This weekend I will be measuring the various combos I have managed to accumulate.
Comprised of: Horns/wave guides: 2384 , PT-H95, 2352 all are 90 x 50 (Zilch very much liked the last two)
CD's 2430, 2431, 2447 and finally 2450-SL
I will do 1M sweeps with OmniMic. I'll disconnect the LF section but will use the stock JBL 4622 network
and be well clear of boundaries. Changing the x-over is not an option right now, though I'm sure Max would help me.
i just don't know how much of any subjective differences will be frequency response related vs. other driver aspects given the use of a single passive network. i'm interested in your test though...lurking for sure.
"My next upgade will be to install the Truextent phragms in the 2450 CD's."
