Why in that case do all retailers, when you audition a piece of kit, feel compelled to blow your eardrums out by cranking it to very high volumns?
It's possibly the same thinking as in many other retail fields, they're probably trying to create an initial impact. Much easier to do this with higher volume. They'll be aiming for the 'wow' factor.
I imagine it's also an attempt at showing the customer the potential of the product, and it's tricky to do that, especially with cinema systems, at low volume.
This is not aimed at one retailer in particular, but most of the ones I've visited over the years. It seems to be a prerequisite of most, including the bigger chains.
Thing is, if they do it everywhere, then it's probably the right thing to do. They can't all be wrong
Even if we don't really like loud demo's, and I for one don't, I'd say it's probable that the majority of the buying public do.
If you think of the big high st chains especially, they all plaster the wattage figures all over their brochures. Their research must tell them that this is an important stat to their customers. So if the majority of their customers equate wattage with quality, blasting a demo at them will demonstrate this perceived 'quality'. If they want power, a loud demo proves that their choice of system has it. The good folk of this forum know that power doesn't necessarily equate to performance, but your average Comet buyer maybe doesn't, as Joel mentions.
Also, at a recent demo I had, the chap set it up at a fairly low volume, then left me to it. I had to go and ask if I could turn it up a bit. Unfortunately, many customers don't ask things if they're uncomfortable, they just smile and leave, rather than asking a question they may feel is silly. I guess many customers, if left to their own devices, would feel more comfortable turning the volume down than up, for fear of doing something wrong.
Sorry, rambled on a bit, but I've had many years in retail, and learned that many of the things that seem strange to the punter make perfect sense to the retailer
