I was on a course recently and the tutor was using an ASK A4 projector. It was pretty loud and made me feel that I'm being too picky with my Barco. Anyone know how the A4 fits in the scheme of things volume wise? HCC say it isn't the quietest or the loudest, so there must be some pretty loud ones about. I would think that is it's sat on a large, but light coffee table then It would resonate more that if it was on a pile of paving slabs. I still would like mine to be quieter but it's nice to know that it's the norm rather than the exception!
