I have a pair for 10 years (already!)
There are two months I did a little their facelift: removing carpets, sanding, painting installation of wheels, corners ... And above all change the amplification on the advice of a PRO, I pushed in crest or QSC (2x600 in 8) now a PLX2402 bridg 2400W at 4, I redcouvre (and again, we can do even better with the big amps "very" high end, too chre for me ...) !!!!
In short, super subwoofer lasting, lasting, lasting if one cares BUT as many will say, prvoir a large amplification quality !!! so expensive ... Good advice, forget mactruc, audiomachin, etc ...
It is heavy trs! It should be what to you say, but it's a breeze kidney: prvoyez really smoothly, matter of survival! Another word, the bass is deep, dynamic, round. The sub is equipped with a impressive crossover for use active or passive combines a head (with enclosure gnial SERIES wind, eg 1000.). The comuter is simply an inter ct of Speakon.
