I was working with some 1989 vintage JBL speakers last night, trying to figure out why there was no low end in them. Got most of the full range back by bypassing the passive crossover on the woofer, but I have concerns about the amp loading now.
The highs are JBL 2245 drivers on horns and the woofers 4507 cabinets. The horns have a 16 ohm impedance, and the woofer impedance is unknown. The amps are Ashly FET2000s (L/R) and an FTX2002 (C). Assuming a properly configured active crossover before the amps, can I get away with a 16 ohm load? The amps are rated for 300W into 8 ohms.
