Monitor these monitors – It's the new 4-square Platinum 3G range celebrating Monitor Audio's 50th anniversary. There's a new 3rd-gen AMT tweeter and composite dynamic cone which surfaces a Nomex honeycomb core with ceramic-coated aluminium plus dual 90°-offset carbon fiber skins. Its new motor system exploits Neodymium magnets and an underhung edge-wound voice coil. Other improvements are the elliptical crossover promising perfect time alignment across the filter transition; and piano ebony or black plus satin white finishes. The 300 floorstander is €14K/pr, the smaller 200 €11K, the 100 monitor €5.5K and the C250 3G center €4'750/ea.
