to see if that restores the channel balance?

I haven't.
I did email Lockwood to see if they could advise on / offer remagnetiseing. But haven't heard back.

Also I'm wondering whether the greater roll-off of HF on the one channel could be caused by demagnetisation? Maybe all frequencies would be effected? I can only guess though. I'm not physicist.
Some rummaging around on the net has uncovered several other people with similar problems, and some suggestion that Tannoy units of a certain vintage are simply not very well matched.

It is something I'd be willing to give a go tho. Depending on cost. Do you know anywhere else reputable that offers it?

The remagnetising thing. Great Plains Audio in the states offer it. They are highly reputable.

I'd welcome suggestions from anyone else on a UK based remagnetising service.

We may be looking at someone that does this for pro speakers?
