DFS® (Dual Fiberglass Structure) technology is made up of robust, reliable membranes. Composed of two glass fibres braided at 90° and sealed with a polyurethane coating, this material can be used in extreme acoustic and climatic conditions... It offers efficient power handling and good bass response.

The inverted dome tweeter has been a Focal signature since 1981, offering the property of being a true micro-speaker. The curvature of the dome is much less pronounced than that of positive domes. This results in better space dispersion and very low directionality, unlike ribbon tweeters. The inverted dome tweeter therefore generates unrivalled dynamics, enabling sound engineers to precisely control the dosage of compression. The precision of the image (height, width and depth) is remarkable, making it easy to position each instrument. What's more, a waveguide has been developed to perfect spatialization and further enhance the inverted dome's very low directionality. In the horizontal plane, the frequency response is within +/- 0.5 dB. This performance guarantees an incredibly stable soundstage.
