What customers say
Customers consistently praise the Polk Audio Reserve R900 Height Module for its exceptional sound quality, delivering an immersive audio experience that significantly enhances home theater setups. Many highlight how seamlessly these modules integrate with other Polk Reserve speakers, both aesthetically and acoustically.

Know before you buy
While the R900s are timbre-matched to the Reserve Series for a seamless soundstage, they are technically compatible with any home theater system that supports Dolby Atmos or DTS:X. However, for the most consistent audio performance, we recommend pairing them with other speakers from the Polk Reserve line.
Placement depends on your room layout and ceiling height. Placing them atop your existing speakers uses sound reflection to create height effects, while wall mounting allows you to direct the sound more precisely toward your listening position, which is often preferred for dedicated home theater setups.
The R900s are compatible with standard amplifiers ranging from 4Ω to 8Ω and perform best with a power output between 45W and 100W per channel. Ensure your AV receiver supports the height channels required for Dolby Atmos or DTS:X to get the full benefit of these modules.
The Pinnacle Ring Radiator Tweeter is designed to provide ultra-clear high-frequency response without unwanted coloration or distortion. It creates a wider 'sweet spot,' ensuring that the immersive height effects are audible and detailed from multiple seating positions in your room.
While they are primarily designed to add height channels for cinematic formats like Dolby Atmos and IMAX Enhanced, they also enhance music playback. When using upmixing modes on your receiver, these modules help create a more expansive, three-dimensional soundstage for your favorite tracks.
