12" Monoprice SW-12 400W RMS Powered Subwoofer Speaker (Black)

12in Driver: Size does matter. The heavy duty, long throw, front firing driver has been engineered to produce gobs of impactful deep bass and can pressurize larger spaces. This ensures you are hearing and feeling bass on every music track or your favorite movie.
Powerful Amplifier: 400 Watts of Class D Power. Complete control. Use the easy access, rear panel controls to tune the bass to your preferences. The volume control and low pass filter allow you to blend the bass from the subwoofer into the sound from your main speakers. The phase control can compensate for subwoofer positioning and the power mode turns auto standby on or off.
Simple Hook-Up: Plug and Play. Use the RCA inputs to connect to a dedicated subwoofer output or to preamp outputs on your amp or use the speaker level inputs to connect to the speaker outputs, if your amp lacks subwoofer or preamp outputs.
Ported design.
33 ~ 150Hz frequency response.
