[QUOTE="Lightninghoof, post: 2993819, member: 569919"] It's a common chamber, 5CF net. (2.5CF net per driver) Stuffed with fiberfill, I estimate effective volume to be 6CF (3CF per driver) Most users would prefer a smaller sealed enclosure for a pair of 12" drivers due to size constraints, but the larger the enclosure, the lower these drivers drop and the better the efficiency. I would much rather have to make EQ cuts to flatten the FR than to have to make EQ boosts due to an overly small enclosure. For reference, .707 Qtc (butterworth) alignment requires 3.12CF for the 2007 model. (SWX-1243D) I wouldn't recommend an overly small enclosure for these. [/QUOTE]
