I'll have to agree with Mr Grubbs, and Oldschool4me. I have a pair of JBL GTi MK II's that will be going into a 1cft sealed/ea enclosure. However, the guy that talked me into the JBL's was a sealed fan, and tried this sub ported. He said he was blown away. He had never before heard a sub in a ported enclosure that sounded as good as sealed, but he said this one does. I'm still going sealed, but I'll be running 1200w to each. I think that should take care of the low end extension. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
I just prefer the 1 cft enclosure to the 2.25 cft encosure. I still want SOME cargo room! Now, that's for the 12" The Gti 15" only needs 1.5 sealed, but 4 cft for ported. The price is in the range you asked for, and the power handling is good to 1000w as well.
