Crossover resistors
After a speaker cabinet went out on me I took it apart and tested each
speaker , 3inch,4inch and a 15 inch. All seemed fine. I replaced the 2 caps (1.5 and a 6) and the resistors (5w 2.2 Ohm) .These are the same values as the old ones. Almost no sound was making its way to to the 3 or 4 inch. speakers. I removed the resistors and it sounds as good as it used to. My question is what funtion does the resistor play? Does it protect the speakers from overload? Thanks |

Thanks Presumably they contribute to the crossover's frequency domain performance -- e.g. its Q. -- The e-mail address in our reply-to line is reversed in an attempt to minimize spam.

Thanks Resistors mainly control the amplitude to adjust drivers outputs. Very few drivers have the same sensitivity. The resistors also can increase power handling, have effects on crossover frequency and phase, and can change damping. Off axis response will change and response will change. Somehow your not going to get the same response by bypassing the resistors. Changibg capacitor types will also change things. greg |
