lanman31337 Posted March 25, 2009 Report Share Posted March 25, 2009 They are very inefficent. You can use 2 subs in the same sealed air space as one would be, but you lose half of your power. If both subs are 300 watt rms each, you could only put 150 rms to each sub. It saves space, but with shallow mount subs and subs that like small boxes, Isobaric aren't used too often anymore.

cracker Posted March 25, 2009 Report Share Posted March 25, 2009 Isobaric is great for small box applications, but you can run only roughly half the power to the speakers. I don't know if some of you older guys remember the Advent Temple of Boom. It was 2 10 inch woofers in an isobaric pyramid enclosure. ...older guys?! lol 30 is the new 20 they say j/p i remember the temple of boom some what... i think in one of my dads old crutchfield back in the day lol or someplace like that haha Quote March 2010 SOTM winner my old buildhttp://www.stevemeadedesigns.com/board/topic/50219-dank-aka-crackers-bonne-new-v2-build-in-the-works-hahahaaaaaa/page__hl__crackers my youtube page - http://www.youtube.com/profile?user=jackiedan04#g/u my feedback - http://www.stevemeadedesigns.com/board/topic/56540-official-cracker-feedback/ i need tacos and bass to live!!!!! and will NEVER change hahaaaa TEAM NOIZE VIOLATION Link to comment Share on other sites More sharing options...

kingsuv Posted March 26, 2009 Report Share Posted March 26, 2009 I use those tubes with my 16 12's in the X Quote Designing, building, and shipping boxes. Yahoo IM - kingsuv00If the listening level is too loud, please inform the driver, so he can promptly pull over, and let you out. not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more.

lanman31337 Posted March 26, 2009 Report Share Posted March 26, 2009 Volume = PI x radius squared x height. That'll give you cubic inches. Divide that number by 1728 to get cubic feet.

Airborne Posted March 26, 2009 Report Share Posted March 26, 2009 Volume = PI x radius squared x height. That'll give you cubic inches. Divide that number by 1728 to get cubic feet. It is approximately equal to 3.14159 in the usual decimal notation Quote Link to comment Share on other sites More sharing options...
