In the late 70's or early eighties I owned a pair of A D S L1290 floor standing speakers in walnut finish. They were stunning looking speakers with the black metal perforated grille. I loved that the metal grill cover was mounted with pins that pushed into holes in the cabinet. Very easy on & off. As I( remember I listened mostly with the grill covers off.
They had a very direct, clear sound and had good frequency extension (bass was emphasized).
This was when digital sound was the big buzz-word, and A D S rode those coat tails.
I drove them with a Luxman integrated amp (70 w) and they sounded very dynamic. Back in the day I didn't pay attention to things like stage,. image, air, etc. I just wanted things clear & loud. The L1290's filled that bill.
