The Karlsonator is basically a DSL style double-tapped horn with a Karlson / Fulmer slot rather than a rectangular (or whatever) terminus. They usually operate over a slightly broader BW than the stock Karlson types, which are essentially modified 6th - 8th order chambered bandpass designs with said Karlson / Fulmer slots. YMMV. As a rule, the cabinets are rectilinear.
There's nothing wrong with using Perspex, assuming it's thick enough to provide decent structural rigidity. Nor is there anything wrong with smooth curves providing the horn is either designed or modified to take these into account. I'd simply advise you to be very careful about taking an existing design & smoothing the expansion path out without first checking to see what impact it may have on performance, and what you may need to do to compensate.
From what you say about the speaker's position, boundary loading should be viable, which is good in performance terms.

I think a pair of Woden Design Silbury cabinets with Mark Audio 10P speakers, done with Perspex sides might work nicely for you. You can get as creative as you want for the inside baffles which would be visible through the sides.
I have 10P speakers in Pensil enclosures in a smaller room than yours. They have very good high frequency dispersion for a speaker their size and decent bass response.

I've had pretty good luck with the Dayton Audio point source drivers. Here are 3 inch drivers with a 6 foot baffle/horn (not sure what to call them exactly they are aluminium light reflectors from an industrial building), but they are fun and get better all the time as they get broken in. The frequencies 100hz and down is covered by a subwoofer.

Nice WaveHorns!! Are those the PS95-8 drivers? I don't see the copper phase plug so looks unfamiliar. Nice driver though. Very well built and feature loaded for the money.
These are old pics with the Radio Shack Fostex FE103 clones. I replaced the drivers with the PS95-8 and never looked back. They have very few hours on them but are breaking in nicely.
