Hello,
I have a Tannoy LSU HF 15 (Reds) from around 1962. The speakers are all original, which is a good thing. The speakers do sound a bit shrill in the high tones, though.
I think the crossovers (capacitors) are no longer OK due to their age. I don't want to change the original crossovers.
Does it make sense to try out the crossovers for the 15 HPDs? I still have them here.
The Reds are specified as 15 ohms. The HPD crossover for 8 ohms. Does that even make sense??
If anyone has good homemade crossovers or used ones for the Reds, I might be interested.
Best wishes, Klaus

I have a set of Tannoy Monitor Gold’s from the 70’s and the capacitors also need to be replaced. However I’m not certain how that would affect their resale value. You should post your question on this Tannoy Forum.
I’m currently using DSP to correct any major response issues.
Good luck!

The crossover points will be out by an octave if you use the HPD crossover.
I have restored quite a few vintage Tannoys and the original capacitors had drifted quite severely off value.And unevenly so one pair sounded quite different to the other.Typically they had a hole in the frequency response around the crossover point.One pair of Golds was rolling the woofer off at about 600 hz instead of 1500hz so quite obvious.
The Clarity Caps CSA [purple ones] seem to work really well in Tannoys but you need to remove the crossover box top/sides to fit them in.

Hello,
to "DonM":
The problem is, as soon as you change something on the old Tannoys, collectors pay less!
Tannoys should always be completely original. I don't judge whether that makes sense or not!
If I understand jtgofish correctly, I can use the HPD crossover. But that's not ideal!?
I also have an old Tannoy Gold crossover here. The one in the plastic housing. It has already been changed (not by me).
There are other capacitors in it. Would that be a better choice for the Reds?
I'm using a translation program. I hope you can understand the content!?
Regards Klaus

The Gold crossover is wrong for the Reds.
If you do not want to change the original Red crossover I suggest leaving it as it is and bypass wiring in a completely new one.Mastrad in England make new ones.

Klaus,
In response to your question. I agree with the comments and recommendation from jtgofish. Trying to use a crossover designed for another Tannoy driver is not advisable. You could purchase a replacement crossover from Mainly Tannoy. This would permit you to retain an original crossover for resale in the future and still enjoy those vintage Tannoy drivers with a new matching crossover. Alternatively you could sell the speakers now and replace them with a newer alternative.

Tannoy HF Diaphragm are known to lose their concentricity over time , I had that issue on my HPD's 15 , you should check that first , especially if you have paper spacers
a good distortion measurement will tell you what
on my HPD's 15 I tried 3 different spacers , paper , hard rubber , and aluminum , hard rubber won the contest , distortion and sound wise 😉
