Here's my latest prototype system in the works!
JBL 2225H 15" in 3 cu ft tuned to 35hz(WT2 results), ports on rear.
JBL 2440 2" compression driver (w/2441 phase plug and Radian diaphrams) on 350hz tractix wood Edgarhorn.
Pyramid TW-47 2" bullet tweeter
Crossover: Low pass @ 500hz 1st order, 500hz high pass on Edgarhorn @ 3rd order w/L-pad, 1st order high pass @ 40khz on bullet tweeter to match attenuation to LF/MF sections. Oil caps with .01 mfd bypass caps used throughout.
Future mods to include changing LF section to JBL 2240H 18" in 4 cu ft cab tuned to 40hz, and converting to 1st order on all 3 drivers.
Imaging is excellent with only downfall is being only 7' away from these horns is a bit close. I will extend the speakers closer in the corners to gain some distance between the speakers and the listening location.
Amp is rebuilt/modded NorH SE-9 SE class "A" EL34 @ 7 wpc!
I used the Pyramid tweeter as I don't need much HF response and they cost less than more refined horn tweeters I have used in the past.
Just thought I would share in case anyone cares!
