Martin Logan DYNAMO 1100x

The downside - None to speak of (piano gloss option maybe?). I was shopping for a replacement to my two older (Mirage) ported subwoofers that would compliment my Audiovector QR3 main speakers (powered at 200w RMS each) with more musical accuracy and precision. I was worried that I might require 2 subwoofers or that a sealed sub wouldn't be enough for my 3200 square foot space. WRONG. This sub is tight, accurate, and has WAY more power than I need. Great for music, powerful for theater. My wife had the entire house shaking one night with music alone. Perfectly compliments my Audiovector mains. ARC works very well. This sealed sub really sounds so much better to my ear than ported designs I won't be going back to ported. I can also say that I don't feel the need to have two subs. It also helps that this is manufactured local to me as I do like to support my local economy.

The more, the merrier! Initially buying one 1100X and a 800X just to try out, I ended up buying three more 1100X subs. The primary goal at the time was to create a couple stacks to blend to my Expressions which have a great amount of bass, but I wanted to find out if more woofers would "fill" my large room with more finesse. The short answer is yes! Each Expression now has a pair of 1100X subs stacked about 1" away on the outboard side of each. The bottom with its feet, the top with no feet and a rubber membrane between them for great stability. After a bit of tuning that really wasn't too difficult the result is way better than I expected! I turned down the Bass Control Knob on the Expressions all the way to -10dB which makes the 1100X subs work up to around 90Hz, well, one of them, the other is at a lower setting. Each sub has some unique settings and some settings are shared. I was expecting some improvement in overall feel in the lower bass and maybe more articulation, but there's more. First, at low volume, bass is never shy but is still very accurate sounding. Second, there's way more dynamics with greater impact. Improvement in dynamics is a very welcome and happy result! Music is even more real than before, and presents with greater ease, seemingly effortless, no strain. Finally, the soundstage is slightly wider. Where's the 800X ? At the back of the room. The bottom 1100X of each front stack and the 800X in back are connected together via an outboard controller to create an LFE Group for movies. The input used on each sub is the LFE input. With this group assigned as LFE in the processor, only the .1 LFE is sent to this group, so Bass Management sends the bass below the crossover settings for the Small channels to the Large Fronts. It's a great arrangement! The app helped so much in the tuning phase. What took hours would've taken days otherwise. I truly don't know how I could be more satisfied with the result!

I am very pleased with my decision to obtain a pair of Dynamo 1100X subs to augment my Motion 40i speakers. After some occasional tweaking over a period of a couple of months, I feel I have them set up to my satisfaction. The 1100X is an excellent value that won't disappoint.

I was looking high quality sub to add Kef ls50 wireless without spoiling image of kef sound and my intention to use only for movies or some times for music listening if i want feel like concert like big bold sound. I knew, needed something like room correction sub and app control required as i had experience with other brand room correction sub. So i tried Dynamo 800x from audio advice. i left with great disappointment after playing while with different settings, Mobile ARC nothing worked out . there was huge vibration on floor ( wood carpet 1st floor ) without out tight musical bass and feel in my gut . if i increase volume it sounded like ported sub woofer especially with movies . Even i waited for 3 weeks for break in period and no significant improvements . so i decided to try 1100x , gland i did. exactly this is the what my expectation were in my mind, when was searching sub woofer . With 1100x i am able to hear difference in bass musicality. Sound is very very musical with fast thump feel in my gut, big and dynamic tight bass even at moderate main volume of Kef without any vibration on floor (80hz crossover and -14 db sub with Mobile ARC ) . I saw The Ritual, quiet place, The Greatest show man trough app tv , All theses sounded great especially in ritual movie after they enter forest , there was thunder sound and that sound almost reaches near to life-like real thunder sound. From this experience i can strongly recommend that do not go for 800x and just go for 1100x there is a huge step up between 800x and 1100X. i can say simply 1100x performance matches the production description what ever they mentioned.
