Apex is a 'flagship' range of versatile compact speakers, which blends elite styling with the advanced technologies of our award-winning speakers. Twice named 'Best Style Speaker Package' at the What Hi-Fi? Awards, Apex delivers high quality audio with designer appeal.


The cabinets are made from rigid die-cast aluminium coated in a sumptuous black metallic or pearl white metallic high gloss lacquer. The C-CAM® bass driver, which has been engineered exclusively for Apex, uses high performance RST® dimpled cone geometry for added rigidity. Drivers are secured to the cabinet using a single central through-bolt fixing, which acts as a cabinet brace to reduce resonance.

Innovative high quality metal wall brackets supplied with the A10 and A40 are custom designed to make installation quick, easy and secure. When installed, the speaker can be tilted precisely for the best stereo or surround sound imaging. A stylish, internally pre-wired floor stand for the A10 is also available.

Due to its precision-engineered voicing, the Apex range can be mixed in any combination to match room size, shape and acoustics, delivering the audio range and quality of much larger hi fi speakers in an extremely stylish and space-friendly way.



 Bracket allows for forward and backward adjustment plus a 22.5º tilt upwards and downwards for optimum setup.

Can be used vertically or horizontally, as a centre or surround channel

Hive II port Technology

 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.


Gold Dome C-Cam

The gold dome tweeter is formed from a ceramic-coated aluminium/magnesium alloy, gold anodised to a specific thickness for ideal stiffness and damping characteristics. Its new profile and surround geometry have been developed using advanced modelling tools, to provide the optimum qualities for accurate sound reproduction. The new design moves the first order of breakup to beyond 35kHz, producing a linear response way beyond audibility, which matches the wide frequency bandwidth available from HD music and cinema sound formats.

The gold dome is thinner, lighter, more rigid and therefore more efficient than domes made from other materials which are prone to distortion in the audio band.
