There doesn't seem to a good optimized TQWT design for the CHX-70 drivers though. All of them seem to be generalizations like the Needles and the FH Mk. III if we can count that one.

Well if you accept the definition of a Voigt pipe as a TQWT(P) design, then Woden Beltane would likely qualify. I've certainly yet to hear any of Scott's recent designs that weren't well optimized for the target drivers - indeed he generally takes exception to builders randomly trying drivers other than the intended.

I haven't built a pair of these yet, but unless there's a good reason not to, I'd be inclined to mount the driver on the slanted face ( a la Cain & Cain Abbey)
