Bought a pair of these to replace the failing drivers in my 20 year old Alesis M1 Active Mk2s. They are physically a near perfect match for the cabinets and are a good match electrically for the amplifier, but sound better than the original drivers. The only slight complication is the original drivers use one 2.8mm and one 4.8mm spade terminal, so you need to change one of the connectors. These have given my old monitors (now my 'kitchen speakers') a whole new lease of life. Next step is to replace the rubber surrounds with a grille.
There is a detailed review of these drivers over on youtube: https://www.youtube.com/watch?v=NCb-rzCSK2s
Great service from Willys. They were dispatched straight away and arrived next day, very well packed.
Thanks for the review Malcolm !

Surprised that there was no review of these drivers so I thought I’d do one. Upgraded my 30 year old mk1 Keilidhs with the Monacors. Really easy to do if you’re handy with a soldering iron. After 50-100hrs of use they are now really settled in and on song. Same old Keilidh sound with just more of everything. After doing the tweeters a few months ago it’s feels like I’ve bought a brand new pair of Keilidhs for a fraction of the cost of modern equivalents. Well worth doing if you want to keep your Keilidhs. If you want to keep the original anti diffraction rings, the plastic rings attached to the Monacors will need to be very carefully removed. I found this easy for three of them as they were secured with rubber type adhesive which came away without pulling the rubber skirt of the cone, but the forth was secured using a stronger black type sealant which pulled at the skirt in two small places. This was easily secured and sealed so no problem just something to be aware of. The drivers look ok with the plastic rings but I thought aesthetically better with the originals.
Thankyou for your review Paul !

Up and running again exactly what I needed. Great job Willys. 10/10👊🏻🫵🏻. From start to finish will be use again in near future for crossover upgrade. 1st time using. 100% will use again
Since 1991, I've had Linn Keilidh speakers, which I upgraded a year later to an active system using the Linn Wakonda and two LK100 power amplifiers. Over the past few years, I’ve considered replacing my audio setup with a more compact active system. However, the downside is that it would require a significant investment to achieve a comparable sound quality.
In the end, I opted for an upgrade of the tweeters and new speaker covers after more than 30 years.
The upgrade itself went smoothly using the supplied solder. I’m very pleased with the end result. The upgrade has had a noticeable impact on the soundstage: the bass, midrange and treble all have more space and clarity within the stereo image. This first became apparent to me when listening to vocals—it’s as if you can perceive the space surrounding the voice. And the longer you listen, the more this spatial detail stands out.
I’ve turned the amplifier up slightly, as creating that sense of space seems to require a bit more power.
It’s an upgrade I can definitely recommend.
Wow, just had my Mission 753 upgrades of crossover and also tweeters. What a difference it’s made! The high frequencies are more refined and OMG, the separation and richness of mud and bass if awesome…..much thanks to Willy’s for giving my 753’s a new life 😀😀
Excellent advice from will as usual and exactly what I wanted. These have improved the sound of my current speakers and taken them to another level. Sounds superb I can hear tonal difference's between things that I never heard before. Superb bass drivers dig so deep.
As usual will has been outstanding.
Brilliant to deal with always helpful and gives great service.
What a brilliant capacitor, from first listen exceptional clarity and depth. Bargain will be buying more.
