Focal Sub6 Professional 11" Subwoofer

The Sub6 is a large volume cabinet design, equipped with an 11" woofer and a rear laminar port. This configuration guarantees bass linearity whatever the intended SPL. The control board is extremely versatile, with connectivity which allows a 2.1, 2.2 and multichannel use via the L/R inputs and outputs and the LFE.

The numerous settings such as the high-pass crossover dedicated to monitors, the adjustable phase and level control provide optimum coupling with the Solo6 Be and the Twin6 Be monitors. And finally, a small, but important point: the foot-switch input. It enables one to connect a pedal to deactivate the subwoofer and the high-pass crossovers on the outputs that supply the monitors. This simplifies and greatly improves control during the different stages in monitoring.

Connectivity for Optimal Integration

The Sub6 monitor loudspeaker was developed to perfectly complement the acoustics of Focal monitoring loudspeakers. It features numerous settings such as a stereo high-pass crossover (75Hz - 100Hz) specific to left and right loudspeakers, a configurable low-pass filter with mono summation, a phase inverter, adjustable phase and even a MUTE switch. The various connectivity options enable use in 2.1, 2.2 and multi-channel modes, via the L/R inputs and outputs, and the LFE input.

Footswitch - The "Little Extra" that makes a difference

A major advantage of the Sub6 is its footswitch input. This allows you to connect a footswitch which cuts off the subwoofer and deactivates the high-pass crossovers on the outputs powering the monitors. The footswitch input enables you to compare the sound of a 2.1 set-up (Sub6 filtered + monitors filtered by the Sub6) with that of a 2.0 set-up (subwoofer deactivated + monitors in wideband mode). The two versions can be compared instantly, simply by pressing the footswitch: you barely have to move a muscle.

The "W" Cone

Focal has been developing the technologies of composite sandwich cones for more than 15 years. The "W" process ( Glass/Foam/Glass ), used on the SM11, SM8 and SM6 lines, provides a true optimization of the frequency response by fine tuning of mass, rigidity and damping parameters. The balance between these 3 fundamental and often contradictory parameters is at the base of the outstanding sound neutrality of our speakers.

The 10 5/8"Focal speaker is equipped with a high excursion system to enable accurate and extended reproduction in the bass/ infra bass register. The 2 5/8" diameter and 1 1/4" height voice coil ensures a perfect mechanical coupling and a total control of the driver even at high sound level. The magnetic construction made of double ferrite and large field and back plates offers high symmetrical magnetic field to keep dynamics even at very low frequency.

A Custom Designed Amplification Stage

Designing an amp to be integrated inside a speaker requires a very different set of rules than for a traditional amp. Speaker size and cooling concerns are often in contradiction with the high quality and high power requirements of a sonically transparent speaker. Our engineers used the BASH® technology to develop the bass/medium amplification circuit for the SM6 professional line of speakers. This was the only way to exploit the best of class AB style circuits ( for exceptional quality ) with a class D type yield, which is crucial when housing a 150W RMS circuit in such a small space ( 300 Watt RMS for the Twin6 Be and 350 Watt RMS for the Sub6 ).
