all these idiots stating its no good,or cant handle 90 watts? etc dont know what there doing. ive been a long time audiophile about 6-7 years now, i very much so know about everying there is to know about subwoofers. this woofer is great, not a competition grade but will bang good. in a 2.0cu ft sealed or 32hz tuned ported it will sound its prime.i have had it on about 300-350rms and it seems just dandy. gets a bit warm but its normal. DVC 4ohm easily wires down to 2ohms, coil is 2.5″ the only downfall i see from this woofer is its excursion abilitys. it doesnt move very far without actually bottoming it out id presume, the rubber surround is very un beefy and the spider is the biggest dissapoontment, its spider is that of the size from a typicall 12″ subwoofer. either way, i baught two of them so far. ill keep coming back untill i have all 6 of the 15’s by SSL. VERY pleased overall for the price-perfomance ratio. best ull get in the audio world within a $50 price range,unless a used item off craigslist perhaps. two pictures uploaded are by me.
