Crystal CMP 12

Price Paid:  $250.00 from Carmedia1

Strengths:
great sub, plays loud and clean from 30-60hz.. no sign of distortion or unresponsiveness. small box design.

Weaknesses:
Doesn't play upper bass 60hz+ as well as lows... but after all, it IS a SUBwoofer. Wouldn't mind more SPL for my tastes but i'll have to try it ported. Sub is a bit inefficient but expected being a small box sub.

Summary:
Wow.. great sub. This is the best SQ from a sub I've owned.. (JL W6, W0, W1, DD9512, MTX, Orion XTR). SPL is best around 40hz, too bad my electrical system is currently stock and cd player skips from the bass. Currently running 2 sealed off a linear power 3.2hv and I'd estimate its spl around 138db before it skips the cd player and dims my lights. Sub is tight and accurate. It does not "boom" and bass isn't muddy or slow in response. You can probably expect ~140db from 2 of these sealed.. 142db ported. Specs show these best ported so I'll have to build another box to try that. Not too satisfied with bass below 30hz but none of my music really gets that low.
