how do you tune a box

it all depends on the sub, the box and the surface area of the port.. we could help you better if you have those dimensions

i have an mtx and an excursion 12" subs inside an q-logic box(bandpass) and it has 6 port holes. three on each side

well, u need to know the length and dia. of the port(s). anywayz, if u want to change the frequency for the box u have u have to change the ports.

me personally i'd ditch the bandpass box and get a sealed or ported....bandpass kinda **** unless designed for a specific sub......very poor freq. response except for a limited spectrum
