Experience the difference in a heartbeat. Surrounded by the natural audio transparency of the astonishing PLC350 II in concert with the PL300 II, or PL500 II, you’ll be lifted to the stage and compelled to take part. This is theatre on a professional scale but with the authentic presence, detail and texture that only very finest high-end audio design can conjure. The PLC350 II’s system of twin 8” RDT®II bass drivers, 4” RDT II midrange and MPD high frequency transducer will personalise the nuance of each whisper. When at least sixty per cent of the film’s emotional content is directed through the centre channel, the PLC350 II provides the extraordinary focus that transports you, exhilarated, to the end of every performance.

Platinum II’s terminal design is precision milled from solid copper with Rhodium plated conductor parts. Rhodium has been selected for its excellent electrical conductivity and resistance to oxidisation. Terminals are designed to accept a spade, 4mm banana plug or bare wire, up to 4mm in diameter (7AWG).
DCF (DYNAMIC COUPLING FILTER)
A new innovation in every driver replaces the usual rigid coupling of driver and voice coil with a pliable one. This ‘Dynamic Coupling Filter’ is a nylon ring ingeniously calibrated to be rigid up to the crossover frequency, and to act like a spring above it. In so doing the DCF helps to dampen surplus high frequency energy produced by the driver. It’s also perforated to encourage voice coil cooling and release air pressure from behind the cone for maximum driver efficiency. Result: more natural sound.
MPD (MICRO PLEATED DIAPHRAGM) HIGH FREQUENCY TRANSDUCER
Developed over many months of intensive testing and listening, the MPD High Frequency Transducer is a landmark achievement by the engineering team for Platinum II. It represents an imaginative re-working of an existing technology, transforming a successful idea into an audiophile super-driver, having greater accuracy and efficiency than ever before. Using a new, proprietary low-mass pleated diaphragm with a surface area eight times larger than that of a traditional dome tweeter, the MPD transducer works like a super-fast accordion by rapidly squeezing the pleats to produce a smooth, wide, naturally fast response up to 100kHz. As a result it sounds more lifelike, releasing the high harmonic spectrum of every note without the distortion that blurs definition.
RDT®II (RIGID DIAPHRAGM TECHNOLOGY 2ND GENERATION)
A composite ‘sandwich’ structure made from ultra-thin low mass skins, bonded to a honeycomb Nomex® core material. It is very light and very strong, meaning that it can respond with great speed without bending - just like a perfect piston. RDT II uses C-CAM® for the front skin, while the rear skin is made from a woven carbon fibre material. We discovered that the new structure reduces distortion by over 8dB above 300Hz, which makes RDT II the lowest distortion cone technology in Monitor Audio’s history.
TLE (TAPERED LINE ENCLOSURE)
The tapered and sealed internal enclosure for Platinum II’s mid-range drivers is cast from ARC material and designed to stop the formation of standing waves (internal sound wave reflections) in the cabinet. Result: greater midrange accuracy and reduced cabinet vibration for more accurate sound.
