Product Overview
Power
The Sub Utopia EM Color Evo is a passive version without electronics, organized around a 33 cm woofer with an electromagnetic motor that propels the sound through a powerful loudspeaker (frequency response 22 Hz to 500 Hz).
Up To Three Subwoofers
The secret behind the Utopia Sub? It's designed to be stacked (up to 3 subwoofers) to meet every power requirement. The power of EM technology, but with Utopia class.
"W" Membrane
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.
Gamma Structure
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, that it is not emissive. At Focal, we 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.
