cool tube - nice looking driver - - K-couplers R krazy and on my 42" tall k18 blocking the narrow upper slit kills some of its speed.

HF lobe in a klam or K-tube go pretty much straight down the tube

here's Karlson's idea of dispersion of KR5 rocket when mounted with base to wall to for the "asymmetric projector" - - Karlson in Acoustic Transduces 1 & 2 showed "protuberances" in some klams and k-microphones

snippet of Karlson's 1961 letter to Poppe



heres rough dims of Poppe's vertical rocket for 6"x9" - I think he kept the nose open on the MIT test K-coupler and others figuring the wave hadn't fully reached room Z - - (John Karlson didn't have the nose gap in his klams)



for something shorter as a 10" driver toy to try, here's a klam 10 by Carl -= IIRC its rear chamber was optimized for old Eminence B102





approximate dimensions

k's work well in ~K15 size
