Sony designed their Xplōd™ GTR subs with a unique design that delivers impactful, chest-thumping low notes. The Sony XS-GTR120L 12" sub features an innovative five-sided polymer cone that reduces standing waves that can diminish your bass output. Dimples in the cone serve a dual purpose — they reinforce the cone for optimal stiffness, and lighten it for quick response between notes.

This sub handles up to 380 watts RMS, and its steadfast rubber surround and sturdy internal construction gives you strong performance over the long haul. The woofer installs in a standard round opening, and works well in sealed or ported enclosures.

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.

Overall, this subwoofer is a good value. The sound is nice and deep. I bought this speaker to replace a blown Sony Xplod XS-GTX120LW. I was hoping for better sound, but the quality is disappointingly similar. The cone has a cool design and looks nice. Unfortunately the back of the subwoofer is cheap plastic and not metal like it appears in the photos. I am considering to buy a second one of these and purchasing a double box because this subwoofer is too small for my Kenwood 7205 500 watt rms amp. I would recommend this product to a friend, but I am disappointed by the plastic rear of the subwoofer. Overall, you can not beat this subwoofer's combination of price and sound.

Pros: Price,Cool looking woofer cone, good sound

Cons: Plastic shield.

Great sound, great price.

P5 Cone Design: The five-sided polypropylene cone uses a unique dimpled design; this stiffens the cone, resulting in lower distortion and higher power handling.

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.
