This is a 15 inch powered sub woofer with an on board amplifier rated at 200 watts with a frequency response of 200hz to 20hz. It has a high frequency cut off from 200hz to 20hz. Phase selection can be normal or reverse. The automatic cutoff frequency feature is very important. For my use I decided a cutoff frequency of about 100hz is just right. A few years ago, you would have had to purchase an electronic cutoff in addition to the sub woofer since it is included it saves both money and headaches. Another wonderful feature of this sub woofer is its level (volume) control. Experimentation demonstrated a level of about 33% rendered strong, very low base without employing ear damaging volume. This sub woofer is magnetically shielded to prevent television distortion. The instructions are excellent. The warranty is competitive. The only down side is the supplied connection wire, it is only 6 feet long. In my circumstance, testing demonstrated speaker placement was best in a corner on the room. This compeller me to spend $19 on a 12 Foot connection wire.
