I'm not a big fan of isobarik because it's an expensive way to throw away efficiency to get a smaller box.

I aim to drive the Beymas with a Crown K2. Was thinkin rather than dragging 2 subs, i could maybe build an isobaric. Have you built any?alex bozashttps://www.blogger.com/profile/09971033539396681678noreply@blogger.comtag:blogger.com,1999:blog-8689487740107692135.post-66850523501352689682012-08-18T16:24:34.014-07:002012-08-18T16:24:34.014-07:00Alex, I wouldn't even try.

Beyond reasons like choice of amplification, damping factor, issues of bafflestep and matching sensitivity, you also have a need to be able to make adjustments until you get the bass balance just right. Some of that has to be done by ear, but the passive method is inherently inflexible and fixed.

DO you think its a realistic aim? alex bozashttps://www.blogger.com/profile/09971033539396681678noreply@blogger.com
