Klipsch R-121SW 12" Subwoofer vs Monoprice 12-Inch Powered Subwoofer

The Klipsch R-121SW is the stronger pick for most people. It has more RMS power, a braced 3/4-inch MDF cabinet, phase control and wireless capability, and it scores higher with owners. The Monoprice is a solid budget alternative with a wider frequency range, a fully adjustable crossover and speaker-level inputs, but its lighter build and lower power show in a less controlled low end.

• Choose the Klipsch R-121SW if you want more output, a sturdier cabinet and phase control for blending with a home theater system.
• Choose the Monoprice 12-inch if you need speaker-level inputs for an older stereo receiver or want a crossover that adjusts across the full range.
