Platinum II

January 2016

Platinum II - Stars of CES 2016

"Monitor Audio's current Platinum series has been around for the best part of 15 years, and at CES 2016, the British loudspeaker manufacturer officially launched an all-new Series II.

The revised range includes new standmount and floorstanding models, all of which feature a brand-new MPD (Micro Pleated Diaphragm) tweeter and improved crossover design."
