DRIVE UNITS BY MANUFACTURER:
18W / 8531G00
UK STOCK ITEM
The Revelator 18W series of drivers continue the enviable trend set by the smaller 15W versions. There's a few variants and different impedances - they are all excellent. This version is available in 4 and 8 Ohms. A full datasheet is available for download at the bottom of this page.
Popular among high end & esoteric designers - and with very good reason.
Featuring a unique cone that is precision sliced then re-bonded with damping glue; this procedure gives a very high level of internal damping and control that is not normally obtainable with a standard type cone.
These no compromise drive units offer superlative sound quality with outstanding midrange resolution and solid bass extension.

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
