"Rings" & "Roys" ???
« on: January 07, 2016, 08:23:45 PM »
Hi everyone,

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.

No idea about "Roys", but could "Rings" refer to JBL 2402 (ring radiators a.k.a. bullets)?

Dave, thank you, I think you're spot on.

There were 5 or 6 mounted horizontally in a cabinet, gently arcing around for horizontal dispersion.

+1 on the "bullets".
I used a system with a 4 pack of bullets on each side to make up for the lack of top end in the JBL 2350 horns.
Crossed over somewhere around 6k or so.

Thanks Keith.

I wonder if "Roys" was an Australianism? Hopefully there'll be some 1980s pub rock soundies on the forum who'll be able to help out.
(I hope the memory hasn't gone too badly)  :-\

The "Roy Box" was indeed designed by Roy Clair. They consisted of 2 12" JBL's in a horn loaded cabinet with a wooden phase plug between the drivers. They were a little over 6db more efficient than anything else in the system and had to be turned down at the amp or crossover to balance the system. Used them many times.

Were they anything similar to the Martin "Philishaves"?

It's funny to see you listed as a Newbie (in the forum software), Rex!  Good to see you back here.

Thanks for all the console advice and help you've given over the years, too.  Couldn't have gotten the noise floors down without your expertise and assistance.

I remember folks having both 2402 bullets or ring radiators and slots in the same cabinet.  The 2405 slot tweeter had a wide horizontal pattern while the bullet is much narrower.  I actually have one laying around that I had bought intending to use for a drum monitor with narrow dispersion.

Brilliant, thanks Rex. Were they an official Clair Brothers product?, or was it a side project designed by Roy and given over to other manufacturers?
