  • Adding a Subwoofer to Your Home Theater



The SW-450 subwoofer uncovers what you've been missing in your music movies and video games -- clean chest-thumping bass. It's an ideal companion for many of our front, center, and surround speakers, whether you're looking to achieve a 5.1 system or a 5.1 on the Richter scale.

  • Powerful 10-inch driver offers increased bass response with low distortion
  • Built-in Class D amplifier delivers 450 booming watts of dynamic power
  • Sleek modern design complements today's HDTVs
  • Works perfectly with many speakers in the Klipsch line

Great sound begins with a great bottom end. The SW-450 subwoofer delivers the two lowest octaves of the ten humans can hear intensifying your listening and viewing experiences.

The SW-450 fills any room with big clear bass thanks to its powerful 10-inch driver and Class D amplifier. But if you really want to experience what this hard-hitter can do be sure to place it in the corner of your room. In general placing a subwoofer along the middle of the wall or out in the room will decrease its output.

In addition to its unparalleled performance the SW-450 offers unmatched flexibility. A low pass crossover and variable phase control lets you effectively blend the subwoofer’s low-frequency tones with other Klipsch speakers as well as establish a level of bass that’s just right for your room.

The SW-450 subwoofer is truly the way to go if you want to hear—and feel—your stereo or home theater entertainment.
