Hello Paul,
The M22ti's are extremely neutral and uncolored--possibly the most transparent speaker available anywhere near its price. It's even more neutral than the more expensive Paradigm Reference Studio 20, which, although very close to the M22ti, still has a slight hump in the 100 - 200 Hz region.
It's my experience over the years that some domestic speakers like the M22ti are far more neutral and accurate than some of the "professional" studio monitors, whose frequency responses are quite wonky.
Regards,
