We put another BM mkIII in the bandpass enclosure in the Jeep and pulled a 144 out of it last night. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

We broke 148 with two last night... will post pictures later whenever I go back to the shop.

Will keep working on the 150.

That's cool, its fun to see what you can get out of subs that aren't supposed to get loud. Cherokees are great SPL rigs too...

First we made a REALLY small ported box... but the tuning was too high and extended the port messed up the phase relationship...

Not much better than the single woofer at it's best so we quit on this box.

So... we modified one of my dual 8" woofer boxes to hold two 12s -- about 75% larger than the first :

I forgot to take pictures yesterday... the port did have a flare on the end. MUCH shorter port.

This is what we got :
