Hey fellas, I'm gonna be building a vented box for the pioneer ts w3002d2 subs and I have some questions. Per Pioneer's manual, the best SQ ported box is 1.6cuft (gross) with a slot port of 13" H x .54" W and only 2.5" deep (converted from the round port of 3" x 2.5"). Now I know this sub is made to work is small enclosures, but these numbers really seem out of whack to me...especially the vent length. By my math, a 1.6cu box (1.42 after sub displacement) with a port surface area of 7.065sq" (the area the 3" diameter they suggest has/same as a slot port of 13"x.5") would need a 12.5" in port depth to be tuned at the subs resonant frequency of 30hz. The specs they give would have the box tuned to 52hz. Am I missing something or are they really indicating that their SQ enclosure is tuned to 52hz?? Was the 2.5" in the manual a typo that meant to read 12.5"? Any help would be much appreciated...

I'd just avoid those recommendations altogether. Unless the sub has really weird specs, you generally can't go wrong with 1.75-2.25ft^3 with a 33-35hz tuning for most 12" subs on the market.
