I'm reconnecting with my old love of live sound after many years in AV. I'm curious to know more about a couple of pieces of kit we used to use decades ago. I was very new and absolutely green to live sound those days, so my understanding of the kit was pretty low.
4560s and W bins are well known, but can someone fill me in on what "rings" (high freqs) and "Roys" (mids??) were please? I'll assume Roys were named after Roy Clair. I think at the time I used to confuse them with 4560s (hey, I was young and stupid).
Regards, and thanks for any information offered.
