DRIVE UNITS BY MANUFACTURER:
Morel TSCM 634 Midrange
The Morel TSCM 634 Midrange drive unit combines many of the Morel proprietary technologies and innovations resulting in an exceptional drive unit: The Uniflow™ Aluminium diecast chassis gives maximum undisturbed airflow and minimal rear reflection; the Coppersleeve / Faraday pole piece negates rising voice coil impedance therefore maintaining linearity; the motor system is superbly engineered featuring a Hybrid™ Neodymium / Ferrite mixed magnet assembly, a Titanium voice coil bobbin and a large 3" voice coil wound with Hexatech™ Aluminum wire.
The TSCM 634 features a composite sandwich cone composed of Carbon Fibre outer layers bonded to a Rohacell® structural foam core - a cutting edge technology more commonly found in the aerospace industry. The extremely rigid and light cone offers a highly dynamic sound with great pace and control.
The frequency response is tailored specifically for midrange reproduction and is very flat with superb linearity between 1-5 kHz. Power rating is 150w nominal and can withstand short term peaks of 1000 watts. A full datasheet can be downloaded from the bottom of this page.
Superb drive unit - highly recommended.

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
I always knew that Linn should never have stopped using Hiquphon tweeters. What I don't know is why it's taken me thirty years to fit a pair in my old Kabers. It's often hard to describe sonic character ....but to pinch Linn's old line from back in the day ...they're Simply Better.(even straight out the box with soldering iron still warm)
As my Kabers are passive,I had been a little concerned that the the 8 ohm nominal impedence of the OW1 would mess with the crossover slope. I needn't have worried....if its shifted the crossover point its much for the better.
Warm thanks also to Will and Caroline for a service in keeping with the outstanding quality of the Hiquphon product.

Been looking for a supplier of replacement drivers for some years.
Willy's HiFi had just the parts at a good price and they arrived in a couple of days.
