Beautiful work, Ruben! The piano gloss BEM one is just awesome!
Just to fill in your list of finishes (SAC finishes):
Rosewood
Black
Birds Eye Maple
Macassar Ebony
There were versions done in both satin and gloss/piano in all four. If my memory is still good, the satin BEM was very limited, maybe to just unfinished cabinets at the very end of the run, and the ebony was only a very few pairs in both finishes, complete speakers, with the gloss ebony in rarity just behind the satin BEM.
There are a few other SAC finishes from back in that day, but they weren't run in the LS series, best I can remember.
Between you and Danny, cheers on a job well done getting this project finally "done".
