No, it plugs into the wall, both the base and main speakers. Go to the Polk website and watch their video.

It is all powered, no need for an amplifier. It works well and sounds great!

This speaker is a powered speaker, meaning that it has a built-in amp. It does require power either from the wall, or car converter, or battery pack (car battery size)

No......it needs a amp to power it. Such as a surround sound receiver or stereo system.

Active. You do NOT need an amplifier. The amplifier is built into the speakers and each speaker needs power and each comes with its own power cord I love the clean sound and works well for near field monitoring. I am NOT a professional in music.

The amplifier comes with a usb cable, if your tv has a usb port it can get power from that, otherwise it comes with an ac adapter for power. You definitely need the amp plugged in and hooked up though if you want to get all the channels it can. In some areas, close to the transmit towers you may pick up some stations without the amp, but usually you will have to have it hooked up to get clear reception.

It is bus powered, but also includes a power supply, so you have the option.-Pro Audio Land

It's battery powered. And it works great especially when playing recorded C.D.'s. Which was why I got one.

It came with a power supply and you can directly connect to your amplifier.

Hello there , no built in amp. Must use reciver or pre-amp for hook /up. I use a 500 watt app, you don't need much power. Great sound no need to blow your ear/drums out.

That depends on what you use it for. If it's your new end table, or dinning room center piece, then the answer is no. Now if you use it as a speaker for listening to music and such, then yes, some sort of powered amp will be necessary. Otherwise it would have a hole in the rear for you to sing, talk, or make noise through.

Yeah! So I've plugged mine in for a power source, but it takes batteries.However, it doesn't have a speaker/amp so you'd need to orchestrate a way to do that

You can run a subwoofer off this amp. I'm not sure what you mean by powered subwoofer

It is NOT powered but there is a powered model available. My only problem with a powered speaker is that if the internal amp is broken, the speaker is unusable and can NOT be equalized like an external amp with an electric equalizer.

HI, it's powered itself. you just need to buy the set of wires to connect it to the stereo.

No. You either need to output to powered speakers, or feed this pre-amp into a power amplifier (that in turn will drive unpowered speakers). This is just a mixer and pre-amp. (And a fine one for the money, IMO. I've been very happy with my purchase.)
