Focal Sopra Surround Be Dipole Speaker

Focal Sopra Surround Be Dipole Speaker

Key info

The Focal Sopra Surround Be Dipole Speaker features an exclusive “Bi/Twin” design with twin inputs, enabling the loudspeaker to be used both in 5.1 bipolar mode or 7.1 double mono mode. This feature avoids having multiple surround loudspeakers in your Home Cinema.

Neutral Inductance Circuit

The precision and detail of audio reproduction depends on the stability of the magnetic field. Neutral Inductance Circuit technology finally enables to master it in order to limit distortion and to offer a very high-definition and an unequalled dynamic to sound.

Tuned Mass Damper

TMD technology consists of optimising the suspension profile which controls the resonance in order to drastically reduce distortion and increase the definition of bass and midrange.

Infinite Horn Loading

The “IHL” system enables to load the Beryllium tweeter respecting the compactness demand of the speaker. The rear wave of the tweeter is delicately and gradually absorbed to avoid any distortion. The treble definition is pushed to the maximum.

Mastering the build

Sopra’s cabinet was designed in our cabinet-making facility in Bourbon-Lancy (Burgundy, France) using the same manufacturing process as for Utopia. The inside of the cabinet has no parallel side panels, and small Helmholtz resonators have been added to the lower section to prevent vertical standing waves.

Gamma Structure

The 69mm sandwich-machined front panel uses the same principle as ‘Gamma Structure’ to provide inertia and damping. Its density gives it the inertia necessary to provide a stable mechanical reference for optimal definition. We chose glass as the material for the base of the loudspeaker to provide floor coupling, using spikes, which enabled the fastest propagation time possible, thus eliminating all halo effects in the bass.
