Focal 100 IC6ST

PERFORMANCE

The loudspeaker features a compact, directional tweeter and a Polyglass cone driver. A crossover facilitates off-axis listening and reduces the “shower effect”.

EASY INSTALLATION

Simplicity of installation and design are key criteria: robust mounting brackets and magnetic grilles reduce installation time. The shallow depth of 100 Series products ensures discreet integration.

TECHNOLOGIES

Polyglass membrane

Well-defined mids

The diaphragm, the key component of a loudspeaker, is at the heart of our acoustic engineers’ research. Polyglass technology, exclusive to Focal, consists of applying fine glass microbeads to a cellulose pulp cone. This process reconciles the excellent damping of paper with the rigidity of glass. The stiffness index is almost 10 times that of polypropylene. Adjusting the mass-rigidity-damping ratio results in a remarkably linear frequency response curve, right from the membrane design stage. This innovation also significantly increases definition in the midrange register.

Inverted dome Tweeter

Optimum space dispersion

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 spatialisation 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.
