From some web-site:
The sound contractor for this festival was Malcolm Hill. Hill Audio was a well-known native company based in Hollingbourne, U.K. In the great Tradition of the Times the company was named after, owned and run by Malcolm Hill. Malcolm and his employees designed and purpose-built a great deal of the equipment in his own shop. Speaker cabinets, power amplifiers and mixing consoles were all custom made and proprietary.

From Prosoundweb:
I guess it works with the Hill PA system(3 12", 2 10" and 1 2" motor on a 60x90 horn and the sub was another 12" in a short box that has the same footprint as the HI/Mid box.

I think I'm safe, but it's almost impossible to tell these days, with all of the participating nations in the patent system.

I ran into a Japanese patent on one of my other applications, how in the world does one search for that?! Doesn't seem to be quite right to me.

Sure, let's check out the possibility of a get-together. If you're not too far north, and we have some ideas to kick around, it could be fun! There must be coffee or beer. Or both.

Wait a few weeks, and we'll have a variety of "things" to listen to!
