Monitor Audio PL300II


Standing at over a metre in height and designed to move the air in larger listening environments, the PL300 II will energise your listening across an enormous sound stage, magically studded with an abundance of natural detail. Its four driver system involving twin 8″ RDT II drivers, 4″ TLE loaded midrange and MPD tweeter, captures all the fluid tonal complexity and dynamic richness of each performance on a truly orchestral scale.

Explore the depths and climb to the heights of your music and film favourites with an effortlessness that confirms an inescapable truth: the bigger the Platinum, the more precious the prize.
