[QUOTE="NSTALN, post: 8470150, member: 588169"] The Alpine Type-S is indeed an underhung design...which is more geared towards SQ than SPL. That being said, I modeled the SWS-12D4 in .6 cubes and it's really not a good match. The SWS-12D4 wants to see a sealed box volume of about 2.6cubes to yield a QTC of .706 and Fsc around 44hz. Using a .6 cube sealed box you're looking at a QTC of about 1.013 and Fsc around 66hz....not very desirable numbers. With .6 per sub I would recommend the Sundown SD3-10. You could feed them about 400rms before reaching xmax. In a .6 cube box your QTC will be around .789 and Fsc around 48hz. The SD3-10 is also an underhung design. [/QUOTE]
