Fons, are you perchance old enough to remember the "Karlson" speaker
cabinet designs from back in the late 50's?
This was an attempt to take the Electrovoice corner horn and fold it all up
into a more normal looking box that actually took nearly 2 sheets of 3/4"
plywood to build. As a late teenager I built the 12" sized version of it,
and while I can't say it didn't "color" the sound, the thing I can recall
was that it was extremely efficient with a University 6201 12" coax speaker
in it. 5 watts could loosen the putty in the rooms windows. The 12" sized
version also seemed to have an LF cutoff in the 45hz range but that was
probably the speakers blame as it cone wasn't exactly softly suspended.
If any of those survive today, what do the experts think of them now,
nearly 60 years later?
