Know before you buy
These modules are compatible with any receiver that supports 4 or 8-ohm loads. However, to experience the intended Dolby Atmos, DTS:X, or IMAX Enhanced overhead effects, your receiver must be capable of processing those specific surround sound formats.
While these modules are designed to sit perfectly atop Polk Signature Elite speakers, they can technically be placed on any flat-topped speaker. Keep in mind that they are timbre-matched to the Signature Elite series, so you may notice a slight difference in sound character if paired with other brands.
These speakers are designed to sit on top of your existing floor-standing or bookshelf speakers. They fire sound upward toward the ceiling, which then reflects the audio back down to your listening position, simulating the effect of overhead speakers.
They are specifically designed to mount securely on the ES20, ES55, and ES60 models. Their base is molded to fit the dimensions and aesthetic of these specific speakers for a stable, seamless integration.
Yes, each height module requires its own dedicated speaker wire connection to your receiver's height or 'presence' channel terminals. They do not draw power or signal from the main speaker they are sitting on.
