Saw that, was hoping you'd snagged 'em. Still, if you find a pair that says "untested" w/o adapter, beware speaker rot  .  .  .

.  .  .  especially so if a power adapter is listed at around the same time by whomever  .  .  .

.  .  .  just sayin' :

Any suggestions for new driver replacements would be appreciated. IIRC, the drivers in the AD1s are pretty good sized as compared to the Altec-Lansings I have in almost identical packaging. I imagine adapting a two decades more modern design for a smaller driver might yield better sound than the originals?
