Your subs. Meaning, on the face of the box how close can the mouth be to the subs?

Given tht those tube boxes used for SPL have the ports surrounding the subs I would say right next to each other.

the closer you can get the port to the sub, the better the acoustic coupling will be.

Thanks guys. I'm in the process of building a 5 cu ft enclosure, and don't have much room. So that helps.

Thanks guys, never asked that Q, but you reinforced what I thought or should I say hoped.

Small space as well.

Actually, convention says you should be half the diameter of the woofer away from the edge of the frame, but I have never noticed this making any big difference
