Dean Hartley of Monitor Audio

The Monitor Audio Platinum II involves some major improvements in driver technology. Dean Hartley told me that they had moved a good way towards completion of these changes when the original Platinum Series speakers were introduced, but they felt that further improvements were possible, and they wanted to be absolutely sure they got it right, so they played it safe by going with the existing technology.

Hartley is particularly proud of what they achieved in reducing distortion. He feels that speakers are generally weak in this area, so that we may have sources and playback electronics with very low distortion, but when the signal reaches the speaker distortion skyrockets in comparison. In this picture, Hartley is showing a cutaway of the midrange driver; the plastic ring he's holding in his left hand is called a Dynamic Coupling Filter, a patented device that's instrumental in producing a more optimal driver movement.
