As I understand it, some pro-monitors make great home sound systems versus traditional consumer audiophile speakers and some don't. Yamaha NS10s for example, are studio monitors that are ubiquitous in recording studios, but not because they are good but because they approximate the "average" system that a typical consumer would listen to the end-result of the mix on.Studio monitors are designed to be extremely neutral and accurate in a near-field recording studio environment (1-4 ft.). In an acoustically untreated home environment where a typical listening distance is more like 8-12 ft., the sonic characteristics of these pro monitors may prove even less accurate than the typical consumer speaker because that is not what they were designed for.
Nonetheless, some of the studio monitors that I have heard that would work wonderfully for stereo and home theater application would include Mackie, NHT, and Dynaudio Acoustics. Interesting enough, Dynaudio's professional speakers, save for the black vinyl finish and sans grills, are about 50% less than the price of the comparable model in their consumer line and, as I understand it, is virtually identical. Now that's a bargain if I've ever seen one!
