    This sub woofer blows away my B&W that I absolutely loved. The new efficient technology including the App makes this Sub a great value for under $1000.00.

    Absolutely shocking performance for a Sub this small. The set up was a breeze using the TWO provided apps. One runs the Sub, the other (ARC) completes the room correction feature which had a HUGE impact on the units integration to my system. I've had many Sub's, have three theater set ups and this one is by far the best.

    Amazing sound and build quality! The actual woofer itself is absolutely beautiful! A true work of art. Very small but packs a punch. I love it.

    This thing is incredible for the size. And to think, it’s supposed to improve over 50 hr break in period. Love to hear the bigger ones. Might have to add a second sub!

    My current set of Infinity speakers are great on the high end but a bit weak at the bottom. I finally got around to setting up a sub-woofer and it rounds things out nicely. Still in the recommended "break-in" period so I have tried to blow out the windows yet.

    The bass’s sounds so good during action movies . Easy to set up. There’s an app that you can connect to Bluetooth and you can easily calibrate it as well as tweak the DB to your liking without messing around with the receiver

    Hits hard if you need it to for theater, very musical which is personally more important to me. Like the ability to turn up/down with my phone.

    This is my 2nd MartinLogan Dynamo 800X. I bought it to supplement the 1st one so that the bass will be "felt" more evenly throughout the room. It is doing just that. I'm very satisfied with the product.

    The subwoofer that I got to go with the Bowers & Wilkins bookshelf set. I looked at the b&w subwoofers, both the 600 and the 800 but decided to go with the Martin Logan for the crispness. Love the combo.

    Great sub. Although the salespeople didn't tell me that to use the bluetooth. It required a device. Which is another $200, that I had to order. The device that gives you the ability to adjust the volume ,EQ , and all the other settings. Settings that make this subwoofer really shine.
