NEW PRODUCT - IN UK STOCK NOW
The GRS PRT-8 is a modern reproduction of the classic CTS paper cone phenolic ring tweeter as found in countless historic loudspeakers from the 1960s through to the early 1980s. With a smooth broadbanded response this 8 ohm tweeter works well with a simple 1st order crossover (1 capacitor).
Perfect drop in replacement for a huge selection of models such as the the AR4x, Marantz Imperial 4, 5, 6, 6G, 7, 8, and 9, Radio Shack Nova 7b. Can also be used in the classic Teledyne Acoustic Research AR18s, AR28s + many others.

I've needed something like this for years, fantastic product and a lovely company to deal with. Won't be my last purchase from them
It was a nice experience to send the old filters to the UK (from the Netherlands) and get them surprisingly fast back (taking the overseas shipment into account). At first I did it wrong since I also replaced the drivers that could also be connected in a 4/6 Ohm (double coil). But after correcting and calibrating my receiver the speakers sounded great.
Thanks!
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.
