MartinLogan - Abyss 10, 10” Hybrid, Powered Subwoofer, with Magnitude MT-1.6kW Amplifier, Sub Control App, and Wireless Built-In - Gloss Black
5.0(1)

Abyss Series subwoofers offer a twist on traditional subwoofer design. Combining the enhanced output of a ported sub, with the smaller footprint and natural sound of a sealed sub, MartinLogan’s Hybrid Woofer System allows Abyss models to offer the best of both worlds. Packing an incredible feature list and impressive power into a stylish, super-compact, room friendly design, Abyss subwoofers deliver performance completely unexpected from their size. With technologies including built-in wireless signal connection, anti-vibration feet, and easy to use app control, Abyss Series subwoofers not only look and sound incredible, but are extremely user friendly. Abyss subwoofers utilize a Hybrid Woofer System, which pairs two custom designed, aluminum passive radiators with its active aluminum woofer. This driver layout provides the increased output and lower distortion of a ported design, while maintaining the more compact sizing, and tighter bass typically associated with a sealed design. While much more difficult to design and engineer, this Hybrid system gives Abyss Series subwoofers the benefits of both sealed and ported designs all in one. Utilizing state-of-the-art Klippel analysis, these proprietary Aluminum drivers are specially engineered for high output and low distortion. Aluminum, chosen for its low weight, high strength, and excellent heat dissipation, is ideal for the big power and small size of Abyss Series subwoofers. Although correct placement plays a key role in optimizing subwoofer performance, getting a cable where you need it can be challenging. With the inconvenience of running long lengths of cable through walls, along baseboards or under floors and carpets, properly concealing the subwoofer cable is not always a simple task. To solve the problem, Abyss Series subwoofers incorporate a built-in Wireless Receiver for use with the included Wireless Subwoofer Transmitter. With quick and easy setup thanks to direct pairing, eliminating cable clutter has never been easier and with lossless transmission and low latency, even the most discerning enthusiast will be thrilled with the results. Solid bass performance is a critical component of any audio system, and helps provide visceral impact to your entertainment. Abyss subwoofers use integrated anti-vibration feet to improve bass performance while reducing floor and wall vibrations. By dramatically reducing the energy transfer between the subwoofer and the floor, unwanted room rattles and buzzes are removed, leaving tighter, cleaner bass and improved system clarity and dynamics. As a less intrusive alternative to acoustic room treatments, these integrated anti-vibration feet can also help minimize noise complaints by reducing vibration transfers into adjoining rooms. Ideal for all floors, hard surface and carpet spike options are both included. Abyss subwoofers also take advantage of MartinLogan’s Subwoofer Control app for iOS and Android devices, allowing you to easily adjust settings like Volume, DSP Mode, Phase, and many others right from the comfort of your seat for ultimate control and ease of tuning. With 3 DSP modes for Movies, Music, or Night, you can optimize the performance of your subwoofer with a single press in the app. Choose Movie for the highest output, Music for lowest distortion, or Night to tame things down and help reduce noise complaints. With connections for both RCA and XLR LFE, Stereo RCA, and Speaker level, Abyss subwoofers are an ideal choice for both Home Theater and Music applications, integrating seamlessly into any system. The Subwoofer Out connection also makes it easy to add additional subwoofers to your system, further increasing bass performance. As with all MartinLogan subwoofers, Abyss models are designed to work with any speaker system while also being uniquely engineered to keep pace with the renowned clarity of MartinLogan loudspeakers. The high output, low distortion Hybrid Woofer System paired with the power and precision of MartinLogan’s Ultra High Resolution Vojtko DSP Engine, and Magnitude series amplifiers provides a recipe for highly detailed and powerful bass performance in a stylish and super-compact package.

Dynamo subwoofers pack an incredible feature list and impressive power into a stylish, compact, room friendly package.

  • Rated 5 out of 5 stars

    Absolutely amazing!!

    I bought a pair of these for use in a dual purpose HT/two channel audio system. They are running master/slave. I also got the PBK kit to tune them to the room. You need two of these kits if you’re running the subs in left and right mode, but if you daisychain them it requires only one. My room is 15 foot wide by 30 foot deep. After about a 60 hour break in period i was amazed.  I also auditioned the SVS ultra 16 which was another amazing sub pair, if I was going for pure SPL and ultra low extension for movies only I would’ve chosen them.  The Logans have enough power to completely pressurize my room, and when required they can go very deep. The specifications say it can play down to 20 Hz and in my room they do that. The winning attribute for the Logans was the pitch, definition, and insane quickness. It’s possibly the most musical and fast transitioning subwoofer I’ve ever heard. There is a huge difference between loud powerful bass and perfectly articulate bass. It can transition between a 25hz thunderclap to a 60-80hz drum with insane speed and realism. When properly tuned the subwoofers completely disappear in the room. Low bass seems like it emanates from everywhere, and drums sound like they hover in between the front speakers. The only thing to take into account with these aside from their price point is room placement. You definitely have to get them in just the right spot to have them sound perfect. The Pbk kit can help but placing the subwoofers correctly is important for these guys. I have them paired with Bowers 702S2 being run by a Mcintosh amp. They blend perfectly. I highly recommend these, or if you want a little more extension and a little more SPL and have the room the 12 inch version of these are a noticeable step up. Hope this helps
