faralint Posted July 12, 2014 Report Share Posted July 12, 2014 What about box for two dc xl 15 in trunk. I think about box like this. http://i023.radikal.ru/1407/24/d4dfbb4142fc.jpg Sealed about 1.4-1.5 per sub ported is 6 cubic aftet all diplacement. Port about 95 sq.in tuned to 45 hz Build log - http://www.stevemeadedesigns.com/board/topic/173832-audi-a6-trunk-build/page-3 Link to comment Share on other sites More sharing options...
CleanSierra Posted July 12, 2014 Report Share Posted July 12, 2014 Seems low on port to me for a bandpass. I'd feed that much port to a regular ported box, not a 4th order bandpass probably. The last 4th I designed was for some old school Fosgates with not nearly the throw and they were going to have 220" of port. It's up to you though, you can try it to see if it works. Port area seems to be a mystery to some, it was to me at one point. What brought you to the decision for the amount of port you're using in this design? Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
faralint Posted July 12, 2014 Author Report Share Posted July 12, 2014 CJ from this forum. From dc audio. Found some topic from CJ, he advised 15 sq.in per cube of ported box.

CleanSierra Posted July 12, 2014 Report Share Posted July 12, 2014 Yeah, he was referring to a straight forward vented enclosure(which is a 4th order btw), not a 4th order bandpass. Port area per square in isn't my bag. I would rather port to the subwoofer's cone area, tuning and Xmax. 4th order bandpass enclosures require more vent than a typical regular ported box. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...

Smoove Posted July 12, 2014 Report Share Posted July 12, 2014 CJ from this forum. From dc audio. Found some topic from CJ, he advised 15 sq.in per cube of ported box. 15sqin per cube is for a regular ported box (4th order) . The pic you posted a link for is a 4th order bandpass. Clean Sierra is giving you port size for the ported side of the box. 2 Team Fi 15's v1 2 DD M5's 970amps of Alt 6th order blowthroughThe truck Blowthrough build : http://www.stevemeadedesigns.com/board/topic/155555-smooves-1996-chevy-ext-cab-c1500-slow-build/The 350z build : http://www.stevemeadedesigns.com/board/topic/170694-smooves-2003-nissan-350z/ My FB page https://www.facebook.com/pages/Smooves-Car-Audio-and-performance/719746144805343 Team Fi Audio http://www.ficaraudio.com/ Link to comment Share on other sites More sharing options...
