I have an old Fisher speaker system. Remove the grill and it shows a
woofer, midrange, and a tweeter. Red/black connectors in back. Works well
with a Radio Shack amp.
On the back is a sticker with information about this unit:
1. Does the impedance of a speaker affect the sound quality/loudness? So
for a given power, you need a certain "ideal" impedance (resistance). And
if you use a speaker with a higher impedance, the power output will
decrease (P = V2/R)?
2. Are the crossover frequencies the lower limits of the midrange and
tweeter, respectively?
