ok i bought these subs as a temporary solution until i got my eclipse titaniums. i was prettty pleased with them. i had them hooked to a sony 1200wat mono at 600watx1@2ohms, in a 1.3cu' sealed box, i was hittin low 140's, bass was deep and tight, pretty responsive to, my freinds at my local stereo shop were quite suprised by them, for 55 bucks its not a bad investment. but no where near my eclipse's
