Need speakers that can rock with just one watt? You found da place.

The Karlson technique has failed

imo

(1)- to be dynamically outplayed on big drum by reflex or horns its bulk out of anything I own/owned. 1/8" peak to peak excursion can be very powerful.
(2) -to be beaten dynamically by reflex moving > 2X its exzcurion and putting out less power while basically flapping in the wind
(3) -to capture anyone's interest other than a secret few -- they can be problemactic but some coupler should work out nice overall.

there should be variations on K15 which work well if practical contraints and "tunings" can be determined. If a baffle is pulled forwards to a more shallow angle than K15, then the front coupler will get taller for a fixed bulk. I'm not sure how this affects the imnpedance curve.

42"x22.2"x16" coupler with 18" and 23 degree baffle

also, Zintz's K-tube of 25+ years ago was very good
