Hullo. probably a basic question for those here, but question is.
I have a pair of Tannoy M4 speakers. I accidentally drove a pretty weird audio signal through my amp last night, not loud enough to distort. However, now the speakers sound dull, muted, muffled. The speakers all still work individually ( I removed them) Is it possible to have damaged the crossovers only? There are also no fuses or anythig visibly broken on the croosover. Thanks in advance.

Do you can remove the woofer and check it and the crossover?

Hi Thanks for the reply. i removed all speakers (3) and they all work when attached directly to the speaker wires from the amp. If I was to check the crossover, how would I do that with a multimeter, and what normally blows? Thanks.

Unfortunately to test resistors with multimeters needs remove the resistor from the circuit.

Set the multimeter to the resistance setting then connect the probes to each end of the resistor. The multimeter will display the resistance value.

Compare the measured value with the resistor color code chart.
If the measured value is within the acceptable tolerance the resistor is likely good.
If the reading is near zero the resistor may be shorted.
If the reading is infinite the resistor is open, damaged.

Inductors are hard to be brokem.
Capacitors will die in some years.
