Are Bowers and Wilkins speakers overpriced?

All speakers are overpriced - way overpriced!

The trick is to find the discounts.

I just bought a pair of the best sounding speakers made at a $10,000 discount - about 50%.

Can’t share the type or source - must maintain the confidence - so, I can preserve the relationship.

But, it serves to make the point.

That’s a bummer you can’t appreciate the diamond tweeter. It’s pretty stunning when toned down a bit with tubes. I can’t get enough!

I don't think it's inappropriate to ask if speakers are overpriced, if you answer in relative, rather than absolute terms.
For instance, most new B&W's seem overpriced compared to several different models of used / vintage speakers.   I recently purchased a used pair of ADS 1290's that sound just as good (and perhaps better:  not as bright) as a pair of B&W 804's, at a fraction of the price.  

I liked my 803's.  Very natural sound. They had very good resale value too.

Yes they are overpriced. All speakers are.

Disagree.  I bought a pair of used 1984 Klipschorns in 2001 from audioclassics.com for $3,000.  Fair price...good deal. 

I could never had made a pair of speakers that good for the same price in research, materials, time, and effort.

Then, in 2019, I bought the Volti Audio upgrade package for the Khorns for $4,800.  I have yet to install the upgrade, but I have a feeling that it will be difficult to achieve a better sound for any price once they're dialed in.

All speakers are not overpriced.
