Thanks to the new ‘M'-profile 'W' sandwich cone combined with the TMD® surround, it is capable of covering an extremely broad frequency range, of playing as well low to bring you excellent dynamics as it is to climbing up to the high-mids to make a perfect transition with the 3.5WM midrange or our TBM tweeter.
'M'-profile 'W' sandwich coneThe new, patented, ‘M'-profile cone is the result of many years of research and our expertise in materials and their geometry. The innovative ‘M’-profile, made from a single piece, means it is incredibly rigid and perfectly combines the three criteria essential for creating an “ideal” speaker driver: rigidity, lightness and damping. The result is an extremely linear frequency response, a low distortion rate and better sound dispersion.
Upon listening, this cone delivers striking realism and level of detail, that transports you into the heart of music.
Originally developed for the Sopra line of high-fidelity loudspeakers, our TMD® (Tuned Mass Damper) surround has a unique profile, designed to better control the effects of resonance and to drastically reduce the distortion associated with deformations of the cone. The speaker driver takes advantage of this patented technology by spreading better defined and very realistic midranges’ frequencies.
The progressive spider used on all our Utopia drivers is built around a progressive section that reproduces all the impact of the bass whilst optimising the linearity, precision and dynamics of the sound.
