Default FE206En & Karlsonette (1st K12)

at this point I give up on the idea of radiusing corners, graphs, so on and so forth - in general the little Karlson sounds better on vocals and guitars than my direct radiating midrange BK20 with 1772 and its bass conveys a drum more lifelike than the blh or my Khorns. Face it - there's poor sounding speakers which make good enough graphs and there's also adherence to TS based alignments which still result in non-dynamic speakers without good resolution of the bass-lower mid region. Sheer extension without a sense of pitch or ability to reach usable spl is useless.

the FE206En / K12 combo is a bit "warm" - no contour filters should be needed. I did notice a peak - peak excursion of about 1/8" on repeating bass drums strokes. My SM70 developed trouble on its other channel so had to switch to an AlephJ clone which seems a bit more mellow. This little Karlson combo is pretty cool - maybe better than some K15 coax setups. Unfortunately I've only one Kalrsonette. I'm not sure how FE206En (stock new model) nor 1772 play in the later distributive slit K12. The old cabinet does great with period Johnny Cash and Luther Perkins (btw-Johnny had a Karlson in one studio picture) - After the Karlson/FE206En on Cash's "Get Rhythm" I listened to the 1772/blh at the same transformer attenulator level - and it sucked in comparison on that cut. (the direct radiator had a blaring 'quality' and perhaps there's something to be said for the Karlson's asymmetric pattern(s) and its indirect reverberant components) Maybe Zobsky can poke a 1772 or 166 in his later style K12 and give an opinion. (I've one 1772 in the tiny 1955 design 8K and it has very good vocals but too much compromise on size)

one more thing, my particular Karlsonette was made of 5/8" plywood outer shell laminated with 1/8" smooth hardboard then a formica skin so the shell and wings are pretty much inert. Baffle and port panels are 1/2" plywood.

you're the only one so far to ask for special secret "Karlsonette" plans by special Karlsonite (front molding lip normally forwards on reversible port panel)
