About the Polk EX340

Polk's EX3 speakers combine high efficiency with good power handling — they'll sound great with any in-dash receiver (even a "factory" model) or powered by an external amp. The EX340 4" speaker features an ingenious Rotating Elliptical Lens that directs the high-frequency response from its 3/4" soft dome tweeter. You can "dial in" imaging improvements, depending on your factory speaker locations.

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.
