[QUOTE="Papermaker85, post: 8460498, member: 572595"] good info though.. last 18 i own was the orginal XXX with the XBL.. loved that driver.. i think i used right around 7 cubes with 80in^2 tuned to 32.. normally with a very stiff spide you can get away with A a larger box for increase efficiency or 2 larger port and decrease box size to help load the driver abit but i didn't think 6.5. the few woofers i built where built around the more linear techniques/materials possible. also taking in mid parameter shifts from not only operating temperatures but when applying it in excess as well. generally id use a slightly stiff suspension for the high mass drivers as long as i could maintain a QEs lower than .55 while keeping the FS just a bit below intended bandwidth. how you like those HDCs? i honestly didnt care for mine.. i reconed it with parts i had lying around and now shes better.. lol..
