Because Upstream is More Fun Than Mainstream

The EX572a features:

  • Liquid Crystal Polymer driver cones for better performance and reliability
  • Butyl rubber surrounds for better performance and greater reliability
  • Ferro-magnetic fluid cooled tweeters for high SPL
  • Low profile design to ensure a perfect fit in a wide variety of locations

EX Series II full range and coaxial speakers are an ideal combination of high performance and "drop-in" flexibility. Designed to replace your factory speakers, they are exactingly engineered with high quality materials to provide state-of-the-art performance without the hassle of custom installation. That's 'cause Polk designed the EX Series II with multi-hole mounting patterns and extremely low profiles to ensure an easy fit into virtually any factory speaker location.

Speakers have to fit into your car, huh? Extensive database research helped us develop a multi-hole drop-in system to fit virtually every application. From a Miata to a Firebird to a Jeep Wrangler, there's an EX Series II speaker that drops right into your car. No cutting. No knuckle banging. No hassle. We are ALL ABOUT database research here at Polk Audio.

EXII speakers use materials that are usually found only in speakers costing much more. The butyl rubber surrounds help give them smooth midrange and extended bass response, and won't tear or crack like foam rubber surrounds found in other brands. The polymer composite cones in the midranges and woofers are moisture resistant and light -- yet extremely rigid for lightning quick response with extremely low distortion.

The Polk EX Series: They're everything you need in a car speaker. Incredible sound at an affordable price. Designed to fit. And built to last.
