$50k? I'm sure they're very good, but they'd have to be really exceptional to justify that kind of price tag. If I've got my sums right that's roughly double the cost of the Revel Ultima 2 Studio 2, and that in turn is quite a bit more than many similarly sized/specced/respected passive (and in some cases active) monitors from the 'usual suspect' pro manufacturers.
Where did that price come from, Bruce? - I found Focal's website a bit obscure.
