I have my new Vifa drivers, foam board an plywood - just need a block of time. All the reports are very encouraging. I may have missed the post, but is the router bit you mentioned just for creating the driver mounting hole? Don't see where else it could be used.

bcmbob,

Yes, the router bit is for the driver mounting hole. I just feel like the tighter I can mount the driver the better. The Vifa is very tiny and not a lot of mounting room. I will probably use masonite or thin plywood for the front surface. You can only torque foamcore so much before it shreds or compresses. I get some buzzes at high volume on model one I attribute to poor driver mounting (and possibly inner stuffing needs).

Good luck on your build! Lots of fun.

The B20 is the 8in driver right? I asked about using the Visaton B200, also an 8in driver, and the answer was: "it will be huge"

There's no sim for it.

Thanks, I have 1/4" luan plywood (will upgrade if necessary) so should be good.

I typed the FF85WK specs into Don's Akabak script and here's the result.

In the short term why not glue some small pieces of wood behind your mounting holes for better bite.?

I actually used the rounded edge of the countertop, not the sharp edge and formed it much like what happens in a metal rolling machine. The result was a nice compression of the foam at the scores. A nice smooth bend.

This is how I did it and it works fine. The foam compresses a little is good - acts as a gasket to seal driver to face.

phew, 14 pages later....

Was looking for something to put my FR1225S's in. My old 7L towers have outworn the WAF.

Toyed with a PVC Pipe, but getting 6" PVC is not cheap or easy.

I'm surprised no one has thought to vinyl-print some artwork to go on top of the baffle. Probably one of the more decor-flexible designs for speakers I've seen.

Lucky me, I have access to a vinyl print sign making friend.

So my hand is up too.
