the box i have right now is about 4 cubes tuned to ~25 Hz.
i didnt build it right, and im not really pleased with my SPL score. not that im really in to SPL, more of SQ, but i would like to at least break 140db.
i have a 15" Diamond Audio D9 powered by a JBL bp600.1 @ 2 ohms = 600 watts.
im going to go with a sealed box when i compete in SQ (got that in the works)
and id like a ported box for when i "try" for SPL
going to use a 6" aeroport
MAX DIMENSIONS are:
tuned to about 38 Hz
maybe around 3 cubes? idk, just make sure that it will be LOUD! (for me )
(ps... have $$$)
