About the Polk EX357

Polk designed the EX3 Series to deliver audiophile performance, whether they're powered by an in-dash receiver (even a "factory" model) or by an external amp. The EX357 5"x7"/6"x8" speaker pumps out impressive bass from a moisture-resistant mica-filled polymer composite woofer with a durable butyl rubber surround.

Polk designed the EX3 Series to deliver audiophile performance, whether they're powered by an in-dash receiver (even a "factory" model) or by an external amp. The EX357 5"x7"/6"x8" speaker pumps out impressive bass from a moisture-resistant mica-filled polymer composite woofer with a durable butyl rubber surround.

A 3/4" soft dome tweeter broadcasts smooth, detailed highs, while the REL (Rotating Elliptical Lens) improves imaging, even from less-than-ideal factory speaker locations. Grilles are not included. (Factory grilles are appropriate for most installations.) 1-year warranty.

Product Research

Features

Woofers: The moisture-resistant mica-filled polymer composite woofer cones produce full, accurate midbass, while the durable butyl rubber surrounds increase speaker life and improve bass response.

Tweeters: Each speaker uses a 3/4" silk dome tweeter for smooth, accurate highs.

Rotating Elliptical Lens: Each tweeter employs a Rotating Elliptical Lens that allows you to redirect and focus the high frequencies for pinpoint imaging and clear detail, even from off-axis factory speaker locations.

Anti-Diffraction Tweeter Post: The Anti-Diffraction Tweeter Posts are shaped like a funnel to minimize driver "bounce back", resulting in less distortion.

Mounting Rings: The supplied plastic mounting rings allow the speakers to be installed in 5"x7" or 6"x8" openings.
