Polk Audio Signature Elite ES90 Height Module

These modules are designed to sit on top of your existing floor-standing or bookshelf speakers. They fire sound upward toward your ceiling, which then reflects the audio back down to your listening position, simulating the overhead effects required for formats like Dolby Atmos.

While they are timbre-matched to the Signature Elite series for the most cohesive soundstage, they can be used with other speaker brands. However, you may notice slight differences in sonic character if your main speakers have a significantly different tweeter or driver design.

These modules perform best with flat, hard, and reflective ceilings, such as drywall or plaster. Vaulted, beamed, or acoustic-tiled ceilings can scatter the sound waves, which may reduce the effectiveness of the immersive overhead effect.

Yes, the ES90 modules feature integrated keyhole slots on the back, allowing you to mount them directly to the wall. This is a great alternative if your current speakers have a curved top or if you prefer a cleaner look.

The ES90s are rated for 20–150W per channel with a 4-ohm impedance. Most modern home theater receivers can handle this load, but you should verify that your receiver supports a 4-ohm speaker configuration in its settings menu to ensure optimal performance and safety.

No, the package includes 50 feet of high-quality oxygen-free copper speaker wire. This should be plenty to connect the modules to your receiver, assuming your receiver is located within a standard distance from your main speaker setup.
