Our take on the Sony XS-GSW121D

by Bob Bihlmayer
Sony

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.

Advanced materials

Sony XM-GS100 330W x 1 Subwoofer Amplifier

Sony created their GS Series subwoofers with performance in mind. The Sony XS-GS121D 12" subwoofer features a unique mica-reinforced cellular glass fiber material that's foamed in a honeycomb fiber base, making it 10 times more rigid than a polypropylene cone. Sony formulated a surface layer for the cone that's made up of mica flake, synthetic fiber, and pulp. creating an extremely light and rigid cone that's able to move faster and more accurately. You'll hear greater precision and lower distortion, and the dual 4-ohm voice coils allow this speaker to run at 2 ohms for even greater firepower.

Serious power handling for this price range

A rugged rubber surround helps this Sony sub handle up to 500 watts RMS, while a double-layered spider supports the voice coil for a 55% increase in cone travel over last year's model. The GS-121D is equally at home in a ported or sealed enclosure, so you can choose the sound you want for your system. And best of all, Sony backs up these workhorse subs with a cool 3-year warranty. If you've got the room, Sony's got the boom.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Cone: The xs-GSW121D uses a honeycomb design MRC cone (Mica Reinforced Cellular glass fiber composite) to reduce weight and increase rigidity, delivering deep bass response.

Dual Voice Coils: For increased system flexibility, the woofer has two 4Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 2Ω load. When the voice coils are wired in series, the woofer presents an 8Ω load.

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 close together to accept dual banana plugs.

Enclosure Compatibility: The xs-GSW121D is compatible with either a sealed or ported enclosure.

  • Sealed Box Volume: The ideal sealed box volume is 0.84 ft³.
  • Ported Box Volume: The ideal ported box volume is 1.37 ft³ with a 4" diameter and 11-7/8" long port.

Specification Note: Sony's rated power spec for the xs-GSW121D is 420 watts (derived using IEC 60268-5 standards). They also list the CEA 2031 compliant RMS power as 520 watts. We've adopted the 420 watt rating simply because it's the more conservative figure.

Trim Ring: If the sub is mounted without the cosmetic trim ring, the flange height is 0.241" and the mounting height is 0.6" (top mount).
