Worth the read if considering a purchase.

Conclusion So, in terms of frequency response measurement, there's no obvious split between 'pro' and 'hi-fi' among these four speakers. In fact, if anything, they fall into two rather different groups, with the B&W and Dynaudio offering a balance appropriate for nearfield use in small rooms (coincidentally, the Dynaudio and B&W have low-frequency response shapes so similar they could almost be a pair), while the Wharfedale and KRK offer something more suited to listening at a greater distance in larger rooms. The B&W is also the best in terms of resonant behaviour.

a little dated now but still interesting reading
