About the Sony XS-GSW121

Advanced materials

Sony created their GS Series subwoofers with performance in mind. Their XS-GS121 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.

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-121 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 want more bass in your space, Sony's ready to back you up. 

To drive this single subwoofer, we recommend a mono amplifier rated between 375 and 750 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Great Sub!!

Brian from Indianapolis, IN on 4/26/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

I've been looking at more expensive subs but every time I'm in my Jeep listening to music, I can't help but love the sound this sub produces. Been running it almost a year with zero issues. Like it so much I'm doubling up!

Pros: Powerful, clean bass.

Cons: I haven't found any yet.

Product Research

Features

Cone: The xs-GSW121 uses a honeycomb design MRC cone (Mica Reinforced Cellular glass fiber composite) to reduce weight and increase rigidity, delivering deep bass response.

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-GSW121 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 11-1/8" long port.

Specification Note: Sony's rated power spec for the xs-GSW121 is 400 watts (derived using IEC 60268-5 standards). In the manual they also list the CEA 2031 compliant RMS power as 500 watts. We've adopted the 500 watt RMS rating because CEA 2031 is the more common rating system.

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).

Q
Does anyone own this sub? I cant find that many customer reviews on it yet I'm not sure if it's because it's a new sub or what, I also thought about getting the Sony XM-GS100 Amp, What Sony Amp if Not this one do you suggest getting to go in a Stock 2K14 Camaro? Thanks for your help.
