Summary: Asides the fact that this is a very good looking subwoofer I am fairly pleased with it. This won't rock your socks off. If you are looking to blow your head away with bass then steer clear. This sub does a great job supplementing my speakers and hitting those low freqs. It is however only an 8 inch sub, that comes with limitations. To me this sub has a musical quality to the bass it produces. I like it.
Summary: I bought these to pair with a set of Vanatoo Transparent ones, which aren't absent of bass but after years of using JBL S310s (3 way floor standing speakers) which migrated to the living room, I needed something to fill the void. I own a 10 inch Polk Audio PSW10 which decent for the price but not quite a 5 star rating. Despite the MartinLogan being a smaller woofer, the Martin Logan hits deeper, and has the advantage of tighter response.
