it might be helpful in some cases when using K-tubes on top of cabinets to experiment with a cardboard baffle at the driver's exit plane to perhaps get a better blend and support at the tube's iow end. If so, then a nice looking or transparent baffle could be made. It probably could be helpful to use felt on that baffle and also on the top of the low frequency cabinet (if one).
Inexpensive one inch compression drivers sound pretty good on K-tube the size of Transylvania Power Company's "The Tube" (1 inch diameter, ~5.3" long half ellipse based slot). No contouring of the highpass is generally needed.
Shallow K-cavities may work well with cone driver's having rising on-axis response. Look at XRK971's work with his little XKi cabinets. The .stl file shown is a tweeter lens by member Pelanj for Faital's 3FE22.
I believe apertures can be more narrow than traditional K when dealing with drivers having a lot of rise.
That K18 sounds very good imo.
When Karlson speakers are good and balanced, they can really be lots of fun and highly impressive.
I don't know who made the BLH and tube in this picture - - any clues? The slender
cabinet in the lower left is by Carl Neuser and employs a K-tube made of lamination
of maple veneer.
