I need some specs for an enclosure either being sealed or ported using Four Kicker SoloBaric 10L7's running at 2-ohms on a MMATS D300HC amp. I know that the measurements of the box as if it were a rectangle cannot be any larger than 41"L x 20"D x 16"H. Can someone help me with the specs for a box? I want lots of SPL while still having a respectable amount of SQ. Thanks. Also, if anyone knows who can build me a box I would appreciate it.
