About the Focal Sub 10

Bob Bihlmayer

Solid performance

Focal has long been renowned for the quality of their speakers, and our customers agree — they consistently give their subs excellent ratings. Their Sub 10 subwoofer continues the tradition with solid, clean bass, even at high volume levels. The sub's 4-ohm impedance makes it a great match for most amplifiers.

Built to take it

The Sub 10's polypropylene cone and butyl rubber surround handle up to 250 watts RMS with ease, with a vented steel basket that helps dissipate heat buildup when things are running hot. This sub's versatility fits into just about any kind of system, whether you prefer tight bass from a sealed box or fatter bass from a ported enclosure. You can add stylish protection to your sub with Focal's specially-designed 10" grille (sold separately).

Product Research

Features

Materials: Focal uses a polypropylene cone and butyl rubber surround to withstand the harsh automotive environment.

Spring-Posts: The sub has spring-post terminals for easy connection of single banana plugs, pin connectors, or bare wire up to 10 gauge.

Sealed Enclosures: Sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable for all types of music. Focal lists four sealed enclosure examples in the manual:

  • 10 liters/0.35 ft³, resulting in a -3 dB point of 37 Hz
  • 15 liters/0.53 ft³, resulting in a -3 dB point of 33 Hz
  • 20 liters/0.71 ft³, resulting in a -3 dB point of 31 Hz
  • 25 liters/0.88 ft³, resulting in a -3 dB point of 30 Hz

Ported Enclosures: Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier. Focal lists three ported enclosure examples in the manual:

  • 25 liters/0.88 ft³ using a 7cm/2.75" diameter x 35cm/13.75" long port, resulting in a tuning frequency of 35 Hz
  • 30 liters/1.06 ft³ using an 8cm/3.15" diameter x 45cm/17.72" long port, resulting in a tuning frequency of 31 Hz
  • 35 liters/1.24 ft³ using an 8cm/3.15" diameter x 45cm/17.72" long port, resulting in a tuning frequency of 28 Hz
