Building LH 6765-13 Vacuum Box

Hi all!

First off, many thanks for all of the incredible work that's gone into the development of vacuum hold down systems on here.

I've read every vacuum hold down thread i could find...

And am now building a box for two LH 6765's that I got from Ward Lartsch.

I'm guessing that there are others in here who have also done this...

I'm going to build the box so that both motors are running in parallel, in other words, both creating suction in one section of the box, but not running through each other (in series).

I'll make baffles like in the black box design for noise, and basically just work from there.

Does anyone have a cutting file for a box of this spec already before I start designing it? If not, I'll post mine here when I'm done so others can use it as well.

A 5 zone plenum up top, and all should be a go.

This thread is basically just to document my build. Any advice is greatly appreciated, particularly in the design of the vacuum box.

Thanks all!
