I had a pair of L810 back in the early 80’s. I liked the sound but they were quite inefficient and didn’t sound good at low volumes so I sold them. I did have all ADS speakers in my car audio system back then with 3 huge Soundstream amps. Unfortunately, the car was stolen Dec25, 1991 and was totally stripped. There was nothing left but the car body minus the interior and tires sitting on milk crates near some housing project. That was the end of my car audio days and ADS. Also, I only had liability on the 7 year old Nissan so I lost my shirt.
Who uses ADS Speakers
I worked at ADS in The late 70s and Find they are one of the best home speakers ever.
I always loved their accuracy.
