I have a pair of JBL Signature C34 cabinets with original parts – 130A, 175DLH & N1200. They are working fine and sound great except at high volume, I believe I am experiencing distortion at about an octave below the crossover point (600hz).
Just wondering, is this a characteristic of this system? Is it the woofer being taxed at it's upper limit, or the horn at it's lower limit? Is there an upgrade or replacement to this crossover? Is it possible to get this crossover to have less distortion? Does the crossover even have a distortion spec?
I have always used clean McIntosh power of various vintages. My Mac C34 (coincidence?) preamp has an equalizer, and by rolling off the 500hz band, I can minimize the problem.
Your thoughts please...
Thanks!
