Five sides equals big bass
The design of the Sony's GTR Series XS-GTR121L 12" 4-ohm subwoofer not only catches your eye, but it also helps give you better bass. The five-sided woofer cone reduces standing waves, which can diminish the bass output. The unique "dimple" design makes the cone more rigid so it'll hold its shape at high output levels, and it reduces the cone's weight so it's more responsive. You'll enjoy tight, accurate bass.
This XS-GTR121L handles up to 400 watts RMS, impressive for a sub in this price range. Even though the cone has five sides, this Sony still fits in a standard round opening in either a ported or sealed enclosure.
To drive this single subwoofer, we recommend a mono amplifier rated between 300 and 600 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
