Bottom Line:   
I purchased this subwoofer for two reasons: 1)Sound-It is used in the 2 channel portion of my HT set up and I wanted a sub with very flexible adjustments and very fast and punchy sound. This sub excels at this type of application since it's designed to augment the Martin Logan electostatic panels. I have other subs that are optimized for HT effects so the "big boom" will not be required of this one. 2)Appearance-This sub has a high WAF and I too think that it's one of the the most attractive ones on the market. Since it's used for 2 channel and is out in front between my Vienna Beethovens, apperance was not a small consideration and its hexagonal shape is really a standout. In fact, I think it looks even better than the flagship Descent. Sure, I could have bought something large and square like the SVS Ultra/2, but it's 190 lbs. and just not something I wanted in the living room. As a side note, I did purchase 2 of these but in my room (about 13x20), it was simply too much bass and I returned one figuring it was not necessary to spend an extra $1800 if it was not needed. Although small (approx. 16" wide,deep,and high) and attractive, it is solid and weighs 65 pounds. It feels like it's made from a solid block of Oak. Controls on the back are volume, phase (0,90,180,270), low pass filter (30,35,45,55,65,80Hz), and one unique and handy one-the 25Hz level which allows a boost or cut of a narrow band at 25Hz. This control is really handy if you want to add or subtract a bit of the really low end and was intended to provide flexibility for different rooms. There are 2 high pass filter settings of 40 and 70Hz. There are RCA line level, RCA .1/LFE, and speaker level inputs. There is an RCA sub output for daisy chaining more than one sub. As you can see, the flexibility of inputs and controls is outstanding. The FR is 20-150Hz +/-3db Anechoic so I would guess that with room gain the lower limit will be somewhere around 15 to 17Hz depending on your room (a graph in the stereophile review clearly showed response at 15Hz in the test room using the Velodyne SMS). The sound of this sub is just what I was looking for. Clean, tight, and deep. Although the Vienna Acoustics Beethoven is a fairly full range speaker, the Depth adds much more weight to the music. I have my low pass set at 30Hz and the volume pretty low just to fill in where the Beethovens won't go. Kick drums are more punchy and you will feel them more, rendering a more realistic portrayl of the music. This was something that I felt the Beethovens didn't really do well in my room and they seemed to need the extra horsepower especially for pop/rock. This "punchyness" is one of those things that seem to be greatly helped by that 25Hz control-play with it a bit in your room to get what you want for your taste. Orchestral piecies have gained more weight and pipe organ music is no longer a problem for me. Jazz is extra fine- the speed and precision of the Depth easily keeping up with the fastest bass players on the planet. There seems to be no change to sound of the male human voice, no additional "chestyness", which to me says that the crossover is doing its job well in keeping the upper bass frequencies where they should be. The three woofers in the "balanced force array" do their job very well for mucic and if that is what you are after, then I can recommend this sub without reservation. The seald system and servo control yield a very controlled and precise response. That being said, I have not used this sub for LFE effects so I cannot comment on its performance in that arena. I suspect however that it will do just fine considering the adjustment flexibility. Another note: The "balanced force array" really does work- so far I've noted almost no cabinet vibrations, no matter what is playing and at what levels that I listen at. The woofers are moving like crazy though. Of course, the small and stiff side panels used in the hexagonal shape and the use of rangerboard- supposedly a special MDF only available in Canada must contribute to this brick like non-resonance. In contrast to other conventional subs, almost every one that I've auditioned including my own that I use for HT, has a cabinet that is resonating while playing- some even move around if turned up too much. This might be cool to some people that may think that they're getting a sub that is really putting it out there, but for accuracy and lack of "boominess" that resonance needs to be avoided. There is something else that I noted: The "auto on" feature on my sub works, but it seems to require more of a signal to kick on that my other subs. Not really a problem, but an annoyance when listening at lower levels- such as when playing dinner music. In those situations, I just manually turn it to the "on" position. It should be also noted that I expect performance to improve even more as the unit breaks in more-I don't think that I've reached to 50 hour break in time yet. HAPPY LISTENING!!!

Bottom Line:   
Just picked this sub up last night to compliment my Magnepan 1.6QR's. I was looking at something that would have tight, fast, bass to match my maggies. I have found it in the Depth.

Currently, I am using it in a 2 channel set up, but I will soon be build a dedicated room that will include 5.1 music capabilities as well as a future home theater set up.

I had thought about getting a Rel Stratta III, but after hearing this sub, i knew that it would be a good match with the maggies. The Depth has excellent hook up possibilities for both music and movies.

MartinLogan and Magnepan....a match made in sonic heaven!!

What the guy above said!

This sub is amazing! I have used dual 18" in the past and I can tell you that in no way shape or form did those subs integrate for music! The 18 was too slow and sloppy sounding. The Martin Logan Depth is not like that at all. This thing is fast. I am using two of these for more fill in my room. I had one for about 8 months, but I had a little extra cash so I figured that if one was good two would be better. I am glad to say that in fact two is better. I was able to ease up on both subs to get a bit more volume out of them on SERIOUSLY demanding recordings. I didn't really have a problem before with the Logans, but I have always been a believer in the dual sub setup.
If you like music, you will like the variable crossover and the 4 position phase switch (90 degrees for me, most subs have 0, and 180), the 25hz control is pretty cool as well. That lets you get more floor shaking bass, or less, depending on where you set it. I was a bit sceptical about an 8" driver for a sub, but these drivers look like car audio woofers.

Bottom Line:   
Bought 2 Depths and I am using them with Paradigm Studio 100v.3. All I have to say is no boom and all Punch. If you want bass that hits you like a concrete wall
at a 100Mph then this is it. Solid tight gut-wrenching bass. These are the best subs for music out there. Music comes first for me before Home theater, this is why I choose these subs.
It is hard to explain but they just make the music sound right, it's magical. They do not interfere what so-ever with the midrange or the highs. The Depth is very well controlled 3 8" servo driven woofers
which a big sub just can't compete against
as far as small footprint and SLAM. If you want a world class sub other than spending $30K for the Krell or $10K for the Wilson Watchdog, Martin Logan Subs are the only other game in town Period.
The Depth has excellent controls for dialing in the subs especially a 25HZ control you can adjust -6db to +6db.
