Hi again, TBers. I'm back a building a new cabinet, but a 2x15 this time. I've learned a lot over my last two projects and plan to apply those to this new one. I was going to use 2 Eminence Kappalite 3015LFs. I modeled it in WinISD and looked at it between 10 and 12 ft^3. At 10ft^3, it stays pretty flat until about 60hz and hitting 40hz at about -4db and about 98SPL at 40hz. It's tuned at 44hz. Of course it seems better at 12ft^3, but that's just way too large. I was wanting it to be no taller than 3.5 feet and 17" or less deep so it would fit in my firebird. I don't know. Any feedback at this point?
