Hi,
I bought my RF-25s about 6 years ago or so and they have performed wonderfully. I recently noticed that the sound from my left speaker just wasn't matching the output of the right. Upon closer inspection, I discovered the left tweeter was not putting out the same level of signal as the left. I put in a mono CD (beatles) so the channels should match exactly, and sure enough the left tweeter was not matching the right. What's strange is that in most of the reading I've done, the tweeter either works or it doesn't.
So, first thing I did was switch the connections on my receiver (yamaha RX-V995). This receiver has connections for two sets of speakers (A and , so I switched them to B from A, just to make sure it wasn't a bad jack. Nothing changed. I took the banana cables off and reconnected the wires using bare cable, thinking maybe the banana plugs were causing the issue. I've had this happen before when the wire came loose from the banana plug. Well, using bare wire didn't fix it. So, finally I took the right cables and sent them to the left speaker and vice versa. Still the same left tweeter issue. So, I've narrowed it down to the tweeter/cross-over.
I took the front plate off and check the wires leading to the tweeter; they're fine. I then looked the cross-over and it looks fine. I've exhausted my limited ability to diagnose this issue. The one thing I was going to try was unhooking the tweeter from the wires and switching them, and that would narrow it down to the either the tweeter or the cross-over. I tried to pull the metal clips from the tweeter connectors, but they just wouldn't budge. I was afraid of breaking something, so I stopped and that's where I am now. Should these clips just pull off the connectors, or do I have to loosen them in some way?
If I can test the tweeter by switching it and it turns out it is the tweeter, how do I go about getting a new one? Also, how much do they cost?
Thanks for any help that can be provided.
