Tannoy Gold 12" - HF not working

ringo_the_hifi · 08:54 AM

Hello.

I've recently bought some Tannoy Gold 12" drivers with new crossovers.

Thing is, one of the drivers sounds nice and the other is missing the 'tisk' or the higher freqencies.

I've taken a look at the tweeter and the dome and the surround of the dome looks distorted and creased.

Could this be the reason why I'm not getting the same sound as the other speaker?

Thanks

I dont have those drivers but it looks like the HF dome is burned

Repairable.
A few companies specialise in replacing treble domes.

If you are very competent, you can replace the treble dome yourself. Google to see the procedure.

I see... Ok, so I take it that this would seem to be the problem, or could it be something else?

The bass driver seems to be working fine.

Agreed, totally repairable, and absolutely worth doing!

Lockwood Audio sell genuine replacement parts. Also take a look at Hans Hilberink's Tannoy site - all the information you need.

ooh.. I hope it's not been demagnetised... Just been reading up on this. But surely this wouldn't kill off the sonics of HF coil when the bass driver is working ok?

btw.. I'm a newby to these.

Monitor Golds use one magnet for both bass an treble so it cannot be demagnetized if the woofer part is still working fine.
Just do not drop them! While AlNiCo is pretty much immune to demagnetization from overheating, more so than any other magnet material, they are very susceptible to being knocked.

As gyro said Lockwood Audio is THE place to go to. Roger can even fix them while you wait. Ring him and have chat with him and he'll sort you out, they've been involved with Tannoys for 50 years and know more about vintage drivers than Tannoy themselves IME.

As for being a newby, you should hopefully be the start of a very long and satisfying relationship, and fixing a few initial problems is as good a way as any to get acquainted with them. I can't think of anything I'd want to swap mine for.

thanks guys...

I think I've found part of the problem.. The tweeter is working but there are more gaskets on the good sounding speaker than the bad one. Apparently this can alter the sound to quite some degree.

I also checked the good speakers tweeter and it's mint... I think the damaged tweeter isn't doing it's job properly. The outer suspension of which any speaker needs is distorted hence not producing the volume of the HF.

Would this make sense to you guys?
