Sergeant_Skyrim Posted August 13, 2013 Report Share Posted August 13, 2013 Or you could even do separate chambers for the subs with a center port that's shaped like an L into each of those chambers. What's the setup though? Vehicle, orientation, etc? Build in progress Link to comment Share on other sites More sharing options...

bkolfo4 Posted August 13, 2013 Report Share Posted August 13, 2013 X2 on combined, but I would do the port between the subs for a daily music box. Current system: 1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s Previous systems: 2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz. 1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

Tried googling and the JBL site says that they either come 2 or 8 ohm but that they're DVCs. And what's your goal? Just a daily vehicle for you to listen to?

Sergeant_Skyrim Posted August 13, 2013 Report Share Posted August 13, 2013 I vote for center port with either subs and port firing forward if you're sealing off the trunk, or both firing to the rear if you're not Build in progress Link to comment Share on other sites More sharing options...

Sergeant_Skyrim Posted August 13, 2013 Report Share Posted August 13, 2013 Sealing the trunk = making sure that all of the empty airspace in the trunk stays in the trunk. Box gets pushed all the way up the the front and then you seal off all the airspace around it with panels/foam/however you want to do it. Basically reduces the size of the cabin Build in progress Link to comment Share on other sites More sharing options...
