Hi...
Just started using my old pair of RB-35s again after they'd been in the closet for a few years. One sounds as I'd remembered. The other is dull...lifeless. After ruling out the tube amp's output, I swapped tweeters. And that's the problem. One bad tweeter.
The stock tweeter is stamped 3Ω K-130-DN. Poking around on the web I'm not able to locate an exact replacement. What I have found is a K137 rated at 8Ω. (Btw I've sent an inquiry to Klipsch about a replacement tweeter but have not heard back.)
Since the impedance is different, I have to presume that the K137 isn't a drop-in replacement in spite of what the web stores that sell them say. And I know very little about the math behind speaker loads. So my questions are......
- If I simply replace the 3Ω tweeter with the 8Ω unit, how does that impact the RB-35's impedance?
- If direct replacement throws the RB-35's impedance too far off the original overall 8Ω rating, would there be something that can be done elsewhere to maintain the original impedance?? Perhaps via the crossover??
- If somehow direct replacement is mathematically fine, how might the different impedance affect the sound??
Thanks all......
