FOCAL K2 Power Series 10" 4-Ohm Shallow-Mount Component Subwoofer -SUB 25KXS
Same great bass in less space
Focal's SUB 25 KXS subwoofer combines the great features of their K2 Power Series subs with a practical shallow-mount design to deliver the solid, hard-hitting low end you expect from Focal. Precision engineering and handmade craftsmanship ensure you'll enjoy great sound.
Assembled and inspected by hand
Focal assembles its subs by hand in their French facilities and rigorously inspects each one for any flaws to ensure your investment performs to the highest sonic standards. Mount this 4-ohm sub in a sealed enclosure to produce bass that's highly accurate and plenty forceful, then feed it up to 350 watts RMS without fear.
A powerful magnet drives the sound
A neodymium magnet supplies the backbone for the sub's powerful output, driving the motor assembly with unerring precision. Focal anchors the K2 Power sub with an aluminum basket that combines rigidity and efficient heat dissipation for reduced distortion and longer speaker life.
4-layer cone delivers sonic fidelity
Focal's proprietary K2 4-layer aramid fiber composite sandwich cone combines rigidity and responsiveness to deliver sonic fidelity and high power handling. A butyl rubber surround maintains control of the cone, even during deep excursion.
