Why are Harbeth speakers expensive while its drivers are not.

Nice comment made by phusis...Not easy to make a speaker.  $100 for a tweeter isn't cheap by the way.  Focal inverted domes used to cost $45, morels for less than 50, dynaudio 6" could be had for $130, scan speaks woofer/midrange for less than $100... But putting it all together and making it sound its best is a long process of trials and errors.  The quality of the drivers is one thing, the expertise is really what makes a difference.

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.
