i have an RE audio XXX 18 that was once a 12 and i had rebuilt to an 18 a few months ago. got a FI BTL 18 now so XXX needs to go. askin 500
rms is 1600 but it can take a lil more. i had about 1600-1800 rms on it.
i had it in a 7.5 net internal cuft box tuned to 31 hz and it was amazing. did 143.5 at 30 hz on my TL.
to compare it to the BTL the btl is louder but the XXX sounded way better.
im askin 500 cuz the sub has cost me about 600 so far. i will admit that it has a couple of scratches on the surround. no affect on the sound or output.
i also have 2 IDMAX 12's D2 235 shipped a peice.
one was a display sub in a store so the cone is a lil faded. sounds great though. the other is at ID getting reconed so it will be a brand new sub when i get it back.
