I need help finding specs for the fusion powerplant fpw1200 type subwoofers I know they're old subs which makes it a little hard to find and I don't think I know anyone personally that has a manuel so if by chance you happen to know any info on these subs please share I'm trying to build an enclosure this weekend. Also I see these adds for sub qubed subs anyone know they're performance and sound quality mainly the hs3 and whichever is the step down from hs3
