I like the 24L 10in wide format too. My main RS225/10F speaker is 24L and looks nice.

Yes. The math works out that way - for 20% front chamber, depth needs to be 40% of total so 10in x 0.4 = 4in.

so the finished build will be about 12" deep x 11.5" wide by 16.5" tall - 5/8" BB or 3/4" "Araco" plywood. 1/2" BB might suffice with a few braces. It would be nice to make the wings rather "dead" from some laminate.

I've only one FE206EN so an XKi might be the 34 liter version for SN10C. The 60 liter XKi for 1772/Beta10cx is a bit big for my little bedroom.

I think 1/2in BB would be nice to keep the bulk down.

the FE206 XKi is just a bit larger than Beta8cx XKi Click the image to open in full size.

Beta8cx in the XKi should sound pretty good on female vocals when things are right

would FE206EN XKi's aperture look as "constricted" as with the image above?

That plan for the Beta 8Cx looks almost about the same as for the FE206E. Vent is also 0.75 deep but 10.0in long. Cabinet on FE206E is an inch taller and depth an in deeper, with a 4in deep setback on the front chamber.

with some foam blocks in the rear chamber, the Fostex version could also accommodate Beta8cx (?) - - (maybe others ?)

out of all of your K models - which one might you most easily add a stub feature to the front chamber? - Could that be useful to quell the peak seen right before the "W" fill area in K15 type? Is it useful on the XKi where the sim shows substantial rise to a peak ? (typically 200-300Hz)
