I've probably said this before, but like other well liked smaller UK speaker brands and taking inflation into account, ATC are practically 50% more expensive than they were say, twenty odd years ago. I worked it out that my wife's favourite 20 'Classic' in passive and quite heavy stand mount form and wooden veneer, is now £3750pr when I worked out they should be a grand less in inflation terms. Pro Business did scale back as big studios closed and the need for large twin 15" soffit monitors declined and maybe there became a need to charge more per box to survive. Other more domestic Uk brands have just been caught up in the far eastern audiophile market where the price tag is as if not more important than any performance virtues. Some UK dealer chains demand more profit margin as well, so we buyers suffer.
ATC's bigger models do seem built like brick out-houses though and this can't be cheap to engineer. Compared to some inferior domestic lines costing far more, they're still bargains, if out of my range now.
Mind you, the average speaker tested here is often available online with smaller supplier margins I feel and the march of affordable technology means we don't need to spend so much to get a great sound and performance at home now.
