Standing at over a metre tall the GX300 is a majestic three-way floor-standing loudspeaker comprising twin 6.5” bass drivers, a single 4” mid-range driver and a high frequency ribbon transducer. With such an impressive complement of drivers, the GX300 has the power delivery and scale required to fill the largest rooms with jaw-dropping dynamics as well as the finest musical detail. Extending from below 30Hz to over 60kHz, its frequency range is among the widest available from any speaker, irrespective of price. Sublime fidelity, peerless build quality and exquisite design distinguish the GX300 as a future classic.

Refined over many years by Monitor Audio, Ceramic-Coated Aluminium/Magnesium is used as a driver cone material for all our speaker designs from the mid-market models up. Originally developed by the aerospace industry for jet engine components, C-CAM's properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. C-CAM bass drivers are able to resist the bending distortion imposed by sudden and extreme bass excursions to reproduce very clean, deep and dynamic bass frequencies. Conventional cone materials are more likely to flex in operation, producing a significant level of audible distortion.
Monitor Audio's proprietary ribbon tweeter design uses an ultra-thin sandwich of C-CAM alloy suspended in a powerful transverse magnetic field of high energy NeFeB rare earth magnets. The ribbon serves as both voice coil and radiating diaphragm, with every part of the ribbon driven directly and simultaneously without energy storage. Having a mass of just 18mg, its diaphragm is able to start and stop in an instant, producing a transient response capable of defining the leading edge and natural harmonic resonance of complex musical sounds. Specified to reach ultra-high frequencies up to an elusive 100 kHz, Platinum’s magical ribbon tweeter will reproduce with ease every last nuance and detail from vinyl, CD, DVD-A and SACD, together with the wider bandwidth of Blu-ray.
Ceramic-Coated Aluminium/Magnesium is a material originally developed by the aerospace industry for jet engine components. Its properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. In manufacture, aluminium/magnesium alloy undergoes a three-stage stress-relieving process to remove surface deformation and molecular weakness. Once formed, the alloy cone is subjected to a high temperature anodic coating process in which a layer of pure ceramic alumina is depleted onto its surfaces to a depth of 50 microns, producing a completely rigid sandwich of alloy and heat-dissipating ceramic material.
Conventional cones are liable to flex or twist in operation, producing a significant level of audible distortion. C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range. C-CAM tweeters and woofers share an audible consistency producing a smooth transition of frequencies and a sense of realism and cohesion in the soundstage.
A new type of port technology which uses a straight rifled design to accelerate air flow and reduce turbulence. HiVe II technology has the ability to move air in and out much quicker than a conventional port, the result is fast powerful bass coupled with superior transient response.
The Rigid Surface Technology (RST) cone profile is inspired by the Japanese art of Origami, which demonstrates how a very light material (like paper) can be strengthened and made more rigid by making small and precise folds on its surface. Monitor Audio has applied this principle in designing the CAM/RST cones for the GX and RX ranges. Developed and perfected using sophisticated computer modelling (Finite Element Analysis), the GX mid and bass driver cones have been strengthened by a series of radial ribs; the RX driver cones by a pattern of dimples. Our simulations have proved that RST significantly increases cone rigidity, allowing the radiating surfaces to resist mechanical bending forces, which can twist the shape of conventional driver cones to produce distorted sound. The strengthening effect of RST means that we can use thinner, lighter and more responsive C-CAM cones, which provide speed and accuracy while offering greatly reduced distortion. The RST patterns also help to displace standing waves that can propagate on the cone's surface.
HiFi+ GX300 Review
In the current issue of HiFi+ (on sale now) the big brother's of the Gold GX range - the GX300s are under a full detailed 3 page review and we weren't disappointed with the results:
"These are good, unfussy loudspeakers that don't force the listener into a bout of audiophilia nervosa. Buy 'em, keep 'em, love 'em!"
"Ultimately the Monitor Audio sound is one that is big and impressive. It casts a wide sounstage, with full-sized, solid instruments in their own sense of space within that soundstage. It goes loud too. All this, combined with the extension of top and bottom, gives you a sense of immediate impressiveness".

Setting the Gold Standard
Home Cinema Choice magazine gives their verdict on the Gold GX Series with an all round 5 star approval across the board.
In the latest January 2012 issue of Home Cinema Choice magazine our Gold GX series was reviewed, tried and tested for performance, design and features and then rewarded with a fantastic overall review of 5/5 stars across the categories.
Here's a snippet taken from the full review "Running through Pirates...had me scribbling all sorts of notes ('huge, rich, foundation-shifting bass with power and grip'; 'nil flex on the 15in piston'; 'Exciting, musical and able to create a sense of scale'), but all you need to know is that I loved this system with a passion."

I already own a pair of GR60s and just heard the GX300 in my local show room. When it comes to Monitor Audio, I am a believer! ...Steve T. Barefoot Recording Studio

Owned a 5.1 GX300 set for a year. Outstanding clarity and gorgeous appearance. Phenomenal sound. GXFX speakers are dropping jaw. Extremely happy with my selection.

I have Gx 300 and pioneer lx85 amp and chord signature speaker cables and the sound is nice with my system.

I purchased my GX300's in piano ebony and all i can say is that they look gorgeous and sound even better, sparkling top end, clear detailed mid range and deep articulate bass, stunning speakers!

Very detailed with good stereo imaging. I disagree with some reivews out there saying these are bright. GX300's are warm and smooth. The bass was surpringly tight and deep. Solidly built and dreamy to look at.

I couldn't be happier with my GX300's. They have a startlingly transparent and detailed sound. They are unforgiving with poorly recorded material, but they really shine with high-res recordings. Their stereo image is razor sharp and their soundstage is deep and layered. The ribbon tweeter adds incredible detail and clarity to the high frequencies. They are also beautiful to look at. I can't say enough good things about them.

Owned a pair of these for approx 1 month so still not fully run in. Phenomenal sound& beautiful build quality; image like nothing else on this side of £10.000+ tight bass & stunning mid range gx 300s are a bargain at this price almost as good as platinums but without the ruthless exposure of front end flaws !
