Extraordinary bass response

PowerPort® Bass Venting

You’ll experience space-filling sound in any outdoor area, porch, sunroom, or deck. Polk’s patented water-resistant PowerPort® efficiently adds 3dB of big, realistic, musical bass output. And when combined with its anodized aluminum tweeter domes, this speaker not only delivers powerful, high-quality sound output, but excellent midrange clarity.

Great outdoor sound

Whether you’re lounging in your favorite chair, hosting a BBQ, or spending time with the family outdoors, you won’t miss a single word of your favorite tunes. The Atrium Series outdoor speakers deliver crisp, powerful vocals—without distortion. Their Patented Dynamic Balance® and Klippel Optimization Technologies ensure optimal material performance, eliminating driver and tweeter “artifacts” for more realistic sound reproduction at high and low volume levels.

Questions

Speaker(1)  to replace dual speakers, 250 ft one open side patio, med to medium low volume. Is this speaker good as stereo single, is power level ok for space, and wired with existing wire that is functioning to a speaker, about same size.

Asked by: Gpdsr

Yes, the Polk Audio Atrium 8 SDI is an outdoor speaker that can be used as a Left and Right stereo speaker (single) or as a stereo pair when adding a second. The Atrium 8 SDI excepts standard speaker wire. A second speaker can be added depending on the coverage and volume desired.

I am looking at replacing my current outdoor speakers. I have a 4 speaker Bose setup atm. Front and rear speakers are around 10 mtrs apart. Should I get 2 or 4 Polk atrium 8 speakers?

Asked by: PaulieW

If you are currently wired for four outdoor speakers, I recommend 4 Atrium 8 speakers considering the distance and being outdoors.

I'm looking for quality ceiling mounted ATMOS speakers for dedicated home theater (not in-ceiling). Will these speakers perform well indoors with good even freq. range as ATMOS speakers?

Asked by: mrchuck

Yes, Atrium speakers can be used in this situation. An atrium 6 speaker may also be used. Using the Atrium 8, I recommend using the speaker as a single speaker and not a stereo speaker.

If U had a pair can U hook up 4 different channels from a surround avr, 2 lefts to 1 and 2 rights to the other? Also how would that sound?

Asked by: WOLFBEING

This type of application is not recommended. The Atrium 8 SDI has two tweeters but one midbass driver. This works in a stereo configuration, but not a discreet configuration recommended in a surround sound system.

Wondering about using this speaker indoors, to fill a small-medium room, set up as as single stereo loudspeaker? Or might you have a recommendation for a similar dual/single speaker setup with an indoor speaker?

Asked by: tbaker26

Hello, the Polk Audio Atrium 8 SDI speaker will perform well in this situation. For a stealthier installation, consider our V6S in-ceiling stereo speaker. https://www.polkaudio.com/en-us/product/in-wall-in-ceiling-speakers/v6s

Can they both be use for l/r speakers in home stereo system ?

Asked by: Gojojo

If you buy 2 of these speakers you can use them two different ways. 1. As  A stereo setup one left and the other a right speaker. 2. As two separate zones of left and right thru each speaker as long as your amplifier has 2 sets of left and right speaker outputs ( or alternative wiring such as parallel or series wiring depending on the resistance load your receiver/ amplifier can handle.
