Short version? ;) No. Not by itself.

No.

There are certainly general rules, but you have to stick the numbers on a modeler and figure out what works.

Bob - thanks for all you’re doing to continue the availability of these great enclosure designs.
I think you need to post your URL in signature line, or are you already in the vendors’ sub-forum?

Found it, very nice.
Bob, can you tell what are those L shape pieces of wood for?

Hi Chris,

Thanks for the heads up. I thought I did that already.

Hey Cindra,

Those are squares to help with the assembly. I figured not everyone might have appropriately sized squares on hand so I cut some out of the waste and send them along. At no extra charge of course. I may have mentioned I am making little changes in the kits as I go along to make things easier for the consumer and for me. The squares was one thing, and now I am adding marker holes on the inside of one of the "non-dado" side so that one can easily screw the "second side" on if you want to play around with the stuffing/tuning over time without having to rely on clamping the side on. This will help the WAF during the testing phase of the job. Of course, if you want to just go right to gluing the side w/o the screws for testing, no one will ever know they are there.

And thanks for the kind words!!

Bob

Very user friendly, I really like that approach

Does dado depth change some dimensions from this pdf plans? http://www.frugal-horn.com/downloads...1v0-060518.pdf
Can baffle top and sides be rounded and up to what radius without diffraction problems?

Yes, dados would have to be calculated into the cut. On our flat-paks the indife dado meant 5mm wider interior panel and 10mm wider external panel (not a god idea to have a 2nd interior dado on the other side).

No chafer or roundover is worst for diffraction, the bigger the better (limited to what you can fit), up to exotic suprabaffles that have the top of the FH looking like the mid cabinet off a B&W Nautilus or an Eclipse.
