Well I was thinking of getting an 18" sub, specifically the 18" Fi BL, but I was wondering would a 15" Audiopulse Revo be louder, under perfect conditions for each of them? I'm looking for max SPL.
Sorry for double post. How good are the 18" HDC3's compared to an Fi BL? Also, still lookin for who makes the DD's, and how are those compared to the HDC3's.
