Product Description

Focal SW 1000 Be active subwoofer is the redesigned version of the Electra Be subwoofer to ensure compatibility with the other loudspeakers in the Sopra line.


It is equipped with a 13" (33cm) "W" cone speaker driver (high rigidity for no distortion, even at high volumes), a high-power 600 W RMS BASH® amplifier and a front laminar port (no dynamic bass compression).

Digital Processor

The 24-bit digital processor (DSP) offers a large control panel with settings for adapting the sub to various listening rooms. The SW 1000 Be offers very high performance with a bass cut-off frequency of 18 Hz and an SPL of 118 dB

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.
