Design Ideologies
The Sub Utopia EM Colour Evo subwoofer is the ultimate Utopia building block. It is the perfect complement to the Viva Utopia Colour Evo multi-channel loudspeaker, and matches all the other models in the range, both sonically and aesthetically. An excellent audio product for music lovers and those who aspire to perfect listening quality.
The Power Within
The Sub Utopia EM Colour Evo is a passive version without electronics, organized around a 330 mm subwoofer with an electromagnetic motor that propels the sound through a powerful loudspeaker. The resulting frequency response is 22 Hz to 500 Hz.
The Stackable Option
One secret behind the Sub Utopia EM Colour EVO is that they’re designed to be stacked. This allows Focal to match every power and bass requirement. The power of EM technology, but with Utopia class
The Focal Know-How
This subwoofer benefits from Focal’s Utopia technologies: “W” technology woofer for defined bass, large-diameter double front port limiting airflow noise and distortion, anti-vibration Gamma Structure.
Refined Finishes
The Utopia III Evo range all stand out with their contemporary styling and distinctive silhouettes. Metallic colors inspired by the automotive world and timeless wood finishes complete the look of these loudspeakers.
The Best Components
Perfection is born of detail. Every component has been carefully selected. Large cross-section cables ensure transparency and naturalness. The acoustic wadding lining the interior of the subwoofer is dense, for controlled, precise bass. The rigidity of the cabinet, enhanced by machined aluminum rings around the loudspeakers; reinforces the overall coherence of the acoustics.
Design Features
The rich heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies incorporating the latest technological advancements. Below we delve into some of these in more detail.
The “W” Membrane
The provides perfectly defined midrange and bass. By developing and manufacturing its own membranes, Focal pushes the limits of innovation in acoustics. The sandwich “W” membrane of the loudspeakers plays an essential role in sound reproduction. It consists of two sheets of glass placed on either side of a central foam body; a sandwich construction that enables us to master the three key parameters of a good loudspeaker: lightness, rigidity and damping. This flagship membrane of Focal know-how perfectly optimizes the frequency response curve, providing low distortion and total listening transparency. Sound is the ultimate in precision.
TMD Suspension Systems
This stabilized surround eliminates vibrations. While Focal engineers are experts in the development of exclusive diaphragms, they also innovate in all the components that make up the loudspeakers, such as the surround that connects the diaphragm to the frame, the performance of which must be mastered. Introduced in 2015, Tuned Mass Damper (TMD) technology with harmonic damping consists of the addition of finely positioned toroidal weights to stabilize the surround for even greater sonic neutrality. This technology enhances the midrange and the erratic behavior of the surround between 1 kHz and 2 kHz.
The Power Flower
This equated to more energy and optimized ventilation. The performance of a loudspeaker is directly related to the magnetic energy transmitted by the magnet. To develop high-performance woofers, our engineers created the multi-ferrite magnet, or Power Flower™ technology, which brings together several stacked ferrite rings distributed around the central core. This technology combines very high magnetic energy transmission, for tenfold power handling, with optimal cooling of the loudspeaker: the spacing between the blocks allows free circulation of hot air, ensuring unrivaled ventilation of the coil. As it heats up less, it no longer represents a limitation on power, even after prolonged listening at high sound levels. Another advantage is that the coil is decompressed because it is totally open-back to the outside: distortion, linked to mechanical compression phenomena, is considerably reduced. This technology has been an exclusive Focal signature for many years.
Gamma Structure
An anti-vibration cabinet is important. As the surface area of a loudspeaker cabinet is greater than that of the loudspeaker diaphragms, it can radiate sounds that are distorted by the resonances of the cabinet structure. This alters reproduction and blurs the sound image. To prevent such “interference”, it is essential that the cabinet is as inert as possible. At Focal, craftsmen use MDF (Medium Density Fiber) to achieve this inertia. This stable, heavy structure is anti-vibration. It has been optimized by vibratory mapping of the loudspeaker walls to reinforce or modify the structure wherever a weak point appeared.
NIC Technology
For very high-definition sound, control of the magnetic flux circulating in the loudspeaker is essential. Focal’s astute acousticians have created a magnetic circuit of incredible stability, guaranteeing perfectly controlled sound: Neutral Inductance Circuit (NIC) technology. This patented technology resides in a Faraday ring whose dimensions, material and positioning are optimized to make the magnetic flux stable and the sound highly precise.
