I have a pair of these (old) speakers, plus a full Acoustic Research

condition, considering they have all been inn storage for the past 7
years or so.
Only problem is that the tweeters on both speakers have stopped working
and I have determined that it is the crossovers that have failed.

Anyone have any idea where I could get these replaced/fixed? I can't
even track down the web-site for Acoustic Research

Whatever exists currently for AR will have little or nothing to do
with the original AR speakers. Try this site for info/help on the
classic models:
