Add dedicated height channels to your Polk Signature or Signature Elite speakers with the brown Signature Elite ES90 Height Module Speakers from Polk Audio. For detailed sound and imaging, the ES90s feature a 1″ Terylene dome tweeter and a 5.25″ mica-fortified polypropylene woofer. They utilize an up-firing design to provide immersive overhead sound. These speakers are voiced and designed for use with specific Polk Audio speakers. They have a molded rubber base designed to sit perfectly atop the Signature Elite Series ES55, ES60, and ES20 or the Signature Series S20, S55, and S60 speakers.

Note:

The ES90 is not compatible with ES50 or S50 tower speakers or ES15 or S15 bookshelf speakers.
Extra-Large Woofer
The 5.25″ mica-fortified polypropylene midrange woofers offer 75 percent more surface area than traditional 4″ height speaker drivers, filling even large rooms with full-range, impactful, enveloping sound.
Terylene Dome Tweeter
The premium 1″ Terylene dome tweeters present crystal clear, detailed highs for precise imaging and consistent sound with Signature Elite or original Signature Series speakers.
Secure Fit
A molded rubber base securely isolates each height module atop its companion speaker, preventing unwanted artifacts like rattles and buzzes.
