DRIVE UNITS BY MANUFACTURER:
D2905/970000
Categories: 0.75 - 2" (19-50mm) Dome Tweeters Scanspeak Tweeters

The Scanspeak D2905/970000 has a high power handling of 225W and a frequency response to above 30KHz. Features include a hand coated 25mm soft textile dome, an airflow optimised copper capped pole piece and a tuned rear chamber with an integral resonance damping plug.
This tweeter also benefits from the Scanspeak SD2 'Symmetrical Drive' system incorporating a copper capped and sleeved centre pole piece; this effectively forms a very low impedance shorted turn (called a Faraday ring) within the magnet circuit, the net result being that the voice coil impedance remains largely constant across it's operating frequency range resulting in a more linear output with greater top end extension.
This is a highly advanced design with a sweet, detailed sound. Found in many high-end designs and is a top choice for DIY high performance loudspeakers.

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
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.
