Polk Audio Reserve R900 Height Module

Yes, the R900 modules are designed to be versatile. While they are timbre-matched to the Reserve series for a seamless soundstage, they can be used with any high-quality speaker system to add height channels.

No, that is the main advantage of these modules. You can place them on top of your existing floor-standing speakers to bounce sound off the ceiling, or mount them directly to the wall, avoiding the need for complex ceiling installations.

Placing them on top of speakers uses 'up-firing' technology to bounce sound off the ceiling, creating an immersive overhead effect. Wall-mounting allows you to direct the sound more precisely toward your listening position, which is often preferred for specific room layouts.

The R900s are compatible with most modern AV receivers that support Dolby Atmos and DTS:X. Just ensure your receiver has the necessary channels to power these height modules, and check that your amplifier can handle a 4.2-ohm minimum impedance.

We recommend an amplifier with a power output between 45 and 100 watts per channel. This range ensures the drivers perform optimally without distortion.

If you are using the up-firing configuration (placing them on top of speakers), vaulted or extremely high ceilings can diffuse the sound too much, reducing the effectiveness of the height effect. In those cases, wall-mounting the modules is a much more reliable way to achieve the intended surround sound experience.
