Did the Peavey HDH system incorporate any thermal limiting? Or was that more of a servo feedback sort of thing? I remember it being likened to a Meyer system a the time.

I had 2 types of those for a very short time. One ( again way back cloudy memory ) was a generic Sub ,Mid and Top type. DSC Sub or something like that. Like others have mentioned there was a sense line that measured , I'm guessing , the voltage coming from the speaker and moved the crossover point and I think some limiting. Any 1/4 inch speaker cable would work. I had my SP2's and subs on it. The other one was for a Horn,Mid-High,Sub system. I remember 4 22A horn drivers in the top. A 12 inch or 10 inch midrange and 2-18 sub using a slight Manifold arrangement. There was pre made cables that went with the system. I know those in my area who had them and drove them hard still burned a lot of speakers but if you just flickered the lights on them I could run the system for days without an issue. I think they really increased the RMS value if you were out pushing hard for a long time.

A quick look and I found the DSC Series 23 and HDH I had.
