros: -plug and play -good fidelity -no problems with audio cutting in and out

Cons: Audio cables are a little short, so you may need to buy a longer audio cable, depending on the location of you equipment, relative to your electrical outlet.

Neat Little Devices

W Ledford from Georgia on 12/13/2015

Crutchfield Customer Review (What's this?)

I have just completed my install and these neat little devices make it possible for me to extend the Onkyo main unit to have a Zone 3. They are very easy to install, no programing, just plug and play and they seem to work well.

Pros: Easy install

Cons: None

Audioengine Rocked It!

Chris G from Illinois on 9/13/2015

Crutchfield Customer Review (What's this?)

I had a couple of issues at first but it turned out to be with my receiver - not the Audioengine. It really works as easy as it says it does. I am using it to play music to the speakers on my patio using music stored on my laptop via the Denon receiver that is connected to my home network. The only problem turned out is that my laptop battery did not last long enough! Support from Crutchfield was awesome. They are very patient and helped me through. Thank you!



Audioengine W3

hy from Staunton, Virginia on 9/2/2015

I had figured out how to send music (CD, tape, vinyl) from my stereo system to my computer for listening and ripping, but really wanted to send music from my computer to my stereo system. Finally a product came along that promised to do this, and the Audioengine W3 came through. Now I can listen to my computer's digital music through the four speakers connected to my computer AND the four speakers connected to my stereo system. Excellent! The setup wasn't as easy as I had hoped, but with some help from Crutchfield tech support, I figured it out. (See below for the problems I encountered.)

Pros: The Audioengine W3 is a very simple adapter that works as advertised and actually improved the sound of my digital music files.

Cons: The setup guide was confusing as to configuring the computer-to-stereo system link. Whereas the guide said to "Connect an RCA cable (not included) from your stereo receiver's RCA inputs to the RCA "Y" adapter," the included "Y" adapter can actually be plugged directly into the receiver's jacks. Maybe the guide was referring to an extension cable? Second, I had to make Audioengine the default speaker device in Windows; the computer's speakers then became the default communications device.

Convenient and Easy Install

K-DUB from North Carolina on 8/22/2015

Crutchfield Customer Review (What's this?)

Exactly what I needed to get my TV audio output to my surround sound receiver and speakers without having to connect it directly. Just plugged the transmitter into the output on the TV and the receiver into my stereo, pushed a button to connect and bang - great sound.

Pros: Easy Setup, minimal hardware

Cons: Short cables included

TomD from Michigan on 6/10/2015

Crutchfield Customer Review (What's this?)

Quality product. Not disappointed in product or Crutchfield. Always good service. A bit overpriced for this type of hardware.

Pros: Easy install - no brainer. Great 16 bit sound.

Cons: A tad high in price.

Easy setup and excellent item

carlk from Tinton Falls, NJ on 11/5/2014

Crutchfield Customer Review (What's this?)

After the easy installation, connected the sender to a USB port on the CPU and the music sounded great! Had to move the speaker system with the receiver about 40 feet away from the CPU, and the connection is still excellent. One of the easiest setup's that I have ever completed.

Pros: easy installation, excellent product

Cons: None

Magic !

Michael from Charlotte,N.C. 28227 on 8/30/2014

Crutchfield Customer Review (What's this?)

I purchased the W3 to enable me to freely walk around my wedding venue and still play my music wirelessly. The unit works great for me but I will caution that you pretty much have to be line of sight with the receiver.If you have folks walking in front of you the signal might drop out.I intend to mount my transmitter at the top of a conduit and use a usb extension cable back to my computer to get a little higher as to avoid problems like this.All in all I am at least 60+ ft from my receiver and no problems at all.

Pros: Easy to connect, no interference from cell phones, etc.

Cons: none that I can see

Super simple bluetooth device.

Crutchfield customer from Charlottesville, VA on 7/23/2014

Crutchfield Customer Review (What's this?)

I purchased this unit for use with my DJ equipment. No more tripping over cables. After a quick look at the instructions, I was up and running in minutes. I did notice some infrequent audio drop outs. Moved the send and receive units a bit closer and problem solved.

Pros: Ease of use and setup. Very compact.

Cons: Occaisional audio drop out.

Audio engine I am so pleased!

Stevet from Rocky Mount, va on 3/29/2014

Crutchfield Customer Review (What's this?)

Super easy to setup and does exactly what I expected (wireless interface to a sub woofer)

Pros: Good price point. Could not be easier to set up. Works great.

Cons: None

Best sleek unit

Winston from Hawaii on 2/10/2014

Crutchfield Customer Review (What's this?)

Used on my first gig video presentation, never need that long RC cable again.

Pros: We'll engineered, the name says it self.

Cons: None


Crutchfield customer from Illinois on 12/21/2013

Crutchfield Customer Review (What's this?)

Couldn't be happier with this product! I was afraid there would be a lag when I hooked this system up to my Cambridge subwoofer, but it works flawlessly! No lag and it allows my subwoofer to be concealed and kept out of the way without having to run wires across the room. The setup was easy as well - literally plug it in to the wall, plug it in to the receiver and subwoofer, and it connects itself immediately. Virtually no setup.

Pros: Easy setup, no lag, works flawlessly.

Cons: None

It works as it claims without any noticeable sound quality loss.



Worth Every Penny ... If You Can Establish A Clean Signal

Flatpicnut from Morgantown, WV on 10/9/2013

Crutchfield Customer Review (What's this?)

After reading many reviews (on Crutchfield and elsewhere, which seem to universally average 4 out of 5 stars), I decided to give the W3 a try and purchased it "open box." My computer where the sender is located is approximately 35-40 feet from my stereo receiver, separated by a wall and a doorway. The W3 is mindlessly easy to set up. After establishing the connection with the W3 receiver without a problem, I flipped on Pandora on the computer. The sound was definitely redbook CD quality, so my first concern was allayed. However, my second concern - signal strength - was an issue right off the bat. Brief 1 sec. dropouts came at a rate of about 8-10 per minute. I had initially plugged the receiver unit into the "switched" outlet in the back of my AVR (located in a stereo cabinet). To get a better signal path with the sender, I was able to solve the problem by getting the W3 receiver out of the cabinet, dangling it from a couple of "cup hooks" that I put outside and in the back of the cabinet. I used a longer 3.5 mm to RCA patch cord to get the W3 receiver out of the stereo cabinet, and a USB extension cord so that I could get some distance between the W3 receiver and the power adapter. I moved it around until I found the best position (like fiddling with TV "rabbit ears"). I know it sounds like a hassle, but it has worked fine ever since. This gadget was worth the price and for me was a very cost effective alternative to the much more expensive Audioengine D2.

Pros: Redbook CD Sound Quality Flexibility In Sending Any Audio From Computer To Stereo Reciever Cost (versus Audioengine D2)

Cons: Signal Range/Strength

returned this product

Tom from Edison, NJ on 4/29/2013

Crutchfield Customer Review (What's this?)

I returned it and up graded to a NAD DAC (#745DAC1). This product worked fine, but it did not expand the music as much as I expected. The NAD does what i wanted and it is only $50.00 more.

Pros: easy set up

Cons: does not expand the music enough

Audioengine W3 review

Mike from Sturgeon Bay, WI on 2/3/2013

Crutchfield Customer Review (What's this?)

The Audioengine W3 is an excellent product. I'm using it to sent audio from my laptop to my main audio system. This takes the place of an i-Pod with a dock. The W3 sounds better than the i-pod setup. It only seems to be limited by the source sound encoding in i-Tunes (lossless versus a lower sampling rate). There was a setting in my laptop that needed to be changed for proper operation and the Crutchfield tech helpline saved the day. Once the setting was changed I have not had an issue since. Use tech support if you experience a problem. I would recommend this unit to a frend.

Pros: Works as advertised.

Cons: None. It seems to be a great unit.

Great Product

John M from Babylon,NY on 12/26/2012

Crutchfield Customer Review (What's this?)

Got this as a scratch and dent special. Plugged it into a USB port in my Dish box, and into an old receiver in my detatched garage, with outdoor speakers over my hot tub. Works great. Highly reccommend it!

Pros: Super easy installation, works great.

Cons: Can't complain

Audioengine W3

Bob B from Brookline, Ma on 12/7/2012

Crutchfield Customer Review (What's this?)

I purchased Audio Engine speakers to be able to stream music from the cloud using my tablet. This poorly conceived, badly designed product completely made this totally cumbersome. I understood up front that I would have to plug the receiving unit into ac power. Because this adapter used a proprietary sending devine (rather than bluetooth or wi-fi) I would have had to plug the sending unit in as well. It was just not going to work. Unit was returned for a bluetooth receiver. Much simpler, and the difference in sound was minimal (if any).



Excellent product, easy setup

CurtC from Woodward, OK on 10/1/2012

Crutchfield Customer Review (What's this?)

Love it! Needed a wireless option to connect a projector and DVD player and laptop and not have wires. This solution is perfect and works great. Sound is amazing and no interference. Used with the Audioengine A5+ speakers. Would buy again in a heartbeat.



Audioengine W3

BillT from Chattanooga, TN on 9/3/2012

Crutchfield Customer Review (What's this?)

The Audioengine W3 system is a good little system for connecting your PC to a powered speaker system, and the speaker system must be powered as the signal is certainly not overpowering. I gave it 4 stars because it does as it advertises but falls somewhat short as it seems to be affected by objects in its way more than I would like meaning I had to put the speakers closer to the PC than I would like. And given the fact that it stops the sound from coming through the PC speakers (though I haven't worked with my PC settings yet to see if I can overcome this) it seems as if I just moved my speakers to a different part of the same room rather than to a different room altogether. But again, it is a good system and when you get the issues worked out it does produce a pretty good sound.

Pros: Included in review...

Cons: Included in review...

Easy to set up and it sounds great!

Gary from Citrus Heights, CA on 9/1/2012

Crutchfield Customer Review (What's this?)

Very pleased with this wireless adapter kit. Easy to set up and it sounds great too. I enjoy listening to music over the web through my audio system. Highly recommend if you wish to send music wireless to your receiver.

Pros: Easy to set up.

Cons: None

Audioengine W3. Wireless audio adapter kit.

Michael from Daytona, FL on 8/20/2012

Crutchfield Customer Review (What's this?)

Although i am an Oxford graduate, I am also a technological ignoramus. IPods, Iphones, Blackberries, MP3s are utterly beyond my comprehension. I simply wanted a device that could transmit sound from my computer room to the living room. Had a chat with one of your agents (Rocky) about this. He finally decided that he had the ideal solution to my problem. His advice proved to be correct. It was exactly what I needed. Now I can listen to BBC radio, experiencing the same kind of sound clarity which I would were I living in London. If anything, the sound quality is superior to that of a live radio broadcast.

Pros: Very easy to install. Even a dunderhead like me managed to do so without any hitch whatsoever. When you need to transfer the sound back to the PC speakers, you just extract the adapter from the front of the computer. It is that simple.

Cons: Cannot think of any offhand.


Hands-on research

Product Research


Overview: The Audioengine W3 is a 16-bit wireless system that is designed to connect your audio components wirelessly. The W3 handles USB audio, up to 16 bits/48KHz with no compression, as well as analog audio via a 3.5mm minijack. The W3 kit includes a Sender (transmitter) and Receiver; the system is designed to deliver an audio signal wirelessly between two components. This system will work in many different applications, including (but not limited to) a computer sending audio to powered speakers, a computer sending audio to a stereo or A/V receiver, an iPod or other portable player sending audio to the Audioengine 5+ powered speakers (the A5 is specifically mentioned here because it has a USB port to power the W3 Receiver), and an A/V receiver sending audio to powered subwoofers or powered speakers.

Note: The W3 is natively compatible with Windows 2000/XP/Vista/7/8 and Mac OSX. There are no drivers or software to install.

Two Part System: The W3 consists of 2 parts, the Sender and Receiver. The Sender transmits audio from your computer through USB audio or from any product with a 3.5mm minijack or RCA audio output. The other end of the W3, the Receiver, delivers audio to any product with minijack or RCA audio connectors.

  • Sender: The W3 Sender is powered through its USB plug; one USB AC power adapter is included with the system to power either the Sender or Receiver. If not powered by the included adapter, the Sender can be powered by a computer, iPod power supply, or numerous other USB power supplies currently available. The audio input is a 3.5mm stereo minijack. When used with a computer, the Sender acts as a sound card and receives its audio input through the USB port, so no connection to the minijack is necessary.
  • Receiver: The W3 Receiver is powered through its USB plug; one USB AC power adapter is included with the system to power either the Sender or Receiver. If not powered by the included adapter, the Receiver can be powered by Audioengine A5 powered speakers, an iPod power supply, or numerous other USB power supplies currently available. The audio output is a 3.5mm stereo minijack; no audio signal is transferred through the USB connection.

Note: If you are wirelessly connecting a powered subwoofer to an AV receiver using the W3, then you will need one stereo minijack-to-RCA cable and one stereo RCA cable (both sold separately) to go along with the included minijack-to-RCA adapter. If you do not use the included minijack-to-RCA adapter, you can use two stereo minijack-to-RCA cables (sold separately).

Pairing: The Sender and Receiver in the W3 kit are linked together at the factory, so no pairing is necessary. If you have several W3 systems, multiple Receivers can be paired with each Sender, and vice versa, but each can only communicate with one of the other at a time. The W3 can transmit to up to 3 receivers (772W3R, sold separately) simultaneously.

Note: The newer chip-sets used in the W3 are not backwards compatible with the earlier Audioengine W1 or W2 wireless systems.

Proprietary Wireless Transmission: The W3 wireless kit transmits uncompressed PCM audio (15Hz-22KHz; +/- 1.5db) in the 2.4 GHz range (2.4-2.4835GHz) using a proprietary WiFi 802.11 protocol specifically designed for audio (up to 100'). The system avoids interference by constantly monitoring the entire 2.4 GHz spectrum and choosing the channel that can achieve the cleanest transmission. The system detects deteriorating conditions on the current channel and switches if needed in under 20 ms, without any interruption in the audio stream. The W3 also employs dynamic transmit power control, meaning it transmits with only as much power as required to maintain a clear audio connection. This makes W3 coexist better with other 2.4 GHz devices, including WLAN, Bluetooth, and other Audioengine wireless devices. The W3 incorporates a real-time streaming transmission technology designed specifically for music. It includes six quality protection innovations to achieve a robust wireless audio link.

  • Error-tolerant coding that incorporates forward error correction (FEC) coding. FEC ensures that lost bits can be completely reconstructed for common interferers and sources of bit errors. The coding is optimized for lossless performance against common and known interferers. FEC also enables error detection so the system knows when and where data is corrupted. It is analogous to techniques employed on Redbook CDs where the laser head incurs bit-errors as a result of imperfections in the pickup of data from the optical media.
  • For larger interferers, W3 employs sample interleaving and sample error concealment (SEC). This allows W3 to compensate gradually during periods of increasing signal degradation, thus minimizing audible discontinuities. When encountering interference bursts (up to 6ms in duration) SEC can recover every alternate sample, after which the hardware DSP performs linear interpolation to recover lost samples.
  • Packet error concealment (PEC) ensures there are no jump discontinuities in the audio stream during periods of severe interference, giving the system time to find a clean channel.
  • W3 employs intelligent, Dynamic Frequency Selection. The system avoids interference by constantly monitoring the entire 2.4 GHz spectrum, choosing the channel that can achieve the cleanest transmission. As conditions on a currently occupied channel deteriorate, the system detects this, and switches channels (in under 20 ms) without any interruption in the audio stream.
  • W3 employs dynamic transmit power control. This means that W3 is transmitting with only as much power as required to successfully maintain a clear audio connection. This makes W3 coexist better with other 2.4 GHz devices, including WLAN, BT, and other Audioengine wireless devices.
  • W3 combats RF fading, or multi-path-induced signal-strength fluctuations, by natively supporting antenna diversity. Support for dual antennas allows the system to "navigate" around zones of decreased signal strength by creating four possible antenna-to-antenna paths for the system to choose from on a continual basis. The end-result is an overall improvement in audio signal robustness due to an improved link margin.

Power Requirements: The Sender and Receiver both require power, which can come from a USB computer port, the included AC power adapter, the optional Audioengine USB Power Adapter, or from any other USB charger (such as an iPod charger). Another power source is the Audioengine 5+ powered speakers (sold separately), which are equipped with a USB power port on the rear panel. If you're using the W3 Wireless Kit for a receiver/subwoofer application, a second USB power supply may be needed.

So I could connect my computer to my NAD Receiver and watch a movie from my computer without a sound delay (Bluetooth has a delay) and not have to run a long RCA cable from the back of the NAD across the room to the Mini headphone jack in my computer. [ Jonathan  Sep 01, 2018 ]
so i could pair my AudioEngine HD6s better to my computer! [ Thomas  Jan 13, 2018 ]

This looks like a great way to establish wireless connection from my TV to my JVC reciever. as I am intending to mount it on a brick wall, Wiring will be difficult. [ Steve  Jul 19, 2017 ]

4 questions already asked

As for the connection question, I'd contact the manufacturer's tech line or look at the instructions for the transmitter (available on line?). I will say these do not operate flawlessly. I connected one of these to our TV in one room and speakers in the adjacent room partially separated by a wall and we had a lot of drop-outs. Not bad for a TV show where there are natural breaks in the audio, but for music payback from out TV which is continuous audio, the drop outs were very annoying. Again, I'd talk to the manufacturer to get a better idea of just how well these are expected to work for your application and equipment placement. [ Christopher  Dec 14, 2018 ]
not sure [ Robert  Dec 14, 2018 ]
Perhaps I am not the best person to answer this, as I am a devout technological Luddite; however, I did incorporate the "second zone" RCA output on our Onkyo 8270 to send a signal to the sub-woofer using the Audioemgime gear. I chose to power the main speakers coventionally via 14awg speaker wire. This would have not been possible without the help of Shawn at the Crutchfield AV Design Group. He was a great resource on this subject. [ Jean  Dec 14, 2018 ]
Sorry, I am only using one at a time. Make sure you stay with Crutchfield as they do excellent returns and my first one over heated and was replaced fast and free. Also, this wireless connection is very sensitive to line of site; if stuff gets in the way it may not work well and you want to use it on the same floor. It barely worked when on two floors even with open concept. Lastly tech support was good at both places, but other devices near the frequency band will interfere, so these are a pretty fragile wireless link in my experience. Again, good product, excellent support, but not for every application for sure. Good luck. [ Lawrence  Mar 21, 2017 ]
Don't truly know , I would imagine if you synced one set at a time . I can tell you that they work very well , audio quality is great . Good luck [ XCErider  Mar 21, 2017 ]
It doesn't work that way. It works anywhere that you want to connect an stereo audio output (like a headphone jack) and a stereo audio input (like audio in jack) on your stereo receiver. You can't connect it to a speaker. I suggest that you chat with the folks at crutchfield to find a better solution for what you want to do. [ jimchandler63  Mar 20, 2017 ]
I was using this set up to send a signal from my AV amp to a Polk powered subwoofer. I stopped using it because of a slight audio delay. [ CHRIS  Apr 16, 2014 ]
Audioengine rates the W3 as having a <20ms latency, so technically yes there is a delay. However, 20ms is .02 seconds and only anyone with super human hearing would be able to detect that. I use the W3 to run my wireless sub and cannot detect any delay in relation to the rest of the signal. [ TODD  Apr 16, 2014 ]
Thanks guys! Appreciate the replies. [ Peter Wood  Apr 14, 2014 ]
never used returned for credit. sorry i couldn't help ! [ JOHN R  Apr 14, 2014 ]
There is no signal degradation or latency using the W3. [ STEVE  Apr 14, 2014 ]
If there is a delay then it is very slight, as I have not noticed anything. [ ROBERT  Apr 14, 2014 ]
Thanks for your question Mike. I believe what you are looking for is the Audioengine W3R. [ Jeff  Dec 12, 2013 ]  Staff
