RTR III E speaker repairs

[timmeh1994]

Nice looking speaker, they look like foam surrounds to me. Since the woofer does work, it could be the voice coil is rubbing,(does move freely, when you gently push on it with no drag compared as does the good woofer with power OFF?) or perhaps a bad connection or crossover component. I would disconnect the woofers from the cabinet wiring, and ohm them out , both, to see how they compare. If they read the same unconnected, you probably have a bad crossover component or wire connection. If they ohm out differently, the problem in in the woofer itself.

What do you mean by ohm out. sorry im a bit of an audio newbie

Glad to help! Here's a video How:

You can buy a cheap multimeter at Walmart for about $20, or borrow one.

Before you ohm out the woofers, ohm out the cabinets, disconnected from the amp, going across the red + and black - terminals of the cabinets and compare the readings. My guess is they will be different. Then disconnect the woofers as in the video, ohm and compare them too. If the woofers are different, the problem is in the woofer (voice coil) if they read the same, the problem lies in the wiring or crossover leading to the woofer. Good luck! Let me know how you make out.
