The first completely Rat designed system. The
18" sub was tuned at 20 HZ. The PA sounded quite good, especially
compared to the other systems of the time. Nearly everything
else out there had a big horn in front of it and if they could point
the speaker backwards and bounce the sound off of a bunch of wooden
panels before it came out of the cabinet, it was considered a good
thing. The down side of this system was that it was not as loud
as the horn loaded competition and everyone told us that it will not
work in larger rooms. We began designing and testing various
protection methods to increase system volume and reduce component
failures. With the gradual acceptance of this PA in the local LA area
we (Brian and Dave) were finally able to quit our jobs at Hughes Aircraft
and dedicate our full time to the growing world of Rat.
