Focal 100 IWLCR5

PRECISE ACOUSTICS

100 IWLCR5 features an adjustable inverted dome tweeter. Its 13 cm loudspeakers feature Polyglass diaphragms for excellent damping and well-defined midrange. Correctors are used to equalise high and mid frequencies, for an ever more appropriate acoustic response.

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.
