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.

Relish the immersive audio experience created by this Klipsch Reference II subwoofer. The spun-copper injection-molded-graphite subwoofer and built-in digital amplifier provide high-volume bass free of distortion, while its 29 to 120Hz frequency response lets you enjoy an extensive range of sound. The 12-inch height and brushed polymer-veneer finish on this 400W Klipsch Reference II subwoofer enhance the look of your entertainment setup.

The all new 9x has even greater output than before, but the headline news is the way it sacrifices nothing in clarity and transparency to achieve this. At this price it opens the pathway for owners of high performance European floor and stand mounted monitors and smaller panel speakers to enjoy truly full range sound.

I love this subwoofer! I didn’t want to run cables to the back of my room where I decided to place the sub, so I got the wireless kit Rel Model:HT-Air MKII SKU:6560282. Extremely simple setup. Creates its own wireless connection. Comes with everything you need. You just need power outlets to plug into near your receiver and also where you decide to place your sub. If the placement of the sub is close enough to your receiver, you just need a power outlet and an RCA cable to go from the receiver to the sub. No wireless kit required. I upgraded my RCA’s to Audioquest Black Labs. I wanted to reduce as much unwanted noise as possible. Sealed system provides beautiful clean punch and rumble while watching movies, and is extremely tight when listening to uncompressed audio 2.1. I can’t imagine anyone being unsatisfied with this sub. After accommodating for my specific room acoustics, I have it dialed back to 40%. You will not be disappointed.

Upgraded system with 1st sub, after upgrading AVR earlier in the year that accommodated 9.4 After about 40 year old HK system that still works great at 4.0, So obviously a major upgrade. Rell sub was recommended by several Best Buy experts and glad went higher end. Sub sounds awesome, did need to adjust AVR settings a bit, boosted base too much so tuned it as needed on AVR settings for a great blend of new base range. Music and Movies all sound much better. Old system is great for game room, but no going back from 9.1, except forward to a 2nd sub in the future, and some updated speakers.

REL specializes in subwoofers and it shows. They are great for both movies abs music. They are in a sealed enclosure witch gives them a tighter sound while remaining quite powerful. I’ve been into audio equipment fir 50 years and i have to say the REL subs are inw if the most impressive components I’ve ever cone across.
