Real presence

Focal engineers applied some of their most innovative technologies, including an M-profile Aramid fiber cone, to make this tidy 5" sub uniquely equipped for maximum output, despite its small size. The shape and material help reduce harmonic distortion so you'll enjoy Focal's signature clean, unstressed, K2 sound.

Focal also prioritizes shallow depth to make this special speaker a better fit for more installation locations. And with power handling up to 200 watts RMS, you can safely drive this sub with a healthy amount of power.

This component sub was designed to be part of a Focal K2 Power M system, incorporating these other high-performance speakers:

These components will deliver the ultimate in car audio performance, whether you install them in factory speaker locations or use them for a custom installation.

Product Research

Features

Enclosure: Focal recommends a sealed enclosure for the SUB 5 KM; sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable for all types of music. Focal lists two sealed enclosure examples in the manual; performance is best in an enclosure between these volumes:

  • 4 liters/0.141 ft³, resulting in a -3 dB point of 41 Hz
  • 6 liters/0.212 ft³, resulting in a -3 dB point of 39 Hz

Crossover: The K2 Power M series components are designed to be actively crossed over, and no crossovers are included. A subsonic filter is recommended at 30 Hz, and a low pass crossover between 70 and 100 Hz.

Q
Does this sub come with a template?

A
There is no template included with the Focal SUB5KM K2 Power M series 5 3/4" subwoofer, Brook. The speaker requires a hole cutout of 5 3/16".

Q
How can I test a used sub-woofer before buying to ensure that it works correctly?

Greetings Michael. We are in the market of selling new equipment. Testing to see if an old subwoofer is still in working order would be assisted by technical support. Perhaps contact the manufacture of the subwoofer. Or connect it to a working amplifier.
