sizing 8 & 10 Karlson type -?

[freddi]

(I need a functioning table saw) Indications from original aspect 10"coupler with Beta 8CX & 10CX gave impression that 8 and 10K might be ok players with a fair amount of punch. A 10K wiht ~1 cubic foot rear chamber was a bit tight for 10cx and perhaps too much depth and baffle-tilt on the front pipe. 8CX played a bit lower with somewhat less upper bass output than 10 and both had similar (too much) output in what appeared to be coupled-cavity peak region. Beta 8cx & 10cx are tough to pop and qts pretty low. Wonder what might be the best pipe height and width vs Sd when attempting these size couplers?

one builder had about the following size for 10K - flare may have been KenL's "trax 60"
