Gentle 15 degree bevel on the side panels, wrapping from back, to top, then down the front.

Starting to finish with stain conditioner.

Gotta get them done for Christmas!

Any issues with the size of that fat brace? I drilled lots of holes, so it shouldn't affect the performance much, right?

Hmm, missed this post........technically, the holey brace should be vertical in high aspect ratio cabs since the major stress is along the longest axis and to maximize airflow, so can be a solid piece, but if the deep bass response is solid, then can't be restricting enough to matter.

Re stuffing; no experience w/polyfil, I mainly used loose and/or duct board fiberglass [AKA OC703 nowadays] insulation and later, Miraflex, an itch-less roll version.

Normally I loosely covered any drivers, XO with cheesecloth for the loose stuff and for just a portion of the cab, packed it in a cheesecloth 'bag' and suspended it from the top to hang down where I wanted it.

With really big cabs I sometimes 'took a page' from Bozak, using a hanging blanket of insulation, though of course it can be done in smaller tall cabs too and recommended it a few times to apparently 'deaf ears', so quit [pg. 48]: How To Build Speaker Enclosures By Alexix Badmaieff & Don Davis : Free Download, Borrow, and Streaming : Internet Archive

It worked then. So naturally, it couldn't possibly work now.

Oddly enough, works for me.
