BassAddict32 Posted July 26, 2009 Author Report Share Posted July 26, 2009 Mount the 2 HFI12D4's isobaric in the bandpass enclosure and half the size of the sealed chamber ... It will play with 'a bit' more authority ... so like this? http://www.the12volt.com/12voltimages/isobandpass.gif Quote 1994 Ford F150 reg cab 2 HFX 12's Audiopipe APSM-1300 Link to comment Share on other sites More sharing options...

BassAddict32 Posted July 27, 2009 Author Report Share Posted July 27, 2009 Yessir you know, that's not a bad idea. have sealed and ported, all in one box. but how would i go about the wiring? like shouldn't i have it push-pull so they don't interfere with eachother?

BassAddict32 Posted July 27, 2009 Author Report Share Posted July 27, 2009 i was thinking about doing something like this for when i get 4 of the 12's. what do ya think? http://www.the12volt.com/12voltimages/isobpass3cham.gif Quote 1994 Ford F150 reg cab 2 HFX 12's Audiopipe APSM-1300 Link to comment Share on other sites More sharing options...
dred Posted July 27, 2009 Report Share Posted July 27, 2009 (edited) you know, that's not a bad idea. have sealed and ported, all in one box. but how would i go about the wiring? like shouldn't i have it push-pull so they don't interfere with eachother? Again: Yessir I've never built anything like a Bandpass 3 chamber isobaric thingy but as long as you half the size of the closed chamber (when going iso) you're fine. For instance: 1 speaker:1 cuft 2 speakers: 0.5 cuft (if you don't it will peak even lower) My gf is running a Bandpass 3 chamber in a cabrio with good results. So it's a pretty powerful design. Be sure to tune 5 hz above the frequency you want it to be, it peaks lower. Edited July 27, 2009 by dred Quote Link to comment Share on other sites More sharing options...
