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 footswitch 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.
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 optimiza 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 105/8"(27cm) Focal speaker is equipped with a high excursion system to enable accurate and extended reproduction in the bass/ infra bass register. The 25/8" (66mm) diameter and 11/4" (32mm) 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.
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. Focal's 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 (300W RMS for the Twin6 Be and 350W RMS for the Sub6).
