    2 designs for a Sundown SA12

    Hi guys a couple quick questions about choosing a box design. I mocked up 2 different designs and am not sure which would be a better choice. The first one is 2.1 cubic feet (after displacement) with a single 2" wide, 26.5" long, 14" high port. Its tuned to roughly 34Hz

    The second design I think looks better but Im not sure about the performance due to the narrow ports. Anyway its about 1.9 cubic feet, with 2 ports. Total combined port length is 37", they are 1" wide and 14" high. Tuning is roughly 32Hz.

    I do like the slightly lower tuning and the symmetrical design of the dual ported box. And unless I messed up on my math somewhere specs should be pretty accurate. So which box is a better design? In terms of performance? Oh yeah its going in my 03 Tiberon powered buy a Soundstream Rubicon 800.1 @ 1 ohm. Thanks a lot guys

    PS Im looking for SQ more than SPL.

    I came up with a Kerffed design I think I will end up going with. 2 cubic feet @ 34 Hz. The slot port is 2.20 inches wide, 14.5 inches high, and 33.125 inches in length. I only wish I had the knowledge to make it more symmetrical and have 2 kefferd ports, one on each side.
