I have a Q-logic bandpass box that has 2 ports on each side for 2-10" subs and 2 Fosgate P-1s SVC 400w @ 4 ohms. When installed they angle toward each other and are sealed by a plexiglass window. The questions I need answers to are, is this the right box for these subs, will this config. damage my speakers, and what is better for these subs ported or sealed?
