Hi!
This is my first post here and I'm hoping to find some help regarding a suitable X-over for my JBL 2445J mounted on a short (13 cm) exponential horn.
Right now I'm experiencing some "coloration" from the horns as my x-over is 551 Hz. I have tried another x-over at 7000 Hz without any coloration what so ever. But I would like to be able to go as low as possible, but without the coloration of course.
I have noticed that the x-over on some large JBL monitors is set at 1.1 KHz, so I wonder if that x-over frequency is high enough to avoid coloration, or do I have to go even higher?
Otherwise my filter is a 12 dB/oct L/R, HP: 10uF (polypropylene) and 8 mH, L-Pad (-10 dB attenuation) 7,5 Ohm/11 Ohm with a 4,7 uF parallell over the 11 Ohm.
