help with box for Powerbass 3XL 15's in Escalade EXT


Recommended Posts

I'm building an enclosure for 2 15" Powerbass 3XL's, need something that will murder some lows. Anybody have any experience with these? I have 49 wide, 23 tall, and however deep I want to go.

the specs in the manual were for a 27.5 hz tune, maybe I will just run with that one. But I was thinking maybe a sick bandpass or something like that. What program could I use to plug in the parameters?

I wrote that manual...when they changed the sub they didn't change the manual...that's why I gave you the RIGHT specs on that sub

if you want them tuned lower you can lengthen the port to 16 inches...oddly, just 2 inches lowers it to about 31Hz....below that and they sound like crap

Sweet, thanks. So, are these subs as shitty as I always thought they are? I loved the extreme subs before this generation, the ones with the chrome basket that said PBX in the middle, this generation seems like such a cheap sub.

2010 and up they cut corners to save a few pennies here and there. The amps got better, but the subs suffered. i don't like the way the speaker engineer does things...he doesn't give two shits about car audio so kinda phones things in. before the June release of 2010 product I was heavily involved with design development and production...after I left they stopped batch testing. I'll still use their amps, but not the speakers or subs anymore.

Then your the perfect guy to answer my question I posted and got no replies to in another section. How will a extreme 3000d push an SMD 18? Will it do it justice? The guy already has the 3000d, so were were gonna order a sub and give it a whirl.
