Last month somebody posted a query on OB woofer mounting.
I've been itching to make another set of largish OB speakers for while utilising some old school Road Thunder 15" i have combined with the Jaycar 12" that are really only suitable for OB use [ Qts of 1.7] and I'm intrigued by the way they described the woofer mounting.
As per my attached sketch.
Blue driver being the Road Thunder and Red being the cheap Jaycars of which I now have an even half dozen but was going to use a quad but could use three per panel depending on what mids are used
My query is this. Is there a "Best Fit" set of angles for this way of adding in my big woofer?
I'd already contemplated a second box sitting beside the tall panel but this might work best for me.
I've already decided on angled wings and a 600mm wide baffle to suit the panels I have and I thought 300mm wings would work reasonably at 45degrees

FWIW, etc., not knowing any better I just tilted it till the VC coils lined up close enough to be 'close enough' in time/phase alignment when the polarity was switched for a simple 'textbook' 1st order XO.
FWIW, etc., I didn't much care about the angle since it's OB, so baffle width was the way to tune or if wanting a wider one than needed, just scallop out the woofer's area to 'taste'. 😉
Looks like it is approaching a SLOB design: https://www.diyaudio.com/community/threads/pass-slob-build-discussion.300952/
