In the early 80's, when I was more active in a sound production company I own part of, we purchased a bunch of Turbosound equipment, which was what the producers of most of the national touring acts required. They were expensive but we had to get them to secure the high end business. We used them at venues with up to 25,000 people. Some are still in use, but I'm sure something else is the "equipment of the day" (now, I just sign the checks).
They were rugged (early powered speakers)
and sounded GREAT! If it's the same company, an the price is right, you probably can't go wrong.
Regards,
Russ
