  • Confirm a Faulty Tweeter?

    I recently had a friend of mine ask if I could take a look at an old B&W center speaker for repairs. Voice coils for both woofers are open and a couple of the crossover caps have issues. The tweeter was still working, but the impedance measurement makes me think it has problems too. Does this measurement look bad?

    Probably fine. Does it have a waveguide, or was your hand in front of it perhaps when you measured? That would explain the double peak. In any case, the voicecoil isn't open, so play some music through it and enjoy.
    Don't waste your money on a new set of speakers, you get more mileage from a cheap pair of sneakers. Next phase, new wave, dance craze, anyways it's still rock and roll to me!

      Not necessarily. That can be indicative of a damped rear chamber.

        More like an underdamped rear chamber.

          Thanks for the input. It does have a small waveguide. Probably just replace woofers and a couple capacitors and call it good then.

              Yea, prob'ly OK. I'd call Fs more like 1.7kHz though.
