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.
Summary: Need a little bass in that other rom or at the office? Hey, its small, but well build and actually sounds pretty good with music...if you are looking for a sub with a big presence, this is not the one....but if you are looking to add some elegant bass to a small system, this sub would be a good choice.
Summary: Great sounding, plenty of punch and power. Took a star because it's a bit hard to calibrate and get the sound right. Usually a subwoofer will pair with your system after a good calibration, but I find myself tweeking this thing often to get the sound right. I'd buy another one, but perhaps for a music only system, Movies audio tracks fluctuate too much from title to title.
Summary: This sub is great for the price I paid at $99. Its not going to blow your windows out by any means. Im using it on a 2 channel set up in a small room with line level inputs. It does what I need it to do and thats to fortify the bottom end a little. I have both crossover and level set to just below half. I set it on peice of wood with spikes on its side cross firing to my left. In this config it provides good clean bass. Down firing is not ideal for music.
Summary: This Subwoofer is great if you can manage to get one on sale. At MSRP you are much better off going with an entry level SVS Subwoofer. That being said for the discounted price I paid, the DYNAMO 500 was excellent. The sub is fast, and does well in both music and movies. Yes, it starts to roll off around the 30Hz mark so you will be missing the deep bass. However, gunshots and explosions still come through with authority when the sub is setup correctly.
