I'm a zero at best - but its cool to be able to sim that one style. At age 71 I need a new "Karlson" more than horns

here's a stab - might have goofed in a big way (? didn't have a printer or ruler so held graph paper up the the screen to figure stuff) - its huge

dunno if its even ballpark - could not get the spec of the supposed 12 inch speaker

Thanks David for the detailed explanation.

(Is this arrangement something Brian Steele could put out as a worksheet?)

Not sure, but I think it could be a bit tricky to do. You would need to ask Brian :-).

just putting in numbers - does this thing look "useful" ? I'm not sure how it would be built even as a rectangular box. Its pretty big.

Baffle = 18.5" by 22.5" and a mouth area like PWK's La Scala
