I wanted to give everyone an update on this, I know I am resurrecting an old thread. All Bose products can be controlled via an IR remote aside from the older waveradios, but the older LS systems just need one adaptor and you canthen use any remote. I have been using IR remotes on LS-50s for some time now, I only wish I saw this thread when it was origianlly posted, would ahve saved alot of hassle eh. If anyone has questions regarding this email me.
