here's one of Carl & Wayne's klams from some years ago - I think it may have used a Polk 675 coax with a k-tube on the dome tweeter
An externally hosted image should be here but it was not working when we last tested it.
the KR5 Rocket in a way was the first klam - Karlson in 1961 had a letter to Poppe talking about an early 8 inch klam - - I'm guessing in operation the metronome shaped rocket above was rotated and mounted with a bracket to the ceiling rather than firing straight up. IIRC the cutting angles are typically six and twelve degrees for the Rocket style.
cardboard might work for prototyping. If results seem usable then a wood or perhaps a diagonally sliced pvc pipe with wood wings would make a finished speaker. It might take a homemade miter box to to get a clean slice with pvc pipe. I'd like to hear the Phase 3 klam made out of 3/4" plywood rather than the original flexy particleboard.
one thing Carl mentioned was making little driver K tall out of pvc or cardboard tubing - I think the vertically oriented pipes were around 30" tall, driver angled as with regular Ultra-Fidelity type, a 2/3 height slot. I assume there was some sort of back chamber but maybe not - ?

This is freddi's post on YT, originally from Roger Russel's archive I believe. Thanks for putting it up as it may catch a few new viewers from here, it's great to hear these audio old-timers.
