I have 2 12s in a huge ported box 5.5 cubes the speakers are angled towrds each other slightly. There is little room to port the box from the front so someone suggested i port from the back of the box. Installer told me today that i should not do this due to wave cancellations and other technical stuff also said that with a box that big a port should be needed.

don't port out the back, I listened to an all ppi probe the other day, he faced his subs towards eachother and ported out the back, and it sounded like a$$! what a waste of top notch equipment. try to keep everything on the same plane for the best results.

depending on how much power you have, and the type of bass you are looking for, is what will determine what typ of cabinet to use. There are trade-offs in each case, for example; A sealed cabinet will be able to withstand high power from the amplifier, and give you very tight, and controlled bass. A ported cabinet, will provide high output levels, with less effort, but the bass may not be as well controlled, and there is greater risk of damage with higher power levels.(the port should ideally be located on the same (side)"plane" as the speakers, and half the diameter of the cone, away from the speaker and any cabinet wall.) A band-pass type, will provide even higher levels of output, with even less power, and greater risk of damage due to over powering.
There is more to this, but in a nutshell....I hope it'll do as explanation. By the way, what type of ride? how much power do you have?

Doesn't the VW Rabbit with 5 15" strokers (166dB) have its ports at the rear of each of the chambers. I thought that if you were matching the frequencies (for spl competition) then this would be desireable?
Can anyone clarify (well yes someone can but will they..)
