SPH8M
I bought a pair of Acoustic Research AR28LS speakers back in 1985 for £129 ! After about 15 years the foam suspension had started to perish and completely failed in 2006 following a rather loud teenage party. I was never happy with the Eminence Beta-8A replacements bought from a local shop at the time, as the bass resonance was far too high. Finally decided to replace them with Monacor SPH-8M and the speakers now sound as good as new. Arrived quickly and no problems fitting. Many thanks.
Thanks for the review Pete. I remember selling the AR28LS when working for 'Hifi Markets' many moons ago - like the smaller AR18S but with some bass !

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 😆
thx you so much for helping me geting the twiters for my speakers i hope all good for your bisnis in the futur and that it will never close i recemed you to the norwigen hifikluben its a store in norway for parts and hifi so you brobely will get order from ther now thx agine for the parts btw you need to put a bit of fome on the back side of the speakers for it to mount in the b&w cmd1 se to make them fit i will leave som pictur of the istalsjon
