I would have to disagree, I have the Polk PSW 404 and I love it. I got it through the scratch and dent through crutchfield , so i got a good deal. Now don't get me wrong those subs mentioned here are a good sub... I chose polk cuz the rest of my speakers are Polk... on the other hand my dream sub would be the Paradigm signature servo

...just so i can rattle my apartment apart.. they junk anyway
