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.
To drive this single subwoofer, we recommend a mono amplifier rated between 375 and 750 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
