Polk audio 10A crossover problem

argonrepublic · 8th May 2005, 05:14 AM

Checked everything the novice way. Swapped drivers etc. HF cicuit is weak. resistors are ok, ground is OK. There is a strange looking device in series/ parralel to tweeter. It looks like a big inline capacitor but it is marked: TI
E-0012-1
12j 100V
What is it?

Do you have a picture of the circuit? HF drivers are normally more fragle than passive componenets. If it's in series with the driver, then it could be a capacitor.

Could be some kind of protection device. If there is a regular network for the tweeter, try disconnecting the unknown device.
