What makes an expensive speaker expensive

I have had this discussion recently with a lot of my audio friends.  I asked them about paper cones and the cost of speakers that use them.  It's funny, but to a person, they feel that some of the top name companies who are still using paper in drivers that are not costly, are just charging a lot due to their name.  I brought up the fact that the cases can be expensive.  I'm personally on the side of not loving paper as I hear the distortion they have as they break up a ton.  I fully respect folks who love them, but they aren't for me.  I tried to take up the cause of the cost of a specific brand that utilize soft domes and paper drivers.  Even a couple of dealers I'm friends with have joked about the true cost of the drivers in the 50k plus speakers.  The bottom line is that there is a market for speakers that are costly or the companies would probably just go under and thats not happening in most cases.  We all like different sounds and there are plenty of companies who give us all what we want.  

Hi Ctsooner,
We can definitely agree that listening impressions are simply subjective and personal.  In this case Analoguvr posted comments that I could truly relate to. Coincidentally he and I also prefer   SET amplifiers so we certainly hear in a similar manner it seems. We're all fortunate that the High End audio market has products to suit a multitude of tastes. 
Charles, 

What are the prices of vandersteen replacement drivers? Who makes them? You say paper cones have a lot of breakup? Can you please give example of driver and speaker model? I do not regularly see it as a direct problem for end user. I also looked up Sabrina 3 as possible example, but did not see real evidence of that on stereophile’s "spectral delay" plot. May be I do not know what you mean. I would bet the damping characteristics between particular carbon fiber and paper driver models vary and possible overlap much as their costs.

You may be interested in Reference 3a driver implementation if you have not heard of them already. They have carbon fiber driver "hyper-exponentially shaped to avoid cone break up modes". Its run full range.

Hi ohlala, 
I didn't address ctsooner's comments about paper cone "breakup" as I want to avoid going too far off topic  (which is easy to do ). No matter the driver cone material of choice there's always a hierarchy of quality and performance.  Designer talent, knowledge and most certainly implementation are the determining factors. 

Paper cones done poorly will have obvious failings, if done right they'll sound wonderfully natural. Carbon fiber, aluminum, beryllium  etc.  The same principle holds true,  there's good and bad examples of all materials.
