5K Mobile Electronics Posted February 18, 2011 Report Share Posted February 18, 2011 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. Quote Check out our Youtube Channel and "Like" us on Facebook!

RAM_Designs Posted February 19, 2011 Report Share Posted February 19, 2011 I haven't messed with them, but I heard they like larger boxes. Something like 8ft^3 for a pair, from what I've heard.

Superjay Posted February 19, 2011 Report Share Posted February 19, 2011 I might have a little experience with them. you can make that 14 deep. use a 6 inch port, 14 deep to tune to 41Hz.

Superjay Posted February 19, 2011 Report Share Posted February 19, 2011 Kxm should be eighty point nine zero one Quote Principal JTech Consulting - Leader in 12-Volt Training and Product PlanningIt's not about how much power you have, but how well you use it Link to comment Share on other sites More sharing options...
5K Mobile Electronics Posted February 19, 2011 Author Report Share Posted February 19, 2011 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? Quote Check out our Youtube Channel and "Like" us on Facebook!

Superjay Posted February 19, 2011 Report Share Posted February 19, 2011 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 Quote Principal JTech Consulting - Leader in 12-Volt Training and Product PlanningIt's not about how much power you have, but how well you use it Link to comment Share on other sites More sharing options...
Superjay Posted February 19, 2011 Report Share Posted February 19, 2011 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 Quote Principal JTech Consulting - Leader in 12-Volt Training and Product PlanningIt's not about how much power you have, but how well you use it Link to comment Share on other sites More sharing options...
5K Mobile Electronics Posted February 19, 2011 Author Report Share Posted February 19, 2011 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.

Superjay Posted February 19, 2011 Report Share Posted February 19, 2011 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.

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.
