[QUOTE="LuNaTiC, post: 1354830, member: 548925"] 1. A second woofer is added to an enclosure for a total of 2 woofers. Alignment is optimized to perform with the second woofer It wouldn't be 6 db increase.. 1 sub is in a box, you add another sub in the same box. The box happens to be optimized to perform with the second sub. Assume the subs are exactly the same. The box is optimized for the second sub, therefore isnt optimized for both which can drastically decrease output compared to a box optimized for [B]BOTH[/B] subs. See what im trying to say? its hard to explain. 2. A second speaker is added to the listening environment playing the same information as the first this one seems like it would be acoustically doubled or 3db increase [B]ASSUMING[/B] by information the sub is getting the same power also.
