Amazingly, the speakers still sound damn good after almost 40 years. My first speakers were the ADS subwoofer set-up. My dealer (when there were such things) had people come to my apartment to check them out.
After blowing the output twice on the sub, I traded for the 980's. Weed and youthful exuberance caused too many "crank it up" episodes. Curious if you've ever done the crossover and bi-amp route on the 980's? Always wanted to try it and see how it sounded. Cheers!
