2 fi x series 12" d4's high sensitivity subs. they dont need alot of power to get very loud. i sent them 300 - 350 watts rms each in a 4.4 @ 33hz ported box and was definately hitting low 140's. box was firing in cabin. these subs toneality wise sound excellent too. little decay. very fast, and have a nice firm impact.
I will do a ridiculous 190$ shipped for both. they are mint. btw.
