[QUOTE="Art Welter, post: 146358, member: 52"] Re: No compromises front loaded double 18” cab John, Generally bass reflex subs do not use insulation inside, as it cuts output level down, and since subs are low-passed, there are no upper frequencies coming out of the ports needing to be absorbed. Wire should be stranded 14 AGW (or thicker) and tied to the speaker frame and stapled to the cabinet interior to avoid flex failure and rattling. I prefer to use speaker cloth stretched over a plywood frame, Evan is using perforated steel with an expanded foam backing. Art [/QUOTE]
