bandpass boxes have their chambers in front of the woofers and i dont think its ported on the back they usually port on the top or front looks like sealed with a plexi window. Also make sure that is thick plexi otherwise it will flex and cause lost spl and such.
yeah, that doesn't look like a band pass... the subs them self are usually 'inside' the box with a sealed chamber infront of them, then ports on the top or front, i think you could find a better deal on that, it's basicly a sealed box... even if it has ports in the back... probably not worth it.
doesnt it look like a pro box? it has double 3/4 MDF and corbon fiber front. umm so i shouldnt buy it? i want more bass then my bandpass puts out. the bandpass only play one note. u guys should save the pic and enlarge it to see the carbon fiber front
hmmm i was thinking of putting the jl subs back in the bandpass box and wiring them to 2 Ohms and adding a 12" jbl gt in a ported box at 4Ohms. so one channel is gonna be 2ohms and the other 4ohms. can it be done on a 2 channel amp?
