Matrix M10.1 10

Hand-built woofer cone

The Matrix M10.1 10" subwoofer gives you phenomenal low-frequency reproduction that'll augment your full-range speakers perfectly. Brax builds this speaker's cone by hand, using Agave sisalana fibers mixed with aluminum oxide to make a driver that's lightweight and rigid, as well as exceptionally accurate. They anchor this cone to the specially designed die-cast aluminum basket with a heavy-duty rubber surround for maximum stability. Extra venting at both the spider and pole piece keeps this sub running cool. You can turn up the volume without worrying about unwanted distortion.

Quality and quantity

Speaking of turning it up, this sub's handwound voice coil and double-stacked magnets help it to handle up to 600 watts RMS, so you can have your bass cake and eat it too. You no longer have to sacrifice loudness for sound quality or vice-versa, as this sub will give you incredibly detailed lows and play cleanly at very high levels. For best results, mount this sub in a sealed or ported enclosure.

To drive this single subwoofer, we recommend a mono amplifier rated between 450 and 900 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Product Research


Cone Design: The subwoofer's Agave Sisalana fibers are infused with aluminum oxide, resulting in a lightweight and rigid driver to produce quick, accurate, well rounded bass response. The M10.1 also uses a durable rubber surround.

Motor Structure: The hand wound voice coil is energized by double stacked magnets and cooled by pole piece and spider plateau venting.

Terminals: The spring post terminals accept pin connectors, single or dual banana plugs, or bare wire up to 8-gauge.

Cast Aluminum Basket: The die-cast aluminum basket resists flexing and resonance (ringing).


  • Sealed: Brax recommends a 1.0 cubic foot sealed box for the M10.1.
  • Ported Enclosure: Brax recommends a 1.5 cubic foot ported enclosure with a 4" diameter port tube. Two port length options are recommended, 18.75" (resulting in 35 Hz tuning frequency and 33.5 Hz -3dB frequency) or 13.5" (resulting in 40 Hz tuning frequency and 35 Hz -3dB frequency).
