Help with my Tannoys

[anubisgrau]

do you have a señor with a simple meter nearby to quickly see where does the signal stop

Tom can you clear your inbox.

done

I Did mention in an earlier post that it could be a component in the signal path gone open circuit, although I presumed there was a resistor in that part of the circuit to cut the high frequency output.
Either way, Hope you get it sorted.
Its a shame its been so difficult to speak with someone at Tannoy, not sure what's going on there these days.
A...

Paul at RFC says it's a cap that's most likely gone open circuit though I still don't understand a) the buzzing b) why the cap that was in circuit at the time is okay.

Solution would be to send the driver and control panel to Tannoy - 10 year warranty but I'm not the original owner. I have another number for Tannoy and will try that.

Another would be to get Paul to make me a pair of his great crossovers - but if the driver does have a fault then no point in that. Never had a problem with speakers before!

I doubt it's a driver issue. The obvious thing, to me at least, would be to swap components from one speaker to the other. If the problem moves to the other speaker after moving say the crossover. Then you know where to look. I'd still start with a meter though and go all the way through checking continuity and components. It could be something as simple as a dodgy connection on the input terminals.

Thanks for the suggestion. But I'm not sure what swapping control panels will show. The driver works fine on its +2 roll off setting just not on the rest - I would imagine this has nothing to do with the driver so swapping shouldn't have an effect except transfer the problem.

I've never heard a tweeter voice coil rubbing so can't say that's what I heard - but buzzing is a very good description of it - not like a woofer rubbing which I've heard before.

Its Christmas so I'll have some time and will take out the control and post pics - bloody messy in my opinion.

[farflungstar]

Good news. The driver is fine. The energy levels also work fine - just the roll off. So.... Get Tannoy to fix or go with Paul's....

[cooky]

The crossover is hard wired, I'd reflow all the soldered joints on that part of the circuit-5 minute job. If that doesn't fix it then could well be a component gone kaput.

I'll pull the control board out and post a pic - it is so cramped, messy, and the actual connectors for adjustment are encased. Cant imagine tinkering will be easy.

Tannoy customer care (Music Tribe) have asked me to test the speaker with test tones - hmmmm what is the point of that? It's broke end of story. However they have said I can send it to Kidderminster, not Coatbridge where they are made but a (from what I can gather) general technical service used by Music Tribe, the parent company. Or a technician they 'think' can fix it in Andorra!

So, you win the lottery, buy into the advertising hype about old fashioned build and service and buy a pair of £65k speakers - which end up on Joe Blogs work bench if they go wrong.

I'm damned sure if I could just speak to one of the engineers at Coatbridge he'd be able to explain what happened and why.

The pic below is for the Kensington GR, mine are the SE but I'm sure they will be similar.

Looking at the roll off section I just don't get how the +2 can be working but all others including flat are dead.
