## Questions & Answers

**Q: Are these original speakers?**
A: No, there were speakers long before these existed.

**Q: Does it need to be plugged in at all times?**
A: These speakers require speaker wire to be connected to them when being listened to. There is no power cable to be plugged in.

**Q: Is this a single speaker or a pair of speakers?**
A: 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.

**Q: What is the rms wattage per speaker? I cannot get a straight answer!**
A: 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.

Déçue … ce n’est pas un lot de deux comme indiqué dans la description mais une seule enceinte j’ai choisi la blanche j’ai reçu une noire … je l’ai renvoyé sans l’utiliser. Trop d’erreur dans le descriptif pour ce prix là.
