The Monitor Audio Gold 300 5G is a three-way floorstanding loudspeaker engineered to deliver an authentic audiophile experience, melding premium driver technology trickled down from Monitor Audio's flagship Platinum II series with class-leading cabinet construction. As the pinnacle of the Gold 5G range, the Gold 300 is built to last a lifetime and to fill larger listening rooms with effortless authority.
The Monitor Audio Gold 300 5G is a true three-way design with four drivers in a ported bass-reflex cabinet. At the top sits Monitor Audio's MPD (Micro Pleated Diaphragm) high-frequency transducer, a low-mass tweeter with a surface area eight times larger than a traditional dome, delivering articulate, extended highs that remain supremely smooth all the way up to 50 kHz. Below it, a 2.5-inch (64mm) C-CAM midrange driver handles vocals and mids with precision. The low end is anchored by twin 8-inch (203mm) RDT II bass drivers, a sandwich-cone technology developed by Monitor Audio using a thin C-CAM front skin, Nomex honeycomb core, and woven carbon fibre back skin, combining incredible stiffness with low mass and natural damping.
The Monitor Audio Gold 300 5G's deceptively large cabinet houses a pair of rear-facing HiVe II ports that deliver smooth airflow and ample bass reinforcement, making the Gold 300 the ideal floorstanding speaker for larger listening rooms. Punch and dynamism are matched only by subtlety and fidelity, with effortless authority from a crisp 50 kHz at the top end to an earth-moving 30 Hz at the bottom, making the Gold 300 5G suitable for any and all listening requirements, from intimate acoustic recordings to full-scale orchestral and cinematic content.
Like every speaker in the Monitor Audio Gold 5G range, the Gold 300 cabinet is hand-finished to an exceptional standard, available in real-wood veneers and high-gloss lacquers including Piano Ebony, Piano Gloss Black, Dark Walnut Real Wood Veneer, and Satin White. The Gold 300 5G's curved cabinet walls reduce internal standing waves while contributing to the speaker's elegant, room-friendly aesthetic.

The Micro Pleated Diaphragm tweeter at the heart of the Monitor Audio Gold 300 5G uses a folded ribbon design to move air more efficiently than a conventional dome tweeter, with eight times the radiating surface area. The result is high-frequency reproduction that extends well beyond the limits of human hearing while remaining articulate, fast, and free of the harshness that can plague lesser tweeters.
Monitor Audio's second-generation Rigid Diaphragm Technology (RDT II) is a sandwich-cone construction combining a thin C-CAM front skin, a Nomex honeycomb core, and a woven carbon fibre back skin. The result is a bass driver that's exceptionally stiff for accurate piston-like motion, light enough for quick transient response, and naturally well-damped to suppress resonance. Twin 8-inch RDT II drivers per cabinet deliver deep, controlled, room-filling low frequencies in the Gold 300 5G.
The Gold 300 5G's pair of rear-facing HiVe II ports use a rifled internal surface to smooth airflow at high SPLs, improving transient response and delivering tighter, faster bass than a conventional port design. The dual-port arrangement also reduces port velocity for less audible chuffing at high volumes.
Monitor Audio specifies Pureflow silver-plated oxygen-free copper internal cabling throughout the Gold 300 5G, ensuring the highest quality signal transfer from binding post to driver and preserving every detail of the source material.
The Gold 300 5G cabinet is built and hand-finished in real-wood veneers and high-gloss lacquers to a standard typically reserved for far more expensive loudspeakers. Curved side walls reduce internal standing waves, and bracing throughout keeps the cabinet inert under load.
The Gold 300 5G is equipped with high-quality bi-wire / bi-amp binding posts, allowing you to upgrade your system over time by running separate cables to the bass and mid/high sections, or by driving them with dedicated amplifier channels for maximum performance.
A cast aluminium outrigger plinth widens the speaker's footprint for rock-solid stability and decouples the cabinet from the floor. Adjustable spikes are included for precise levelling on carpet or hard floors.
