tuned to 15.35 Hz
6" round port x 29.17" long
is what i'm showing. but there really isn't much difference is there. i'm really tempted to use this subwoofer instead of going the SVS route. Cost would be similar to the 10" nsd with hopefully the performance of the 12" nsd or greater. Not sure which amp to go with though I know I wouldn't want to be spending more than 300$ on it. Another problem is Sonotube. The local UBC doesn't carry anything bigger than 16" and while hes got good prices on it, I don't know if he can get the bigger stuff nor whether he can order just one if thats all I want.
