Hello

I've always wanted to try an ESL as a horn driver:

So I employed a hi power Koss 3-layer bass module cut from Koss "model 2" spkr.

Polarizing voltage was low on Koss design so it was upped to 3kv w/ custom PS.

Horn is old closet that had a trapdoor to basement (to an old stairway - long removed).
A heavy baffle board replaces the trapdoor. Rear sound is dissipated to basement so there
is no out-of-phase cancellation (and no rear pressure loading of  diaphragms)(inf baffle).

Horn has one fold before emerging as corner loading (down to 20hz one hopes)

The sound is very deep with no apparent resonant peak like w/ dynamic drivers.
So I notice good slew-rate performance with detail and absence of the "overhang"
and "ringing" that can smear the sound w/ dynamics - especially those with taut
hi power suspensions.

Next experiment will be with a single diaphragm module (no sandwiched layers) as
I believe this can be problematic
