    Great results on a tired pair of Keilidhs

    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 !
