This sub's name gets straight to the point — Focal's K2 Power subwoofer delivers hard-hitting low end that combines realistic reproduction with competition-level sound pressure. Precision engineering and hand-assembled construction make this sub a sound choice for a high-performance bass system.
At the top end of the sub, a butyl rubber surround maintains control of the cone, even during deep excursion. Focal's unique composite sandwich cone employs a structural foam central core coated with a layer of Aramid fiber on the front and a glass layer on the back side. The three layers together form an incredibly rigid yet lightweight membrane for high-quality sound reproduction with the added emphasis of thunderous sound pressure.
Assembled and inspected by hand
You can feed the K2 Power 27 KX 11" subwoofer up to 300 watts RMS without fear. This 4-ohm sub works best in sealed enclosures to produce bass that's highly accurate and plenty forceful. Focal assembles each sub by hand and rigorously inspects them for any flaws to ensure your investment performs to the high sound standards they've set.
To drive this single subwoofer, we recommend a mono amplifier rated between 225 and 450 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
