These Morel tweeters would have been superb replacements for the, less than special, tweeters in my Monitor Audio RS6 speakers.
Unfortunately, the RS6 tweeters are 6 ohms and the Morels are 8 ohms which makes them incompatible and, therefore, unsuitable.
Thanks for the review Mark !

I tried this uprated capacitor through sheer curiosity and am pleasantly surprised with the results. So far, and not too many hours in, it’s giving a slightly smoother edge to the top end and has solved an issue I had regarding some hardness to the sound. I’m impressed enough that I’ll look to replace the mid range caps in the future.
New Foam covers supplies by WHF have completely changed the appearance- they look brand new! Great quality foam, very reasonably priced and quick delivery. Delighted with they now look and sound - will hang on to them forever now.
Excellent upgrade, works perfectly with the speakers it's just soldier and play, they takeaway the over intensity of the original tweeters.
I've had my Mission 734s for about 30 years and for the last five or so the bass units have been falling to pieces. I was about to take the speakers to the tip, but didn't have the heart knowing how capable these used to be. I did a little internet research and these Monacor replacements appeared to do the job. Next day delivery from Willys was impressive, as was the killer sound once the replacements were fitted (which was a simple job). I'd forgotten how these speakers make the windows rattle. Very happy customer!
Excellent service from Willys-Hifi. Caroline was very helpful and patient when answering my queries. Please be aware that some soldering is required when connecting the tweeters. Something I haven't done since I was at school over 40 years ago! They do sound good though, listening to Smoke on the Water as I write , wow 😆
