MartinLogan Abyss Subwoofer

"The great thing about the Abyss is that if you do set it higher, you won’t be forced to suffer higher levels of distortion, because MartinLogan has managed to keep distortion very low, so rather than hearing woolly, indistinct bass, you hear clean, incisive bass notes, and when there are several bass instruments playing together, you’ll be able to hear each instrument quite clearly— the sounds don’t collapse together into an amorphous ‘mass’ of sound."

MartinLogan Feature powered speaker and Abyss subwoofer

"The Abyss easily kept up with the quintet of Features. On my reference mothership flyover - the opening of Star Wars: Episode II - Attack of the Clones - it reproduced the spaceship's deep rumbling with no audible trace of distortion. Even many much larger subs struggle with this passage."

—Brent Butterworth, Sound and Vision

MartinLogan Feature powered speaker and Abyss subwoofer

"Used on its own or with the company's Abyss subwoofer, Martin Logan's Feature speaker brings a new excitement to on-wall audio...audiophiles will probably prefer this system to any other on-wall rig - both because of its sound quality and because it's an original and exotic take on what has become a predictable product category."

Why did I wait this long???
Just received my ML Abyss sub today, along with a new high end power cable, and all I can say is WOW!!! Why did I wait so long to buy this. Bass is tight, fast and deep, all in such a small footprint...I'm amazed. Build quality is top notch, detachable IEC power cable a huge plus and the design of the reversible cabinet just amazes me. Why aren't all subs designed this way??? I bought to replace a $2000 15" Velodyne Servo sub (one of the highest rated subs of our time)that was just too big for my new room. I was afraid that I would lose too much performance by replacing, but this sub fits the bill perfectly. Sure, the Velo plays deeper, but the Abyss is right behind it, and it looks MUCH prettier. Can't wait until it's broken in so I can see what this sub can really do...I'm sure I'll be even more impressed. I have a feeling my Klipsch Reference speak's will be soon replaced by some new ML's...LOL!!! That's how impressed I am with this sub. Run and get one while you still can...

Great Sub - very tight bass
Love this product. All I have is a 5.1 set up for my HT room and this sub does the job. Found it at Fry's on a clearance sale and I could not have been happier. Clean, crisp bass even when pushed a little. No distortion. Not the loud thumping bass from cheap Subs ...Overall very happy.
