Why are Harbeth speakers expensive while its drivers are not.

Well this is interesting. 

It seems to obvious to suggest that perhaps those far more expensive drivers would not...
A. Sound as good as the ones Harbreth uses.
B. Match the crossover.
C. Are as reliable.
D. Are as musical sounding.

Sorry for the mix-up Doug!

All great points above. I can only add to what davt said about what the market wll pay (or bear). It would scare the hell out of me to be a speaker manufacturer in this day of countless manufacturers. Anyone can go out of business at any time. If a company such as Harbeth marked their product up 1000 %, I wouldn't hold it against them. It simply doesn't matter how much it costs If the public isn't willing to pay the retail price. If Harbeth believed they could sell 10000 speakers a year CONSISTENTLY, they would be willing to sell for a lot less. Another factor comes into play then; would they really want to see their speakers in BestBuy! Scary, scary, scary.

One further thought. I wouldn't expect a speaker manufacture to change out drivers overtime the driver company called to say they have a newer " better sounding " driver available. 
Further the speaker manufacture, Harbeth in this case would have to change the model or put a II after it to designate the change. 

Price is based on the perceived value of Harbeth speakers by customers and not by how much they really cost.
