Based on internet research I have narrowed down my search to these 2 subwoofers. I have read the specs on each. But can anyone compare and contrast the sound of these 2 subwoofers?

My front speakers are Dynaudio 1.3 MKII bookshelf speakers. And my rears are Dynaudio Audience 52 bookshelf speakers. The fronts and center are driven by an ATI amp...I forget the wattage, but it is a 6 channel amp and I have it bridged to drive all 3 front speakers. My Denon A/V 4300 series receiver drives the rears. The room is 24x15 and has two large openings with no doors. A sub would fit perfectly in the front corner away from the openings. I do have room to move the sub about 3-4 feet away from the wall if necessary.

I want a sub that is musical mainly, but also adds something to my movie watching experience as well.

I am leaning towards the Martin Logan simply because it has an optional wireless transmitter and I know that would please my wife. And there is a local dealer who could come out and help me set it up properly. I have never had a sub and don't know much about setting one up.

However, the wiring is not a deal breaker if I went with the HSU and I understand they have great customer service and could likely walk me through the set up.

Any thoughts? Can anyone who has listened to both compare and contrast?
