[QUOTE="RandyJ, post: 1590936, member: 557626"] Well what about the filters are you wondering? A subsonic is simply like a super low filter. When you have a ported enclosure, low notes can cause your drive to over exzurt(sp?) itself, causing serious supension damage, and possibly bashing the former on the pole piece, intern ruining your speaker. You set it about 5Hz below tuning, and then don't have to worry about anything. Some manufacturers may use sub and infra together, so let us knwo what manufacturer you're looking at. [/QUOTE]
