I recently bought some RT f/x speakers that ended up having more problems than the seller indicated: one destroyed woofer and two tweeters (one on each speaker) that were not making any sound. I replaced the 5 1/4" woofers by boring the holes a bit and installing spares I had from some old R15s, so that problem is solved. I then removed all the tweeters to test each on separately and found them all the be perfectly operational, leading me to believe the issue is in the switch on the back of the speaker. The action for both switches is very loose and does not give positive bipole or dipole settings on either. It's the connection that goes to the "weak side" tweeter (the side without the woofer) that's giving no signal.
What's the best way to attack this? Is there a switch replacement I can get or is this a common issue with older f/x speakers that has a simple fix I'm not seeing? Any help would be greatly appreciated, since I obviously bought these expressly for their dual tweeter configuration. Thanks!
