Our take on the MartinLogan Dynamo™ 700W

Ever have trouble finding the perfect spot for your sub? Well, with MartinLogan's Dynamo 700W subwoofer, you'll have lots of options. This versatile sub's standard down-firing setup is perfect for placing it in corners or along side walls. But if you're looking for a more discreet placement such as in a cabinet with your other home theater gear, you can easily convert it into a front-firing sub by simply removing and reorienting its detachable feet.

A sub that fits where you want it

Ever have trouble finding the perfect spot for your sub? Well, with MartinLogan's Dynamo 700W subwoofer, you'll have lots of options. This versatile sub's standard down-firing setup is perfect for placing it in corners or along side walls. But if you're looking for a more discreet placement such as in a cabinet with your other home theater gear, you can easily convert it into a front-firing sub by simply removing and reorienting its detachable feet.

MartinLogan Dynamo 1500X converting from front- to down-firing.

Wireless convenience right out of the box

Even if you're willing to place your sub far from your receiver, you might not want a long wire running between the two. No worries, thanks to the 700W's built-in wireless receiver and included transmitter. So you can feel those deep rumbling movie sound effects without tripping over a cable when you get up to get more popcorn.

Not just for explosive movie soundtracks

When you add a subwoofer to your full-range speaker system, your movies and music will sound fuller and more dramatic. The Dynamo 700W accomplishes this without taking up valuable real estate in your living room or home theater. The sealed enclosure is constructed of high-density materials and reinforced with solid internal bracing to minimize cabinet resonance for cleaner sound. The 10-inch speaker is driven by a high-powered built-in amplifier that delivers 300 watts of continuous, clean power. Both are optimized for low noise and distortion, to produce bass that is not only bold, but detailed and tight rather than loose and boomy. That makes this sub a great performer with movies and music — not to mention a great match with MartinLogan's fine lineup of full-range speakers.

MartinLogan Dynamo™ 700W

Crutchfield customer from Mishawaka, IN on 12/9/2018

Crutchfield Customer Review (What's this?)

Added this sub to increase the range of my Martin Logan LX16s. Does a fantastic job and would have given it 5 stars were it not for the fact that the controls end up on the bottom of the speaker when you go to a front firing setup. Doesn't make any sense that you have to tip the speaker over to access the controls. I think I have it set to the level I want but still . . .

Pros:

Cons:

Awesome sealed sub - very compact

mark from Hammond, IN on 12/8/2018

Crutchfield Customer Review (What's this?)

Received this to replace an old B&W 100W sub I had. This one is very nice -- great clear sound, reaches deep, beautiful cabinet, solid feel, and very well made. Only hiccup I had was with the included wireless adapter (it would not stay on unless I wiggled the little plug --- it appears to be a loose socket on the wireless module where the AC adapter plugs in. This led to the sub dropping out due to the external adapter losing power). Otherwise, awesome sub and I do recommend this unit to others....

Pros: very clear sound, deep base, nice features, beautiful cabinet.

Cons: None with the sub itself. With the accessory -- the external wifi adapter included with it would not stay powered on. The Sub itself was flawless.

Great addition with my ML Vision soundbar. Easy to install and setup. Added a lot more bottom end bass than expected. Highly recommended

Pros:

Cons:

Highly recommend ML 700W for its powerful, tight sound!

Eric from Belchertown, MA on 12/4/2018

Crutchfield Customer Review (What's this?)

Exactly what I was looking for: to fill a medium-sized house (1740 sq ft, open concept room layout, cathedral ceiling) with tightly rumbling sound. Quality subwoofer, has a full range of controls and a wired or wireless connection to easily satisfy harder-to-wire spaces. Tons of power! Will be experimenting with side-firing by placing it directly behind sofa, because I'm finding that down-firing is too much shaking for our wood-frame house at higher volumes. Long-term plan is to relocate subwoofer to basement, after we finish the remodel.

Pros: Tight Powerful Full range of controls Down or side-firing Wireless or wired Compact

Cons: Blue lights are super bright (recommend to cover with tape) Can't think of ANY OTHER CONS

Excellent 10 inch sub

Ben from Aubrey, TX on 12/2/2018

Crutchfield Customer Review (What's this?)

This is my first powered subwoofer, it is replacing the sub that came with Bose lifestyle 18 theater system. My room is a standard living room ... approx 20 x 15 open concept house; I do not have a dedicated theater / media room. The bass is a great compliment to the existing 5 Bose speakers and a tremendous upgrade from their factory unit. Installation was extremely simple and the packaging was designed to ensure no damage during transit. I found the instruction manual very easy to understand with the suggested setup and explanation of the adjustments available. The included wireless transmitter and ability to change down-firing or front-firing were the 2 main reasons I selected this over alternate subs. Pairing was a breeze and there is no latency - the lows hit when they are suppose to. I have it in the down-firing position and it shakes the walls of my house. It sounds louder and deeper the further you get away from it. Highly recommend if you are wanting a 10 inch versatile sub to complete your theater setup.

Pros:

Cons:

Great sound, issues with wireless connection

Namir from Annandale, VA on 12/1/2018

Crutchfield Customer Review (What's this?)

I have been enjoying a dated but fine Boston Acoustics 5.1 system, and the sub-woofer died. I purchased the new ML to replace it, and acoustically it is great. It fills the large (but not huge) room with excellent bass for adventure movies, which was the main reason I got it. (Star Wars, etc.) There is one disappointing issue that I may eventually sort out, and they do warn you about it: since I cannot place it close enough to my receiver to hardwire it in, I use the wireless connection that comes with it. As warned, all the other ambient RF signals in my house (WiFi mainly, but who knows what else) cause some interference. Thus when the subwoofer is on, you get some low level rumblings from time to time. It's a little annoying, but not catastrophic. What I do now is turn the sub-woofer down until I really it need it, and then just crank it for high powered movies. Clearly not the best solution. I am playing with moving the transmitter and receiver (for the wireless connection to the receiver) around, and hopefully I will soon find a "null" in my ambient RF where I can eliminate the interference.

Pros: Acoustically great for a relatively small footprint.

Cons: Ambient RF (i.e. WiFi) produces unwanted "rumbling" from time to time, when using the wireless connection.

MartinLogan Dynamo™ 700W

Crutchfield customer from Fernandina, FL on 11/25/2018

Crutchfield Customer Review (What's this?)

As our first home theater we don't have a comparable reference point, but this sub was simple and easy to connect. We tried both wired and wireless methods and cannot tell a difference in sound between the two methods. The woofer is small which is ideal and it produces clean crisp sound. Make sure you set your LFE to 120Mhz and all your speakers to small and 80Mhz crossover and it produces the best effect. Did not rely on Audyssey to auto-set levels, as it cannot work with an externally powered sub. We don't listen to over the top loud content, so we cannot rate it on sheer volume, but Bladerunner 2049 sounded simply awesome as well as so does soft Jazz and Netflix movies streaming in 5.1. Using in a 7.1 system with Denon X3400, 6 Polk ceiling mounted 70RT's, and a Polk a4 Center. Medium size room.

Pros: Small size Acoustic Suspension Wireless Good crisp sound

Cons: None Will probably eventually purchase a 2nd Sub to even out the natural highs and lows in different seats in our living space, but not a necessity

Mighty Mini

Greg from Phoenix, AZ on 11/21/2018

Crutchfield Customer Review (What's this?)

Very musical with great slam and impact perfect for movies as well. Extends flat to below 25 Hertz in my room per my sound level meter. Setup was as easy as unboxing it and plugging it in. I'm using the SWT-2 wireless interface and it works perfectly. It would be more ideal if the subwoofer would auto turn-on with lower signal levels or turn on whenever the wireless link is active, however once it's on it stays on even at low listening volumes, which is nice.

Pros: Clean, deep bass extension Very musical Great slam for movies Compact

Cons: Auto turn-on requires somewhat high audio signal

ML 700W

Dan from Sparrow Bush, NY on 10/21/2018

Crutchfield Customer Review (What's this?)

Always wanted a high quality 2 channel system. I'm not really a stereophile but appreciate well made functional equipment. Upgraded my speakers from Infinity to Martin Logan LX16 and the ML700W acoustic suspension. The Infinitys were fine and were also purchased from Crutchfield. I just wanted a bit more of a refined sound. Got what I wanted with this setup. The bass it tight and the down firing woofer adds bottom without being muddy or obtrusive. Love the phase capability and operate in 2 channel mode. If my 67year old ears notice a difference, I think that says something. I don't use the wireless capability.

MartinLogan Dynamo™ 700W

Crutchfield customer from Auburn, CA on 10/18/2018

Crutchfield Customer Review (What's this?)

Adds just the right amount of "lower end" bass to round out my book shelf speakers. The Martin Logan sub gives an all around fullness to the music without being overpowering. Hard to explain, but you can hear the difference. I listened to a couple of other subs and this one fit what I needed.

Pros:

Cons:

Great bass from a small package

Jordan from Lakeside, CA on 10/8/2018

Crutchfield Customer Review (What's this?)

Very nice addition to my system, fills the bottom up nicely. Very easy setup.

Pros: easy setup sounds great

Cons: Blinking "connect" light that cannot be shut off (a piece of tape over it fixed that though).

Raj from San Diego, CA on 8/8/2018

Crutchfield Customer Review (What's this?)

Amazing!! This is honestly one of the smallest 10" subs on the market but you would have no idea by listening to it. My goal with my new 5.1 setup was to feel like the Earth was shaking. This sub did not disappoint. Watched Dark Night and when the Batmobile crashes in, the whole room shook. It was amazing.

Excellent sub, easily fills the room

Tim from Saint Charles, MO on 2/5/2018

Crutchfield Customer Review (What's this?)

Excellent sub! Easily fills the room. After going through the setup on my Marantz SR7011 receiver, I've got the volume set at about 40% to get to about 73 dB and it balances the room very well. The room is open on 2 sides, 12ft ceiling, wood floor with large area rug. The flexibility to set it as downward firing or forward firing is a nice feature I didn't think would make a difference. I like the forward firing setup better for my space. The wireless option seems like a nice option to have but mine is hard wired. Current setup is 5.1 but looking forward to adding a few more speakers and I will definitely consider adding more MartinLogan products.

Pros: Flexible setup, excellent power

Cons: Flashing blue wireless light is annoying and the only solution I've found is ducktape.

MartinLogan Dynamo™ 700W

Richard from Huntersville, NC on 12/10/2017

Crutchfield Customer Review (What's this?)

Great sounding sub, but wireless feature was disappointing. My setup is ML's all around in a 2.1 system - 35xt's and the 700W. The set sounds awesome, but was hoping to be able to tuck the sub in a corner with it being wireless. Unfortunately, the wireless frequency is 2.4GHz, which is the same as our phone, router, etc. so there was a ton of interference that distorted the sound. Disappointing they would use a common frequency like this.

Pros: great sound, easy setup

Cons: wireless didn't work

Best complimentary for soundbar

Pros:

Cons:

Perfect match for ML VisionX and probably other ML soundbars

Howard from Edwards, CO on 9/16/2017

Crutchfield Customer Review (What's this?)

Adds fundamental bass to soundbars, very musical without breaking the china but can do that too. Perfect fit and essentially "plug and play" with my ML VisionX

Pros: Basically plug, play, and forget it. Built in wireless makes it so versatile in placement and actually reasonable cost.

Cons: Lack of HDMI and ARC but found ARC very temperamental so don't miss it.

Bass-ic Excellence

jeff from Malibu, CA on 7/9/2017

Crutchfield Customer Review (What's this?)

the martin logan product line has a long history of audiophile quality .. this subwoofer follows in that tradition adding accurate bass in the lowest octaves .. set up was simple .. instructions were thorough .. i am using the sub in the radiocontrol mode .. about 35ft away from source .. no problem .. also want to give cudos to the salesman Cody who really helped me put this all together .. shipping was fast and as advertised .. this was my first experience with Crutchfield though i've known of the company for a long time .. as they say in the movies i'll be back ...

Pros: audiophile quality accurate bass to the lowest octaves wireless works well Crutchfield product info and sales support

Cons: none

Great low end and output

Gerald from Brownsburg, IN on 5/18/2017

Crutchfield Customer Review (What's this?)

I wasn't shopping for any new equipment, but then we had a lightning hit... I lost a beloved Klipsch KSW-10D subwoofer. I knew it wouldn't be easy to replace that or easy to be happy with a new item. The MartinLogan Dynamo was one of the few models that I've seen since getting my last sub that impressed me. With a phone call to Crutchfield to double check some things, I was comfortable that this was the right thing for my needs. Set up was easy and quick using the auto EQ of the new receiver in that room. It visually disappears thanks to the very small size and has no trouble at all keeping up with what we ask of it. Great low end and more than enough output for a large room in an 'open' floor plan.

Pros: Small size, wireless is nice, but didn't need to use it. Lots of output. Lots of low end extension.

Cons: Blue LED on the rear is very bright. You'll want to cover that with a small piece of electrical tape.

Small Footprint, Big Sound

Bill from Loveland, CO on 2/24/2017

Crutchfield Customer Review (What's this?)

I purchased this with a set of Martin Logan Motion 15 bookshelf speakers for listening to music only. I am still dialing it in, however the sound is amazing. No problems at all. Only thing I needed to do was add a piece of black tape over the constantly flashing sync light since I am not using the wireless connection.

Packs some punch

biomrl from Clifton, VA on 9/29/2016

Crutchfield Customer Review (What's this?)

Packs a big punch in a small package. Mostly controlled by receiver. Sound is great. Only there when it needs to be. Comes with wireless connection to receiver if needed (I wired it direct). A great compliment to Martin Logan Motion XT60's and Motion XT50.

Pros: Great sound. Wireless connection. Compliments MartinLogan speakers very well.

Cons: None

Martin Logan Dynamo 700w

Frank from West Chester, OH on 5/18/2016

Crutchfield Customer Review (What's this?)

I recently purchased a Yamaha YSP-5600 soundbar to replace a 5.1 speaker system to make better use of the space we have. I then decided I might as well upgrade my subwoofer and was looking for something with a small footprint and that was also wireless. After reading reviews and looking at different brands I decided on the Martin Logan Dynamo 700w. I was not familiar with their products but decided to go ahead with the purchase. After the initial shock of how small the sub was, I did not think that this was such a good idea. Wrong! This puts my old much larger ported sub to shame. The bass is tight and sounds great!

Pros: small size great sound wireless

Cons: none

For being a small subwoofer it sure packs a punch . It brought out the lows that I was missing .great addition to my Martin Logan set up.

Cons: Non

MartinLogan Dynamo 700W subwoofer

LC from Cary, North Carolina on 11/8/2015

Crutchfield Customer Review (What's this?)

I'm still amazed at the sound and power of this subwoofer, from a cube that's about 12x12x12 inches. It can literally rattle the walls (which I did accidentally when first setting up). I've had 2 other subs ( Sony and John Thomas) that couldn't hold a candle to this MartinLogan. It took a little playing around to find the optimal location (thank goodness it's wireless except for the power cord), but I found the sweet spot, so the bass seems to come from the PSB X2Ts I also purchased from Crutchfield. I listen almost exclusively to classical music (specifically baroque), and although the PSB X2Ts have dual 6 1/2 inch woofers, this sub adds a true extra dimension. I highly recommend it.

Pros: Quality of construction and (needless to say) sound that you hear and feel, without making your ears bleed.

Cons: None. I do agree with another review that a piece of electrical tape over the lights would be beneficial (they could serve as night lights).

Great sound, could be more user friendly

RDZ from Pittsburgh, PA on 10/21/2015

Crutchfield Customer Review (What's this?)

Great sound, exceptionally powerful, fantastic companion to Vision soundbar.

Pros: Great sound, awesomely powerful

Cons: Subwoofer shuts itself off when watching tv shows or video at lower volumes. Have to turn volume up on soundbar to turn sub back off. Controls don't make it easy to fine tune settings.

Wireless was a plus especially for the wife who hated wires around. Have heard bass that I had not with a Bose Acoustimass 15. Blended seamlessly with my Martin Logan LX-16 and Motion 8 Center Channel.

Pros: Ease of use and great sound.

Cons: None

Judge Tom from Olney Maryland on 5/18/2014

Crutchfield Customer Review (What's this?)

Wireless feature is outstanding for difficult placement situations..Set up is effortless and they blend in perfectly with two Definitive Technology Studio Monitor 55's in a 12 by 20 ft room with large openings at either end.A larger sub would be superfluous.

Pros: versatile and great value for the money

Cons: none

Concert in the family room

Calvin from Delray Beach, Fl on 4/18/2014

Crutchfield Customer Review (What's this?)

Awesome, I already had a sub and wanted to add a second. I'm using this one in wireless mode, no interference so far. The sound is great, still tweaking the placement and gain. I have it firing downward. Thinking about placing tape over blue light in back. Already I can tell it's the best sub in the house. The only problem was the first sub I got a random thumping noise, I advised Crutchfield and they immediately sent out another. This one worked perfectly. No regrets

Pros: Great addition, I want to say it added warmth to the music. I'm playing a lot of old school R & B, the bass is tight.

Cons: Non, so far

Very Solid Sub, with some minor quirks

Luke from Charlotte, NC on 3/30/2014

Crutchfield Customer Review (What's this?)

This is a very solid and powerful sub. I have it connected through my Martin Logan Motion View sound bar, and the sub delivers quite a punch when it's active. The key word there is active. If the volume on the sound bar is low or you're watching a sitcom or scene with not a lot of bass, the sub does go into stand by mode. And in order to get it active again, you have to turn the sound up in order for it to register. I have not determined whether this is attributed to the sub being connected through a wireless connection versus a direct connection into the sub. Also, there are times the sub doesn't register a signal during a non HD movie (meaning no surround sound). I would think the sub would still come on, but it does not.

Pros: Powerful sound when hooked up Easy to connect via a wireless connection Configuration options to make it fire down or out

Cons: Inconsistently goes in and out of stand by mode During scenes with heavy dialog and no background music or sound, the sub sometimes transmits a tick / popping sound. Don't know if that is because of wireless interference or something else

High-Resolution, Low-Distortion 10" Woofer: The Dynamo 700w's advanced-technology driver pairs a high-power magnet structure with a 10" poly diaphragm to deliver huge excursion and sound output while perfectly preserving the tiniest bass detail; and all without a hint of distortion. The exceptional damping properties of the poly cone material also ensure the smooth, non-resonant response necessary for truly seamless blending with MartinLogan's electrostatic panel and Folded Motion driver technologies found in their loudspeakers.

Inverse Mathematical Equalization (IME) Filtering: An IME filter is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response; far superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.

Sealed Cabinet w/ Internal Bracing: On the outside, the Dynamo 700w's cabinet is constructed from the finest composite material for acoustic integrity. Inside, critically placed structural cross-bracing acts an excellent baffle for the woofer while the added rigidity keeps cabinet-induced resonances and non-linearities to inaudible levels. As a result the MartinLogan Dynamo 700w maintains a smooth, consistent response regardless of music or movie source material.

Front-Firing or Down-Firing Configuration: To maximize performance when installed inside of a cabinet or other discrete installation, the Dynamo 700w's standard down-firing configuration easily converts into a front-firing orientation; no tools required. A grille cover and 90-degree RCA adaptors are provided for use in front-firing applications. Dimensions:

  • Down-Firing Orientation (default): 11.6875" (w) x 12.5625" (h) x 12.875" (d)
  • Front-Firing Orientation: 11.6875" (w) x 13.5" (h) x 12.3125" (d)
Note: If placing the powered subwoofer inside of a cabinet, it is recommended that there be a minimum of 3" of open space between the cabinet and the front and back sides of the powered sub.

Seamless System Integration: Comprehensive connection options, low-pass filtering, and phase control make integrating the Dynamo 700w subwoofer into a multi-channel home theater or stereo music setup simple and seamless. The main left/right line-level inputs feed into a precision low-pass filter with a cut-off frequency variable from 35 to 120 Hz. For systems in which the AV receiver supplies the low-pass crossover, the Dynamo 700w offers an LFE input that bypasses its internal filters. The phase control can be set to 0, 90, or 180-degrees.

Built-in Wireless Receiver: Although correct placement plays a key role in optimizing subwoofer performance, sometimes it imposes the inconvenience of running long lengths of cable through walls, along baseboards, or under floors and carpets. To solve the problem, the Dynamo 700w incorporates a wireless receiver (digital RF transmission) for use with the included SWT-2 MartinLogan Subwoofer Wireless Transmitter which plugs into the subwoofer or LFE output of your home receiver or active soundbar speaker via stereo RCA (cable not included).

Note: You cannot add additional wireless receivers, transmitters, or subwoofers to this system.

Energy Transfer Coupler (ETC) Spikes: The Dynamo 700w comes with custom ETC spikes which can be used along with the pre-installed rubber feet to enhance stability on thick carpets, or create tighter coupling between subwoofer and floor to enhance overall sound quality. The spiked feet add 0.625" of height to the powered sub.

Auto Power On/Off: The powered subwoofer will automatically enter a power saving mode when no audio signal is detected. The subwoofer will automatically come out of power saving mode when an audio signal is detected.

Break-In Period: The Dynamo 700w woofer requires approximately 50 hours of break-in at moderate listening levels before its optimal performance occurs. This will factor in on any critical listening and judgment.

This was a great offer for a replacement sub. My 10-year old sub started rattling on the new Jurassic Park - w/ an offer of 50% off on this MLD 700W, we can get back to shaking the walls and not the old sub's bones. [ Harry  Nov 20, 2018 ]

Already have one and very happy so why not two :) [ JULIUS R  Jun 29, 2018 ]
I don't have a home theater and I use audio equipment only for music listening. My setup employs two Martin Logan 35xt bookshelf speakers. I picked this sub because reviewers have praised it for its tight bass. I listen mainly to classical music and jazz ,and my highest priorities are clarity and detail. The last thing I want is boomy bass. I'm hoping that because it is a Martin Logan product it will blend well with my other ML speakers. [ joel  Feb 09, 2018 ]

5 questions already asked

I'm sorry I don't know. I have ML speakers and the finish on them is incredible. So unless you are very talented or want to have a professional paint them I wouldn't bother. They are like a very expensive piece of furniture. [ Glen  Nov 09, 2017 ]
Disregard the Bose recommendation. The Definitive Technology Prosub 800 in white is a proper recommendation for a powered sub. [ Rodney  Nov 07, 2017 ]
It does not come in white. It can be painted but i would go a different route. I would remove the control panel and woofer, take the cabinet to an automotive shop that does vinyl wrap and have them wrap it. Reinstall the components and put the legs on to configure the woofer in the down firing position. Another option is to go with a white Bose Acoustimass 300. [ Rodney  Nov 07, 2017 ]
I DON'T KNOW ABOUT WHITE BUT I KNOW IT CAN BE PAINTED/JUST SAND IT LIGHTLY WITH VERY FINE SAND PAPER,PROTECT THE DRIVER AND THE CONTROLS AND APPLY 3 LAYERS OR MORE OF SPRAY PAINT /GET GOOD SPRAY PAINT -NO DRIP HI COVERING POWER [ ADRIAN  Nov 06, 2017 ]
If that receiver has either two outputs to right and left or front and rear dedicated to sub woofers.The answer is yes.If it does not have but one sub out then you would have to connect between L and R or Back to front main spkrs and that would possibly interfere with the mains spkrs dynamics.GL,BC [ Bret  Aug 28, 2017 ]

Yes, it has to be wired to the preamp. [ Czeslaw  Jan 04, 2017 ]
Yes, it's a little box that you connect to your pre-outs or sub woofer out and to an 110 outlet. It has a blue pilot light as does the back of the amp/speaker. The unit goes to sleep after a short period of no signal. Actually, I can't tell the difference between this unit and the hard-wired unit I have on another system. [ Steven  Jan 03, 2017 ]
YES.... It plugs into one of the Sub inputs on the receiver. This sub is amazing and needs time to "burn in," meaning after a few weeks of solid use it really comes into it's own! I do wish it weighed more... [ Joel  Jan 03, 2017 ]
Yes, you plug it into the sub pre-out just like you would normally do with the subwoofer. You also need to plug it into an outlet for power. [ Michael  Jan 03, 2017 ]
yes, the transmitter transmits the signal wirelessly to the sub. [ Joshua  Jan 03, 2017 ]
I'm not really sure how to answer this except to say that mine is matched up to a McIntosh MA 5200 and it works just fine, but the room is rather small (14x14 w 10' ceiling) so I don't crank the sub up but a little. [ Steven  Nov 20, 2015 ]
Yo don't. It has a built in amp. You size the sub to the room. [ JEFFREY  Nov 20, 2015 ]
Unfortunately I cannot be of assistance. I purchased my speakers for a move and they are still in the factory packaging. Sorry [ MICHAEL H  Nov 20, 2015 ]
The sub is self powered. You just need to connect to your sub pre amp out or LFE. Also this sub is wireless. [ CALVIN L.  Nov 20, 2015 ]
Since the Dynamo is a powered subwoofer it should not draw off the receiver. I have a 8 year old H/K receiver with 75 watts per channel. I played the Saint-Saens Organ Symphony and there was absolutely no problem. The wood floor literally shook due to the down firing bass driver. It is also great due it is wireless capability with no wires running from the unit, [ Gordon F.  Nov 20, 2015 ]
You can get any receiver. It has gain so you can shape the sound to come in soft for low power or hard for big power. [ BRYAN  Nov 20, 2015 ]
