[QUOTE="phyphoestilic, post: 3133475, member: 569258"] 1.5cft @ 28hz is what they recommend for a large enclosure. 1.3cft @ 30hz for a medium 1cft @ 32hz for a small. I think they know what they're doing and I would trust their recommendations. 28hz tuning will get ur allow better response for the lower frequencies (but generally doesn't get as loud as tuning higher), but at the same time since the enclosure is a little bigger in size it'll make up for the output u'd regularly get from tuning higher. I love my low frequencies, and since u want SQ (general def for sound quality is getting the flattest response in all frequencies) tuning to 28hz would be ur best best. (unless of course u want to stay sealed) The higher u tune the more output u'll get, since u have a IDQ im pretty sure u've got the flier that comes with the subwoofer. If not goto their site and check out some of the tech pages for the IDQ. They have a response graph and it show's u the different outputs between the sealed and ported. [/QUOTE]
