I had a pair of ADS 320i speakers in the B-pillars of an '82 Trans-Am T-top with a Nakamichi head unit. The stereo sounded great. The car was fun for a while but was really just a bucket o' bolts.
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.
