Focal Sub One Active Dual 8″ Subwoofer at a glance:


Focal offers Sub One, a subwoofer with 200W RMS of power, for producers and sound engineers with higher sub-bass requirements. This long-excursion, high-efficiency subwoofer guarantees an optimum coupling with the Alpha Evo range as well as the Shape line of monitors thanks to its accuracy and extremely low distortion. The speaker drivers include a special double-skinned Slatefiber cone, which is perfect for a subwoofer since it provides even more rigidity. Finally, because to its shallow depth and big vents on the front panel, Sub One may be placed under a desk or along a wall with great ease.
