Dynamo subwoofers pack an incredible feature list and impressive power into a stylish, compact, room friendly package. With extensive technology including built-in wireless signal connection, anti-vibration feet, and easy to use app control, Dynamo series subwoofers not only look and sound incredible, but are extremely user friendly. 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, Dynamo 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. The integrated anti-vibration feet 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, the integrated anti-vibration feet on Dynamo Series subwoofers 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. Dynamo Series 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, Dynamo Series 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, the Dynamo Series is designed to work with any speaker system while also being uniquely engineered to keep pace with the renowned clarity of MartinLogan loudspeakers. Dynamo Series subwoofers offer highly detailed and powerful bass performance in a stylish and compact package.

KEF’s Music Integrity Engine is a proprietary suite of in-house written DSP (Digital Signal Processing) algorithms, serving as the mastermind behind the detailed and accurate sound that characterises our wireless speakers and subwoofers. Kube delivers more depth, greater output and increased dynamics than ever.

This subwoofer exceeded my expectations. The bass is deep and punchy without overwhelming the rest of the soundstage. Setup was quick and seamless, and the build quality is top-tier. It looks great in my setup and performs even better. Worth every penny.

This subwoofer replaced a REL T7X which I liked but did not provide the same tight, deep bass this does for 2-channel music or home theatre. It also integrates more seemlessly with KEF main speakers.

The KEF KC 92 is an excellent subwoofer. After doing market research and analysis, it was highly recommended by many audiophile reviewers. After listening to it and using its with my audiophile system, it has lived up to its reputation. KEF has hit it out of the park one more time. Nice job on superior performance and workmanship. Very highly recommended.
