R,
I'm not quite sure exactly what you are after, but if you remember my idea of filling a horn with a dense gas and having a gas tight, but loose mylar sheet to seal it in at the mouth... that will extend the LF, but you'll also get a greater impedance mismatch at the mouth.
I wonder if the resulting reflections may give you some of that quality... the gas to use is SF6, which would cost a fortune, but CO2 might be much cheaper and give a gentler mismatch.
Slightly higher speed of sound would also change the alignment...
Just a thought..
