Powerful sound from a versatile wireless speaker

Think you can't get great sound from streaming music to a wireless speaker? Then try the Pioneer A4 and let your ears be the judge. The A4's compact 3-way design features five drivers, including a built-in subwoofer for real bass that will give your music depth and power. And because it streams music over Wi-Fi rather than Bluetooth®, you can be sure that all the details of your music are delivered to this versatile speaker, with no bits or bytes lost in translation.

Pioneer A4 Wi-Fi speaker with Airplay

The Pioneer A4 delivers powerful sound from a variety of streaming devices.

Plenty of ways to stream music

The A4 offers several different ways to stream audio from various devices. If you have an iPhone®, iPod touch® or iPad®, you can use AirPlay to stream your favorite tunes directly from these devices to the A4. Or if you're a PC loyalist with a networked hard drive, your entire collection is just a swipe away thanks to the A4's DLNA compatibility. Android™ users can even stream music from HTC One smartphones. The A4 also supports Pandora® and vTuner® Internet radio, so you can discover even more artists and genres beyond your personal music library.

No Wi-Fi? No problem, with Wireless Direct

So what about that room with little or no Wi-Fi reception? Thanks to Pioneer's exclusive Wireless Direct, the A4 can interact wirelessly with your Apple device for music streaming independent of your home network. This allows for even more set-up flexibility in your home, so you can enjoy the A4's big sound beyond the reaches of your Wi-Fi signal.

Improve your home's décor

The A4 will improve any room not just with its solid sound, but also its sharp looks. The gloss black enclosure and black metal grill give it a clean, streamlined profile. The control panel features touch sensors rather than buttons, for a sleek appearance that's super-responsive. The rear panel has USB and minijack inputs, as well as an Ethernet jack, for wired connections to music sources and a network router.

Use your smartphone as a remote

The A4 comes with a remote. But if you're playing music from a smartphone, you'll probably want to control the A4 with that same device. Just download Pioneer's free ControlApp for Apple and Android, and your smartphone will handle all the A4's functions just as easily as it streams your music.

Pioneer A4 - Great Value

Written By DMP, Louisiana on Sunday, January 19, 2014

Crutchfield Customer Review (What's this?)

Great sounding speaker. Bought it for my teenage daughter's room so she could stream music from her iPhone and she loves it! More than enough to fill up a 12 x 15 room - loud enough for a teenager and too loud for her parents! The sound quality is great as well, clear highs and full atmosphere bass. It's a little tricky to setup but a little internet research and we got it working with little problems. I highly recommend it.

Pros: Attractive cabinet, great sound, plenty loud enough for a teenager. Compared to Sonos pricing, you can beat the value

Cons: A little tricky to setup but nothing overwhelming

Excellent Sound, Good system

Written By Loki, Rochester, NY on Thursday, January 09, 2014

Crutchfield Customer Review (What's this?)

I purchased this speaker for the Air Play capability so I could use my music collection on my computer without having to get an iPod, or some other MP3 player, to have the music playing in a room across the house from where my desktop was set up.

Getting the wi-fi set up was a bit of a hassle, but got it done with only few random curses (usually because I was mis-interpreting the perfectly clear English directions on the set up sheet.). I would have preferred to have the owner's manual shipped or at least on a CD with the set up, but once set up, it was playing nicely with excellent sound fidelity.

The two problems I have are, first the remote that came with my unit is not working well. The original battery for the remote couldn't make it work at all, and having replaced the battery, it's only limited utility. Since having a remote was something I could do away with, anyways, I haven't made an issue of it, but if that's something you care about I can't say it provides a useful interface.

More of an issue is that when rebooting the speaker can take up to 20 minutes to reconnected to the wi-fi and the computer. Since I wanted this for music for sleeping to, this can make for some frustrating time trying to sleep - however I've only had the signal drop once, requiring a full restart, since I got it set up - and that may be more because of the construction of the house interfering with the wi-fi signal. I'm still getting 95%+ up time from it, and very happy.

Pros: Great sound. Air Play is easy

Cons: Long start up time; remote not very useful

Best speaker for $200, period.

Written By JP, Raleigh, NC on Wednesday, December 18, 2013

Crutchfield Customer Review (What's this?)

Where are you gonna find a fantastic brand new speaker for this price? I bought five speakers and I returned all of them. If your budget is a little more, go with the B&W Z2 but if money is an issue, get the Pioneer A4, before they are discontinued. After ordering different speakers from several websites, I ended it up with the following items: (yes, my wife thinks I'm crazy) Klipsch MC3, Bose Sound Dock Series III, Marshall Stanmore, JBL Venue on Beat LT, B&W Z2, and the Pioneer A4. I listened to more than 100 songs between these speakers and all I can say is that none of them is bad. All of them are well balanced and you can not go wrong with these options. However, the Pioneer A4 was the only one that at high volume never distorted and created a big deep clean bass. This means that if your are planning to use it as a party speaker, go for it. If you are looking for a rich, clean sound at low and medium volume go with the B&W Z2. The Marshall Stanmore sounds great at the store but at home, does not match the big winner Pioneer A4. Set up requires to take the time to read the instructions carefully. If you like plug and play get the other ones from above. I use my Pioneer A4 in my cave (garage).

Pros: Price, amazing powerful sound, sub-woofer, tweeters.

Cons: Remote, weak in the mid-range department, set-up is more time consuming.

Absolutely phenomenal for the price

Written By Kris, Reno, NV on Friday, November 29, 2013

This thing is amazing. For those of you having issues setting it up, the two easiest ways are, if you have an iOS device, turn on the pioneer and wait for the power light to stop flashing. Then, plug your iOS device to the USB port in the back of the Pioneer. Unlock your iOS device. Then, press and hold the input button on the front AND the network button on the back for three or more seconds. Your iOS device will ask if you want to share your network settings with the pioneer. Click accept and...voila! Or, use WPS on your router.

For the price, this thing is rock solid. Not exactly balanced sound, but for the price, you cannot beat the sound, form factor, features, or the name. This thing rocks. Buy it. It's almost as good as the Sonos Play:5 at half the price.

Pros: Everything. Sound, features, setup, price...

Cons: It could have a more balanced sound. It seems to boost both ends of the spectrum which leaves the midrange a bit dull. But I am being very nitpicky here.


Written By Drew, San Antonio TX on Tuesday, November 19, 2013

Crutchfield Customer Review (What's this?)

Terribly disappointing. Airplay doesn't seem to work on all iphone apps. I demo song ideas on voice memos and thought I could play them since it's got airplay for iPhone. Uh. No. I have a sonos that works much more effortlessly. Not a fan of this thing. And setup sucked. Made you feel like a third grader reading Latin. Live and learn.

Cons: Setup much more confusing than other devices of similar design. Seems to need to be turned on each time you want to play it, unlike sonos.

Pioneer A4

Written By Peter W, Carmel,NY on Sunday, November 17, 2013

Crutchfield Customer Review (What's this?)

Very happy with this WIFI speaker. Set up 3 minutes. Use utube video, a breeze. Fine clear sound. Great bass but not to overwhelm. Looks great, simple and fits any room. Plenty of volume for any room. Would buy it again in a heartbeat! Hard to believe such good sound from a relatively small package. Quick free shipping

Pros: Set up. Sound. Appearance.

Cons: Rarely at one frequency a momentary buzz at midrange. Agree written set up instructions confusing. Use the u tube video, simple as can be!

Too Complex To Set-Up

Written By MelM, Tucson, Az on Wednesday, November 06, 2013

Crutchfield Customer Review (What's this?)

I ordered it event though the reviews said that the set-up and instructions were terrible. I gave up after a few tries and sent it back. The mammoth instruction sheet was worthless. Another reason to send it back was that the power brick was never pictured and was larger than ones I had for my very old laptop computers. I am sure the sound would be great, but the brick made it ugly where I was going to place it. Crutchfield was great about the return. I am very happy to say they are my preferred audio supplier.

Pros: I don't know the pros since I gave up on the set up.

Cons: Complex set-up. Brick power supply never pictured, but is way too large. It should be built in.

Reviews for the Pioneer A4

Written By Adam, Charlottesville, VA on Thursday, October 31, 2013

For what I paid, the Pioneer A4 is a good buy. It doesn't have the crisp sound I was hoping for, but it's sitting in a kitchen and does not need to fulfill that requirement.

Pros: Being able to wirelessly connect from my phone or ipod is great. It totally eliminates extra wires. The sound is good for what it is and has no problem filling the space that it is in.

Cons: Connecting the speaker to the router was a pain, but that could be attributed to me not knowing what I was doing. When turning on, it takes an inordinate amount of time to connect to the router.

Too confusing to use

Written By LLW, Harrisburg, PA on Sunday, October 27, 2013

Crutchfield Customer Review (What's this?)

I am sorry I bought this speaker. The instructions are impossible to follow. I got it to work once wirelessly with my iPad with Spotify for 30 seconds but that was it. I think the problem is that I'm not getting a LAN connection but after several hours of trying to figure it out I am giving up. The blinking lights on the panel don't even light in their different colors with any consistency, at least that I can tell. You need to be a genius to figure this one out and obviously I am not. When I had it working once, the sound was great but its useless if I can't get it to work. Very frustrating, and I would give it less than one star if I could.

Best Wireless Speaker

Written By B, San Francisco, CA on Saturday, September 21, 2013

Crutchfield Customer Review (What's this?)

This is the one. Best wireless speaker hands down. If you need to be portable, the A3 is also a great product - it includes a battery but sacrifices the "sub" woofer, which some listeners may prefer. The A4 thumps out some solid bass and clean highs. The center 4" woofer and the ported back do a good job of pushing bass around a small room. Perfect for a bedroom sized space. I like the elegant lines and classic black. AirPlay works great, the app for iOS makes streaming and volume control a breeze, and the USB port allows for playback, charging and remote control of your device....I use this a bunch with my old iOS devices. Definitely, a 5 out of 5. Just buy it already...

Pros: Hi-Fi sound, deep-rich bass, simple but elegant design, wireless galore...including wireless direct (no internet needed to enjoy wireless playback) perfect size, set-up was a snap using the iPhone, 5 drivers and a series of dedicated amps

Cons: No EQ, can't disable the bass for late night listening...sorry neighbor

Amazing sound

Written By Tommy 2, Watervliet MI on Saturday, September 21, 2013

Crutchfield Customer Review (What's this?)

It is a bit time consuming getting the speaker programmed but well worth the effort and time. The sound produced from this speaker is amazingly clear, I hear my music played at a whole new level. Reminds me of the older amplified split systems with the huge speakers, I really didn't think I could get this sound out of a wireless speaker. I couldn't get this quality of sound out of my Bluetooth Bose Soundlink, perhaps it's a combination of airplay and the outstanding engineering of this speaker. Whatever it is I'm one happy customer.

Pros: Great Sound, Airplay, An Engineering Marvel.

Cons: Time consuming programming, for me anyway, but worth it!

Great sound for a little box.

Written By MRDS, Guam on Sunday, September 15, 2013

Crutchfield Customer Review (What's this?)

The other reviewers were correct in that programming could be time consuming. The easiest way around it is using Airplay via your Apple iPhone/iPod/iPad. Once you get started, you will be amazed at the sound. I was hearing SFX from the movie I was watching that I did not notice before, even when I had headphones. I wish Pioneer did a better job with the physical design and offered another color other than black.

Pros: Great sound.

Cons: Program instructions.

Nice speaker

Written By A, Arlington, VA on Wednesday, September 11, 2013

Crutchfield Customer Review (What's this?)

This is a pretty good sounding speaker, with some nice features. When on sale (about 50% off) it is reasonable, but list price seems high, and at that price point there is other competing products to consider.

Pros: Nice features: Airplay streaming, built in internet radio tuner and Pandora client, aux input, and iPhone/ipod usb input.

Cons: The Pioneer Control App is clunky and there is much room for improvement.

Another great speaker from Pioneer

Written By BobH, ELLIJAY, GA on Sunday, August 25, 2013

Crutchfield Customer Review (What's this?)

I was reading about Airplay, but didn't have an Airplay speaker, when I saw Crutchfield had the Pioneer A4 for a great price. It came quickly in excellent condition. It was easy to set up, although the instructions weren't well laid out. The speaker system is everything I hoped for and more. The sound is superb, with lots of subtle detail. I had it set up to play on my iPhone, iPad, and Macbook in no time.

Pros: Easy to set up. Great sound.

Cons: Instructions could be laid out better.

Pioneer A4 Big sound-small package!

Written By Big E, Ohio on Saturday, August 24, 2013

Crutchfield Customer Review (What's this?)

I purchased this product for dual purpose use. Mainly backyard usage for listening to internet radio through my iphone. I was a little confused with the airplay feature, but pretty sure problems are with wi-fi signal and total lack of tech info/understanding on my part. Plugged in using usb cord and was pleasantly surprised by the sound quality-full sound and very good bass! Way more than I expected. Also used this for an outdoor cruise in for background music, but was pleasantly surprised when my wife asked me to turn it down a little so the people nearby could hold conversation more clearly. Overall, love it!

Pros: Good sound quality, not too large or heavy, easily transportable.

Cons: Would have liked rechargeable powerpack as on A3. Airplay feature a little confusing?

For the price it can't be beat. Amazing full sound from a small package. Easy set up

Pros: Price. Set up. Design. Sound.

Cons: Needs constant power source. Would be nice to have a chargeable feature.

solid speaker

Written By Mark, Eden Prairie, MN on Wednesday, July 17, 2013

Crutchfield Customer Review (What's this?)

I love this speaker. The setup was easy to do for connecting the wifi. I can click play in iTunes at my computer and the speaker powers on automatically. The only downside that I see is that I can forward and reverse through my play list, but once I hit pause with the remote, I have to restart playing from my computer. I'm hoping there is a work around to this. It would be nice if they had designed in a base and treble adjustment. I had to download an equalizer app so I could adjust it with my iPhone.

Pros: sound, plenty of bass, plenty of power

Cons: needs bass and treble controls

Pioneer A4

Written By scotto, Hawaii on Tuesday, June 11, 2013

Crutchfield Customer Review (What's this?)

Sounds great and solid bass. Hard to set up over the WI-FI. the directions are a little confusing because there are so many different ways to connect. Each gets a minimum of instruction. I could never get it to stream over my air play/ apple, but I think its my computers fault- not the pioneer. I now stream it wirelessly using Airfoil and it works perfect every time.

Product Research


Overview: The Pioneer A4 is a compact and versatile wireless speaker featuring WiFi, AirPlay, DLNA, and HTC Connect technology. The Pioneer A4 also features a USB port for iPod direct connection and a 3.5mm auxiliary input for connecting almost any portable audio source with a headphone output. The unit comes supplied with a wireless (IR) remote control for added convenience. You can connect multiple Pioneer A4 systems to your home network for music throughout your home.

Pioneer Sound: The Pioneer A4 wireless speaker system has been developed from the ground up by Andrew Jones, Pioneer's world-renowned Chief Speaker Engineer. A single 1" tweeter, dual 3" midrange drivers, and a single 4" subwoofer housed in a bass-reflex enclosure powered by 10W+10W+20W amplifiers provide a clear, natural, and powerful audio experience you come to expect from Pioneer.

Dual Network Connection: The Pioneer A4 is equipped with dual network connection methods. There's an RJ-45 LAN (Ethernet) port for direct wired connection to your home network, and there's also the built-in WiFi (b/g) feature that includes WiFi Protected Setup for safe and secure connection to your wireless home network. The unit's network connection lets you listen to music from your Apple device (via AirPlay) or Android smartphone (via HTC Connect or Wireless Direct), your music files stored on your Windows PC (via DLNA), and music content from Internet Radio (via firmware upgrade).

Note: This unit's RJ-45 Ethernet port supports 10BASE-T/100BASE-TX and requires an Ethernet (LAN) category 5 or higher cable, Router, Modem, and Internet connection. When using a wireless LAN connection, your system must feature an wireless router/access-point which supports WiFi (b/g).

Wireless Direct: When using Wireless Direct, you can connect directly with other WiFi-enabled devices, (such as your smartphone) without using a wireless router. You'll be able to wirelessly transfer audio content to the Pioneer speaker system without connecting to your home network. WiFi Direct completely bypasses your WiFi access point/router, so it's easy to set up. Only one WiFi-enabled device can be connected to the Pioneer A4 at the same time through Wireless Direct mode. Wireless Direct doesn't have an internet connection, so you cannot access the internet.

Note: Wireless Direct should be used only as a temporary connection under conditions where a normal router cannot be used. This connection is not encoded, so the music stream and music metadata will not be encrypted. Streaming of copy-protected audio content is not supported.

DLNA Certified (1.5): The Pioneer A4 is DLNA 1.5 certified. This means you can stream your MP3, AAC, WMA, WAV, or even FLAC music files (up to 96kHz/24-bit) from your Windows PC or laptop to the Pioneer wireless speaker. This unit allows for the streaming of audio files stored on the following DLNA-compatible devices.

  • PCs running Microsoft Windows Vista or XP with Windows Media Player 11 installed.
  • PCs running Microsoft Windows 7 with Windows Media Player 12 installed.
  • DLNA-compatible digital media servers (on PCs or other components).

Audio File Type Bit-Rate Sampling Frequency
MP3 (.mp3) 8-320 kbps 32 to 48 kHz
WMA (.wma) 5-320 kbps 32 to 48 kHz

Flac (.flac) 16-bit, 24-bit 32-96 kHz (wired)

You can even access your iTunes account from your iPod touch (2nd/3rd/4th/5th gen)/iPhone (3GS/4/4S/5)/iPad running iOS 4.2 or later, via Apple's free Remote app.
