DRIVE UNITS BY MANUFACTURER:
D3004/604005

Based on the Illuminator D3004/602000, this 30mm Beryllium (99% Be) dome tweeter is specially selected and upgraded for optimal in car use. Features include a high power SD-2 Symmetrical Drive Neodymium magnet system, a protective multi-hex grille and a low profile tuned aluminium rear chamber making it ideal for car doors or other confined mounting positions. Built from premium quality component parts, this state of the art tweeter is rated at 100w maximum power and is fully comparable to the renowned full size Illuminator and Revelator tweeters.
All of the Automotive range of tweeters feature Neodymium magnet assemblies, these are far more powerful than their traditional ferrite counterparts allowing for a range of compact drive units that offer a level of performance belying their size.

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.
