HR6040 must be a pretty smooth horn the way the final section flares. The P-Audio adapter is good enough for midrange and probably treble. I could compare it to a Gollehon horn about the size of 511, 511 and a Renkus-Heinz like Mark Hardy uses.
I want a passive xover for this toy - not sure what horns "here" for a tweeter - I have a little Gollehon radial but its sidewalls are ~100 degrees- could try a K700 (that would make Tom Brennan happy) - maybe there's a cheap non-CD horn at Partsexpress
(maybe there's some copper coil diaphragms at Ebay - I have K55V but both are blown after a cat did something to cause an amplifier meltdown)
here's the little midbass with a 12" - just about 7 cubic foot external bulk - where would you nominally crossover from this midbass to the midhorn?
if I could shuffle stuff, it would be fun to use HR6040 with Sentry IV
SAHF on 511B sure goes pretty low - 24uF is probably large as SAHF IIRC is nominally a 16 ohm driver
