u.s. acustics any good?

so i was looking at some 12" subs buy u.s. acustics but i dont know if they are a alright brand. so my question is, are they? i was going to hook them up to a r.f. amp if that makes any differace.

US Acoustics makes subs now?

eh...I'd stay away personally, a couple of their amps are alright, a couple of them are worthless trash, I wouldn't take the gamble on their subs without hearing a LOT of opinions first
