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 !

Used in a DIY LS3/5a project, with Morel CAT 298 tweeters and custom crossovers using ClarityCap CSAs. Super pleased with these woofers! I think they synergize well with the “live” thin-wall LS3/5a cabinets. The sound is neither bloated, nor thin, just revealing, spacious, and with very lifelike tone. I’m so happy with the results of this project and had a great buying experience with Willy’s. Thank you!!
I used this in custom LS3/5a speaker enclosures along with Monacor SPH-135AD woofers and custom crossovers using ClarityCap CSAs. The tweeters have a very pure sound, revealing microdetails and having a naturally smooth, response. The sound is never peaky or rough. I’m very happy with my purchase and with the service from Willys. Would buy from again for a future project!
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.
Absolutely first class service again brilliant advice as i always get from Will. Bought some Morel CAT 328-110 Tweeters and they sound sublime and the detail is incredible. Not harsh at all and very airy performs well beyond its price point im so glad Will advised me on this as the perfomance is fantastic. In fact Will has saved me thousands as replacing drivers has saved me investing in new speakers first class service once again.
Very happy customer thansk again.
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
