A/D/S L-810s were the first pair of home audio speakers I purchased in 1981, and I owned them almost 20 years till I stupidly sold them.
I also had a full car audio system with (I believe) 300i speakers, and I would often get comments such as, “this is the first car system I have heard, that sounds like a home system”.
I still use a pair of metal L-300s in my garage system and they are still going strong.
After trying to live with a variety of speakers, I bought a pair of Aerial Model 9s about 16 years ago, since Michael Kelly formerly of A/D/S is the Aerial Acoustics owner/designer. I found the Model 9s reminded me of the great tone and dynamics I remembered from the L-810s. With Michael’s help, I have migrated from the 9s to a pair of LR5s with a pair of SW-12 subs and will probably never change, except maybe to add another SW-12 sub or two.
I really enjoy the great tone and dynamics of the sealed box LR5s and agree 100% with Michael Fremer’s review of those speakers.
