I've never had a problem finding the wattage of the Bose L1 systems. The information has always been available, but like most PA products, you have to know where to find it. More often than not, PA systems consistently advertise their peak power - not the RMS power, which is the one that really counts. Bose, to my knowledge, usually provides information for both RMS and Peak Power. There is a HUGE difference.
Cheers,
Gary
