Much of the monitoring in the studios in your link, are relatively cheap, but sound good.
I agree they are extremely good value if you can accept the awful and purely functional aesthetics (no nice elegant shapes and no nice veneers). Much of the expense in consumer speakers goes to expensive cabinet work and veneers - the goal of most designers is an eye catching piece (typical manifestation: tweeter on top like a cadillac hood ornament, and cool looking shiny metal drivers rule) - designers are often the cheapest possible drivers that still sound good enough (better than best buy) at modest levels.
However, most consumers are looking for something they can be proud to own (WAF happy too) and are therefore not overly concerned about the sound quality, which is often secondary to the aesthetic desirability of the component. By aesthetic measures, pro gear is EXPENSIVE and rather poor value...
