Customer Ratings & Reviews

Replaced a Dynamo 500 that I played into the ground. The 600X is a great upgrade for my system.

Great sound! Just what I needed as I wanted to hear bass when the volume was turned down low.

The subwoofer was easy to set up. You can feel the vibrations on the floor. Action scenes are more intense.

Pieced this together for our living room amd couldnt be happier. I want to buy another one for the opposite corner of our living room

I purchased this subwoofer with one of their center channels as an upgrade to my franken system. I have mirage Nano as my rear surrounds also mirage subwoofer and pioneer elite Dolby atmos for the fronts. I have to say it really changed the sound of my system. I am happy.

This sub has great sound quality. Tight controlled bass with detailed musicality. This would work very nicely in a small home theater room, but falls short on presence and impact during movies in a medium/large room (24ft by 16ft). Recommend for music listening at lower volumes, but unable to keep up with power from Yamaha aventage reciever (drowns out subwoofer)

Easy setup with the app and has a great sound for the price.

Great bass sound! I use this as a 2nd sub with my system and am very pleased with the results.

Bought this for room that has three walls and has a full kitchen behind it. I read reviews that this sub was better for smaller rooms but I bought it anyway because my wife can’t handle over the top bass. I seem to have got the exact middle ground I needed. She hasn’t complained about the house shaking and I get a fuller sound when watching action movies

Amazing sub ! Great for music but definitely didnt disappoint with movies either

I've been wanting to enhance my home theater for a while and I finally got what I need to do so. These Martin Logan speaker systems from Best Buy are awesome. Thanks Best Buy!

Excellent Dynamo Subwoofer that replace my Bose subwoofer.

This subwoofer sounds amazing! I purchased two of them for my theater and I am extremely satisfied with the sound. Would highly recommend!

This an amazing subwoofer and I love it sounds. I love the way it sounds when movies are on.

Sound is awesome,easy adjustment,for more base sound

This is a high quality, well-made speaker. It’s the perfect subwoofer for a small to medium size living room. I live in a townhome, and the bass this subwoofer produces is exceptional for my 300 sq. feet living room. This subwoofer is replacing an old 10inch sub that was part of a pre-packaged surround sound system. The old subwoofer produced good base, but nothing like this MartinLogan sub. Both have 10-inch speakers, but the Dynamo 600X can produce lows down to the 27 Hz frequency. At that frequency, you hear and feel the rumbles in movie explosion scenes. And it’s not a harsh or bloated rumble; it’s a smooth and clean sound. The 120 watts RMS output is also the perfect amount for my size living room. It’s powerful enough to produce loud base, but not too powerful to shake all the houses next to me. The setup is quite easy. I ran the single subwoofer coaxial cable from A/V receiver to the back of the LFE input on the subwoofer. There are other methods to connect the sub, such as with standard left and right RCA cables, or with speaker cable that are terminated with banana plugs. Either way, you should have this sub up and running in no time. At this point, the base and low frequency sounds are exceptional, but if you want to fine-tune it further, MartinLogan offers a free app that you can download to either your Android or iPhone. The app connects to the subwoofer via Bluetooth. Once connected, you can adjust the sub’s volume, phase, polarity, etc. It’s not necessary to do all this, but the options are there if needed. The most useful feature in the app is the Sweep option. When you activate the Sweep option, the sub will begin producing base at its lowest frequency level (27 Hz) and slowly increase the frequency to it’s highest base level (200 Hz). Not only does it sound cool, among other benefits, it’s also very helpful in allowing you to determine the sub’s best volume level for your room. One more point regarding the setup, in addition to the subwoofer’s app, MartinLogin also integrates something called Anthem Room Correction, or ARC for short. Using a separate free app, you can fine tune the sub further by allowing your phone to use its built-in microphones to measure the sub’s soundwaves in relation to your primary seating areas in your living room. Essentially, the ARC app measures the sound using algorithms, and improves the sub’s output based on its location within your room’s unique dimensions. This process sounds complicated, but MartinLogin makes it very easy to use. They also provide these options for free, which is a testament to MartinLogin’s passion for sound, along with their ability to stay up to date with the latest technology. I do want to mention a few limitations. However, they were not deal breakers for me. I wish this model had the Energy Transfer Coupler spikes under the rubber feet. The rubber feet do an excellent job keeping the sub stable, but the spikes would have secured it in-place better. Also, this unit’s speaker is only down firing. While this will work for most people, MartinLogin’s higher models allow you to convert the speaker to forward facing if needed (for when it’s sitting behind a cabinet). One more major difference in design between this model and MartinLogan’s higher models, the LFE and Right RCA plug share the same input. Meaning, you can either use the standard RCA (red & white) stereo cables to connect the sub to the receiver, or the single subwoofer coaxial cable, but not both. Again, for most people, including myself, this isn’t a problem. But others may want to keep their stereo inputs separate from their home theater multi-channel LFE input, to allow for even more control of the subwoofer. Overall, I’m very satisfied with this model. If you’re looking for a quality subwoofer with the latest technology, the Dynamo X series is the way to go.

This excellent speaker is part of our home theater. Pleased with sound quality and performance so far.

Another great product from Martin Logan. I am glad I added this to my surround sound system.

my old DCM powered amp finally failed, this was a replacement and works nicely into my current system

with just this woofer - didn't have to change the other speakers, and the system sounds much better.
