[QUOTE="Iso187, post: 2795521, member: 575248"] I previosuly had my 2 12" Perfects in a 1.88 sealed box(each), then later (to free up some space in my trunk) decided to build Decware's infamous DeathboxII. I was VERY impressed with the deathbox 10, so I guessed the 12" version would have twice the output. The key is I want to use BOTH the woofers. I iso'ed them in the Deathbox (yes, wired correctly) and... sounded very nice and clean, but greatly lacked the SPL that the previously sealed enclosure had. As a last resourt I would go to a ported due to the large volume needed. I understand the SS is also a large enclosure, but if it is supposed to have the sound quality of a sealed, w/ the output of a vented, I am willing to test it out first. But as previously stated, I would like to use BOTH the woofers.
