Unique woofer shape
Sony created their GS Series subwoofers with performance in mind. The Sony XS-GS120L 12" subwoofer features a unique five-sided cone that reduces standing waves that can diminish bass output. Sony use a mica-reinforced cellular glass fiber material to create an extremely light and rigid cone that's able to move faster and more accurately — you'll feel every low note.

Built to last (and rock)
This sub will handle up to 380 watts RMS, and a rugged rubber surround helps this Sony handle big power for a long, long time. Despite its unique design, this sub fits into a standard round cutout, plus it's equally at home in a ported or sealed enclosure. And best of all, Sony backs up these workhorse subs with a cool 3-year warranty.

To drive this single subwoofer, we recommend a mono amplifier rated between 285 and 570 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.

P5 Cone Design: The five-sided XS-GS120L uses an MRC cone (Mica Reinforced Cellular glass fiber composite) to reduce weight and increase rigidity, delivering deep bass response.

Rubber Surround: The Hash Marks on the rubber Stroke Stabilizer surround provide added stability.

Binding Posts: The binding post wire terminals will accept pin connectors, spade lugs, single banana plugs, and bare wire up to 10 gauge. The binding posts are spaced too far apart to accept dual banana plugs.

Enclosure Compatibility: This woofer can provide extended bass in sealed and ported enclosures:

  • Sealed Enclosure Volume: 0.77 cubic feet
  • Ported Enclosure Volume: 1.13 cubic feet using one 3" diameter x 11-3/4" long port

Specification Note: Sony's rated power spec for the XS-GS120L is 380 watts (derived using IEC 60268-5 standards). They also list the CEA 2031 compliant RMS power as 500 watts. We've adopted the 380 watt rating simply because it's the more conservative figure.
