Klipsch Subwoofer



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.

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.
