ALPINE408 Posted June 28, 2008 Report Posted June 28, 2008 I dunno about the type r but most 12's like 1 cube to 1.25 cubes sealed Quote Have you ever had your woofers blown?

EricM9104 Posted June 28, 2008 Report Posted June 28, 2008 i thought type r's were built to be ported You sir are wrong. IH8PunkRok, From Alpine's site, they reccomend 0.85ft^3 per sub for optimum sealed enclosure for a 12" Type-R. http://support.alpine-usa.com/products/doc...M_SWR-1242D.PDF Quote 2015 Honda Civic LX 4dr | 110k miles | Stock 1996 GMC Yukon SLT 4dr 4wd | 260k miles | JVC Head-unit

All Night Long Posted June 28, 2008 Report Posted June 28, 2008 I've got one R in the woman's car with 600 or so watts to it and it pounds. If you want the box specs just let me know. The box is ported though, but that would be the way to go any way. The internal airspace is 1.7 cuft and won't be much bigger than a sealed box if size is an issue. Quote
IH8PunkRok Posted June 28, 2008 Author Report Posted June 28, 2008 thanx for the help guys.
