Looking at using four of these im my Expedition, around 6 cubic feet vented tuned to 26-30Hz. They look great in WinISD to me, does anyone else mind modeling them for me to see if I am missing anything? Only planning on around 150-200 per driver, hoping to do decent day to day spl at low frequencies with good sound quality. The price is great on these drivers right now... I actually considered using 8 sealed, but the 4 ported had better response and output!
