Sony's Slim Series subwoofers dish out powerful low-frequency performance, and their compact profile enables you to add bass to the tight confines of smaller vehicles. Find a suitable box or build a custom enclosure to fit your needs, and let Sony's advanced technology turn those areas behind or under your seats into premium bass outposts.

The XS-L12S 12" subwoofer incorporates the superior rigidity of polypropylene into its unique five-sided cone. The pentagonal design also helps reduce standing waves found in round subwoofers, eliminating potential distortion which can harm your bass output. A tough rubber surround allows the sub to take a pounding and stay under control.

No worries about power — the XS-L12S can handle 380 watts RMS without fear of a meltdown. Gold-plated, 5-way binding posts offer a convenient, super-efficient connection to your amplifier.

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.

Small price for a small sub

Written By Geoff, Arizona on Saturday, April 11, 2009

Crutchfield Customer Review (What's this?)

I have this sub in a 14X14X4 inch mdf sealed box. I wanted something nice and compact and it has a nice hit in the higher volume levels. By any means is this a competition speaker, it will just add some kick to your music without taking up a lot of room.

Product Research



Shallow Mount Woofer: Sony's Slim Series subwoofers are designed to provide wider installation options for a broad range of vehicles. They can be mounted behind or under the seats of many vehicles where full size woofers won't fit.

P5 Cone: This woofer has a five-sided polypropylene one-piece, cap-less cone. The unique Turbo cone design stiffens the cone and increases rigidity, resulting in lower distortion and higher power handling. The five-sided cone also cuts down on standing waves on its surface because none of the five sides is parallel to another.

Stroke Stabilizer Rubber Surround: The rubber surround provides enhanced cone control and flexibility, as well as durability. Hash Marks in the surround provide added stability.

Binding Posts: The gold-plated binding posts will accept bare wire up to 10 Gauge, pin connectors, spade lugs and banana plugs. The binding posts are spaced too far apart to accept dual banana plugs.


Sealed Box Volume: Sony recommends mounting this woofer in a sealed enclosure with an internal volume of 0.95 cu/ft.

Ported Box Volume: Below the Thiele/Small parameter chart on the spec sheet Sony recommends mounting this woofer in a sealed enclosure, but in the box dimension section they list a ported enclosure with an internal volume of 1.20 cu/ft and one 3" diameter x 10.875" long port.
