## 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.

### ⭐⭐⭐⭐⭐ Review
*by R***I on 8 April 2018*

POLK Atrium 8 SDI , das ist ein Stereo Lautsprecher der als Stereo oder Singel zu betreiben ist. Habe mir direkt 2 Stück geordert, klanglich für so ein Kunststoffgehäuse einfach Top. Ich hatte mir erst die Bose 251 ausgesucht, preislich auf gleichem Nivau, da dort aber immer gemischte Bewertungen auftauchen, habe ich mich für Polk entschieden. Hier liest man aber nur sehr wenig drüber, da wohl zu selten in Deutschland. Als vergleich habe ich mir dann noch die Jamo I/O 8 A2 dazu bestellt. Sind dann direkt 1 Paar. Preis 379€ Diese haben sogar 8 Zoll, sprich 20cm Bass Mittelton und ich hatte mir dort etwas mehr Bass erwartet. Jamo gibt aber weniger an, ab 50Hz, Polk mit 6,5 Zoll sogar schon ab 45Hz. Jamo hat Bassreflex Öffnung vorne, Polk hat hinten eine Bassport, bei diesen kann man dann bei Eckmontagen den Bassefekt noch verstärken. Also schnell noch die Jamo geordert zum Vergleich, wären ja als Paar auch noch günstiger als die Polk. Angeschlossen und somit hatte ich einen direkten vergleich zu den Polk. Die Jamo sind auch nicht schlecht, gehen aber wirklich nicht tiefer runter wie die Polk, was aus dem Datenbaltt ja auch zu sehen war. Die Jamo haben einen sehr dominanten Mittelton und lösen nicht so fein auf wie die Polk. Ich hatte die Polk für 245€ das Stück bekommen hier auf Amazon, zusammnen also 490€. Diese 110€ mehr zu Jamo sind es mir auf jeden fall wert. Mit nur einem Polk Atrium 8 SDI im Stereo Modus wäre ich aber auch nicht glücklich geworden, mit 2 Stück, diese hängen ca 4m auseinander und strahlen im 45 Gradwinkel nach unten passt es aber super, sehr feine höhen und auch bei leiser Lautstärke ein sehr homogenes Klangbild. Überdacht mit Terrassen Glasdach 10mm mit 28m² ,betrieben werden diese an einem DENON X4000 an Zone 2. Zur Farbe, ich habe weiß genommen bei beiden, Jamo sowohl Polk sind nicht reinweiß, eher Richtung beige / grau. Stört aber nicht da meine Ausenwand gelblich ist und das Terrassendach silbergrau, passt sehr gut dazu. Beide sind aber auch in Wunschfarbe lackierbar, wie in deren Anleitungen auch beschrieben ist. Fazit Die Jamo sind auch nicht schlecht, aber mir persöhnlich gefallen die Polk klangtechnich wesentlich besser. Ist natürlich alles geschmackssache und eine Preisfrage. Die befestigung ist bei den Polk sehr einfach, Halter festschrauben, Lautsprecher einklicken, Ausrichten und festdrehen, fertig. Das Ausrichten geht jedoch, wenn der Halter einmal Positioniert ist, nur noch seitlich oder vertikal wenn der Halter quer verschraubt wird. Die Jamo sind beim montieren etwas aufwendiger, können jedoch anschließend noch in beider Richtungen verstellt werden. Beide sind im Bassbereich natürlich nicht mit ausgewachsenen Lautsprechern zu vergleichen, wer Außen richtig druck haben will, muss zusätzlich noch ein SUB installieren, dort gibt es ja nun auch einige für den Outdoorbereich.
