Width is typically a couple in wider than driver bezel. The aperture should be big enough to let the sound out without a cupped sound. I worry more about natural sound than cone control for a full range driver.
My W5-2143 XKi’s have been in use as HT bookshelf speakers for past couple of months. They literally are stuck inside the cubby hole made by a shelf. The family has been using them daily and powered by Dayton APA150 FRD from TV’s Toslink to an optical to RCA converter. They play quite loud with good bass extension. My wife likes them.

That makes sense on avoiding the "cupped"/"canned" sound.. 12250TC is probably better than average for K type applications.
A question - if one is contemplating an XKi alignment using hornresp, which curve might they pick below between those two front chambers? - or is the approximation too lax to determine a "winner" ?
Does the cavity peak reach full intensity in practice? Depending upon tuning and driver parameters, a "K10" size scaled Karlson can peak around 210Hz, giving a sharp emphasis to percussion.
If -3dB @60Hz at 95dB are really attainable, then this should be punchy.

hello X - when you get the time, I'd like an XKi alignment for PA310 which can hit hard at 55Hz. (-want classic drum tuning to be strong at high levels.)
Def_Driver "PA310-8" | DAYTON 96.1dB 450 watts Xmax 5mm
Sd=530.9cm2
Fs=39Hz
Mms=72.8g
Qms=8.85
Qes=0.30
Re=5.5ohm
BL=18.0Tm
Vas=91.8L
I came up with a small one (38 liter) in hornresp but not sure how it might fare. Maybe there's
a somewhat better solution.

Here's a fairly small XKi for W8-1772 - does it look feasible?
also, besides the Fane XKi, one for PRV 10FR300 might be cool.
Can you think of a way to mitigate the cavity peaks other than adding
a stub adjacent to the vent (like over top of the XKi vent) or applying EQ?
Kappa 12 looks pretty promising plus a known good Karlson speaker. That
back chamber could be reduced to one cubic foot and tune it ~60Hz.

XKi - X's ab initio Karlson 6th Order Bandpass
We use the XKi W5-2143 everyday as our main speakers for the flat screen TV used for the basement dance studio. They fit right inside the TV shelf and sound great. Very nice bass and great wide sweet spot.

Hey XRK971 - couple of questions on this proposed "stubby-K" box. (I realize a smart guy said the fudge sims are wishful thinking)
What might you change aperture wise and other-wise? Does it look basically "OK"? The smoothing stub comprises part of the front chamber and should be useful with lower Qts drivers - whether good with moderate Q = to be found out.
With my old P-Audio SN10 and 12mm plywood, it might make a semi-portable mono boombox, An XKi probably would be better for stand alone as the "FM2" box is meant to have subwoofer support.
Beta8cx XKi would be perfect in size for a mono boom-box. Have you re-thought that design?
Aperture's top moved down to just below the port's lower boundary

Do You have a drawing? It's a bit different from your post #723. I have the W5-2143's and eager to get started.
