Summary: Absolutely amazing! I purchased this with the Martin Logan Motion 8 Center Channel. I am going to replace the reset of my speakers with Martin Logan's. Even with the high expectations I started out with due to the reviews and price points I was extremely impressed.
Summary: I initially got a good price on the subwoofer, unfortunately it had an intermittent thumping noise and has to return it to the vendor. I had to pay for the return of the item which put me at MSRP for the item. I received my replacement subwoofer and it works fine.
Summary: This sub was very underwhelming. If you have a large space DO NOT BUY THIS. I though if I bought 2 it might fill the space and I had no such luck. To turn them up high enough to get any reasonable bass they were so high they were distorting.
Summary: All of my equipment is Martin Logan as I've never had any problems with them. Just an FYI, this sub is tiny. It packs a great punch but really is small. I'm very happy with it and it also came with the wireless transmitter as well.
Summary: This little sub (and it is tiny by sub standards) is wirelessly paired with a MartinLogan Motion Vision Soundbar. With the sub's volume knob set at 50% and the soundbar set at about 80% of its max volume, the sub is bottoming out and literally bouncing itself around.
Summary: All I was hoping for...I'm no expert and have not performed a spectrum analysis at peak current. It produces wonderful bass across a selectable frequency range and gain. Should put a carpet under it; the vibration makes it slides around on the hard wood floor. Be sure to use a grounded cable.
