if i had done my 1508s up or to the rear i think i would have picked up about 1db or so.i'm in a truck, so things may be a little different...
x2 I sent you the dimensions of an L port box that works well with those 10's. Hopefully it helps.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gifIt all going to come down to the install.
You are not even talkign about the same sub the OP is, SOLO X not L7 dumass.Havent heard a DD before, but I have heard an L7 so I really couldnt help. But if there both just SPL there shouldnt be much different
