Descent i

Ultimate Bass

Three 10-inch drivers, leading-edge technology and a unique force-canceling driver configuration yield deep, powerful, yet controlled bass that perfectly complements all speakers.

Building on the groundbreaking technology of the original Descent, the Descent i incorporates new features and enhancements that simplify system integration while improving performance. Its signature three-driver, force-canceling configuration virtually eliminates bass-blurring cabinet resonance. And each rugged, custom-built aluminum-cone driver is servo-locked to its own sophisticated, high-power amplifier. The result is dynamic, unrestrained output to the very lowest frequencies, yet with clarity and definition approaching that of electrostatic transducers.

Launched in 2007

MartinLogan Descent i Subwoofer Reviewed

"The Descent i improves upon its formidable predecessor and is an excellent subwoofer. I was particularly impressed with its flexibility and musicality. The subwoofers connection options will allow easy integration of one or more subwoofers into either dedicated stereo systems, home theater systems or both"

New Dynamic for Large Entertainment Room
Replacing our old subwoofer with the Descent i has created a whole new dynamic to our 9.2 channel Home Theater. The room has 19 ft. ceilings and is aprox. 750 sq. ft. in size. Adding the Martin Logan subs has finally brought us the sound and feel we have been searching for. I work from home and listen to music most of the day and find the sound to be very clean and pleasing in adjacent rooms. All our guests agree that the movie experience is outstanding when watching Blu-ray action adventure films.

Truly awesome.
I have had my Descent i for six months now and am astonished by the sound quality. With mutichannel SACDs everything is very realistic from Dave Brubeck to Pink Floyd. Musically this sub is near perfect as each signal response is so accurate. I use LFE only and set at 90 degrees phase, 25hz at +4,50hz at +4.9, level at 7 and low pass at 45. I set it up as online instructions and broke it in on low level for a week before final adjustments were made. At this setting I can find no fault in sound quality. Movies and video games are also fantastic. I have 7.2 surround and have a Martin Logan Abyss for my front sub with the Descent i shaking up the rear. I no longer miss any hz level of bass and sub-bass. I have fallen in love with Martin Logan speakers and am now trying to save up for a pair of Summit X. It seems I need them now.

Summit X with two descents
Recently added first one then a second descent sub to a stereo only system. I know that conventional thinking is that this is probably overkill however not for me. I find that the low bass without them although very very good still lacked the higher impact that I craved. I was concerned that in the search for more bass that I would smear the very high quality sound from the Summits.......... I have had over time 3 or 4 different manufacturers of high quality subs. The descent i is without question the best. These produce solid, tight and low bass that until you hear them in your favorite tunes you are missing part of the musical experience. I really like the out-of-box thinking that went into this unique design. Many times unique does not equate to superior but it does here! After several tries settled with crossover at 45Hz with one sub in line with the Summits and one 8' away along the adjacent wall at 90deg. ...no the subs did not smear the sound from the Summits but improved upon it.

My Descent i
Can your subwoofer levels go to 11? As they say, ours does! It's an awesome sub and it really opens up and boom when it's time. Can be fine tuned to your needs. It never ceases to amaze me how each movie sounds are so distinct.

Excellent product
This is a wonderful sounding, fast acting sub. I loved it so much that I purchased three for my home theater system. One of my panels broke and their customer service group sent me replacement panels at no charge. Great group of people and great product. I wish I had this quality of customer service with the rest of my components.
