dual cone speaker with grill aWhen it comes to speakers there are plenty of options and we have relationships with various companies in order to provide our customers with choice and quality.

In the main we find that the Monitor Audio in-ceiling speakers are very popular as they are of excellent quality, reliable and affordable and this is therefore the range that we actively promote and include in our website. 

However if you are looking for a different solution please contact us and we will be more than happy to help. 

Presented with a myriad of choices, below you will find some details on the Monitor Audio speakers we stock, and in the information section we have a page that explains and describes all of the component parts of a speaker so that you can make sense of any technical specifications, it is called speaker terminology.

We hope that we have provided you with enough information to consider your requirements and if you would like an idea on pricing please don't hesitate to contact us.

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.


Metal Matrix Polymer driver cones have a polypropylene base loaded with metallic particles to offer a rigid and responsive structure. They are manufactured using a sophisticated high-pressure injection process, which modulates cone thickness at critical points to optimise stiffness and consistency, resulting in a superior sonic performance.
