Overview
The Klipsch SUB 100 is a floor-standing subwoofer with an 80 watt amplifier driving a 10-inch driver, finished in ebony and weighing about 28 pounds.
A 10-inch driver in a cabinet sized around 13.75 by 13.19 by 13.38 inches is a compromise between low-frequency output and a footprint that fits under a TV stand or beside a rack, rather than a large 12-inch or 15-inch tower built for maximum bass. The USB connectivity here most likely serves setup or firmware functions rather than audio input, since subwoofers typically take a low-frequency line-in rather than digital audio over USB.

Who it's for
Fits a room-scale system needing added low end from movies or music without a large-footprint subwoofer cabinet. Not for a home theater built around maximum output in a large room, where a bigger driver would do more.
Strengths and trade-offs
Drawn from this product's published specifications.
- 10-inch driver with 80 watts of power
- Compact cabinet fits smaller rooms easily
- Floor-standing design needs no shelf or stand
- 80 watts and 10-inch driver trail larger subwoofers
- USB port is likely for setup, not audio input
Performance notes
An 80 watt amplifier paired with a 10-inch driver is a mid-range combination for a subwoofer, enough to add low-frequency weight to movie soundtracks and music in an average-size room without the output ceiling of larger 12-inch or 15-inch designs. The floor-standing cabinet at 28 lb is stable enough to sit on its own rather than needing a shelf.
