[QUOTE="havoc97, post: 7631972, member: 573909"] Building a new set of towers currently and have a few questions I can't seem to figure out about the impedance after the crossover. Here is the setup: ID CD1E Horns (4 ohms) Focal 6.5 Mids (4 ohms) Tang band w6-1139sg subs (4 ohms) (Odd selection of equipment, but had it laying around and figured might as well use it up) I was thinking of running a three way passive xover, and running a behringer A500 amplifier with these specs: Output power (RMS, 1 kHz @ 1% THD): Stereo mode (both channels driven): 125 watts RMS x 2 @ 8 ohms, 185 watts RMS x 2 @ 4 ohms; Bridged mono: 375 watts RMS x 1 @ 8 ohms • Output power (peak power, 1 kHz): Stereo mode (both channels driven): 175 watts x 2 @ 8 ohms, 300 watts x 2 @ 4 ohms; Bridged mono: 600 watts x 1 @ 8 ohms • Weight: 18.5 lbs. • Dimensions: 4" H x 19" W x 10.85" D. Question is, what will my final impedance that the amplifier sees once those speakers pass thru the crossover? From what I understand the amp will see 4 ohms for each frequency range, but I'm not sure if that is right.
