....still a work in progress, but I thought you might be interested in my homebuilt isobaric coupled cavity subwoofer.
It should be quite something when it is finished - at least it had better be given the amount of time I seem to be spending on it!

Let me know what you think, I'm still far from finished..

Hello again!
Thanks to everyone for the encouragement!!......
Well I finished it some time ago, thought you might be interested to see the finished product.
It's a 6th order, series tuned isobaric sub, using a pair of eminence Beta 10s on a shared baffle. The enit is made from 18mm mdf, but laminated to form 36mm panels. It's a bit of a brute!

I power it from a homemade maplin MOSFET 150w amp that I built about 20years ago... The j50 and k135 fets are still going strong!
Enjoy!

I've been very interested in isobarics for many years. I've found little or no benefit from making small enclosures tiny, in which case the two drivers are not driven to the same excursion limit (one reaches its limit first). But for making grossly huge boxes tolerably large it's amazing.
I'm currently making some commercial-looking isobaric subs with 4 12's in each, in trapezoid cabinet kits from parts express (with lots of additional bracing).
It's interesting to note that with your 6th order bandpass it saves box volume on BOTH sides of the drivers!! That's doubly impressive.
