SP-90
I purchased 6 off Manacor SP-90 Bass speakers to replace the speakers in my 30-year-old Wharfedale Valdus 500 tower speakers. The foam suspension had deteriorated into pieces. With a little bit of fettling the SP-90’s fitted and they sound even better than the original speakers. The PDF datasheet on the website was a great help in choosing these speakers. I would highly recommend Willy’s Hi-Fi as the service was first-rate.
Thanks for the review Roy !

Got two of these SP 90's to replace some 30 year old, faded and worn out, Technics bass speakers in my 3-way. What a difference, with the right amount of wadding in place, these two little monkeys pack a right punch!....

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
