Hi Scott,
I installed a pair of the WM6 last year. Beo Passive has no trouble driving them. They are really powerful which is what you need outside if you want to appreciate the subtleties of the music without having to turn them up too loud (don’t want to annoy the neighbours).
They coped easily with last year’s winter – rain, snow and freezing weather.
Hi Christophe,
I mounted the IR Eye just inside the patio doors – no trouble with the signal and no trouble with the weather. The IR Eye cannot cope with sub zero temperatures.
