Hi Miami Mo
I have heard them many times, (Mainly 2 used in stereo) as have others and the views are mixed, however one thing I have noticed is that those that take time to set up the speakers for the venue and adjust them during the performance (Bose supply remotes) to suit the music, make them sound totally superb,. (Forget your Makies etc, they sound like castrated dogs) but those that do not set them up correctly, make them sound like a wind up gramophone horn with a sock stuffed in it. (The Bose are more critical of setup then standard type speakers)
