Anther manufacturer is catching up to B&O's basic technical design for its speakers: Q Acoustics, a moderately-priced brand, is now selling an active (i.e. amplified), wireless transmitter version of their speakers, with a boundary compensation switch, a Left/Right switch, and even a tripod-ish stand! Alas the speakers are hideous; but the stand is a nice piece...

It's high time for BeoLab 18's to get a microphone jack and the active room compensation available in the 50s and 90s -- just to stay one step ahead! [Edit: Yes, Sonos has had all these things for a few years now, but their manufacturing budgets keep their speakers out of the premium-quality range.]
