About the Monitor Audio Platinum 300 3G Floorstanding Speakers (Pair)

Platinum 3G is Monitor Audio’s flagship range: the MPD III high-frequency transducer and RDT III drivers in beautifully made cabinets with etched inlays, in piano black, piano ebony or pure satin white.

Stereophile awarded the Platinum 300 3G Class A status, and Hi-Fi+ Highly Commended it.

Floorstanders give the fullest sound without needing a subwoofer. Start with them a little way out from the back wall, angled slightly towards where you sit, and adjust from there. We’re happy to help set them up.

Genuine UK stock from an authorised Monitor Audio dealer. Want it fitted? We install hi-fi, ceiling and garden speakers across the New Forest and the south coast. See our audio and video work.
