Crossover Issue

[derek92994]

Gents. I have these Coral speakers and one of the crossovers is not outputting to the woofer.
Have measured the caps and taken pics. Tried to trace the circuit but my limited knowledge makes this difficult. Could someone please have a look and tell me what the fix could be?
Mids and Tweets Work fine
I have tested the woofer on its own.
Where the two wires are soldered to the underside of the board, this is the woofer output. I replaced the wires.

Check the continuity of the woofer itself, both inductor coils and replace the capacitors - they are past their useful life. Sometimes they can test OK, but with variable frequencies, they breakdown.

That goofy rotary switch is suspect too

Oh, it definitely needs a good scrubbing with DeoxIT and an old toothbrush.

Thanks Gents.
I shall get to work on it today.

Can't tell just yet if they are in the woofer circuit, but also might be one of the wirewounds opened internally. Lift a leg, measure..

How distracting is the noise from those 4 fans when they are spinning

Super cool speakers, they have been lifting skirts into the air for years

Putting this on hold for a couple of days.

Need to build a pc to record music for a friend’s 12 year old son. He’s going to be ecstatic.
Priorities Gents!
