Are these original speakers?

No, there were speakers long before these existed.

Does it need to be plugged in at all times?

These speakers require speaker wire to be connected to them when being listened to. There is no power cable to be plugged in.

Is this a single speaker or a pair of speakers?

Since this question was asked regarding the Atrium 8 version but Amazon shows it under both the 6 and 8 version, the Atrium 8 version is sold as a single speaker. The Atrium 6 version (and smaller) are sold as pairs.

What is the rms wattage per speaker? I cannot get a straight answer!

Polk claims they will handle up to 125 watts per channel, but with a sensitivity of 91dB 《8 ohm) these speakers get very loud quickly. I have an older Technics H class receiver (100 watts p/ch) & have never pushed over half volume on my pair. Note: I do enjoy cranking it up. With a freq. response of 45 - 27,000Hz, I found a sub wasn't needed. Placement, area & environment ( walls, height, corner availability) make a big difference when installing them correctly, but wattage shouldn't be a concern. These speakers are a great buy for the price.
