http://www.cerwinvega.com/products/index.html I hope I got the link right . This looks pretty good what do you guys think? It look like its got a built in high pass filter so you can run a 2-10 or something on top of it without the use of an external crossover, that would be nice. I emailed them to get the +/- db rating , they show 32-150 but at +/- what. This looks really good to me but I need more eyes on it to "shoot it down" so to speak. whatcha think? Its the mi series sub 15.
