Kenwood Excelon speakers incorporate technical know-how and advanced materials to give your music the full, rich sound it deserves. These full-range speakers sport a diamond-array pattern etched into their woofers that increases the strength of the carbon-polypropylene cone for improved dynamic response and lower distortion. The butyl rubber surround resists weathering, providing reliable support that keeps your music playing, no matter what.

The KFC-X1730 6-3/4" full-range speakers feature 1" silk dome tweeters that deliver all the high-frequency details without sounding harsh. Because of their specially designed magnetic circuitry and neodymium magnets, these compact tweeters use less steel in their construction than most tweeters, so you hear more accurate response.

Note: Kenwood describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Why replace your factory speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Product Research


Woofers: The woofer cones are constructed of Carbon-PP (polypropylene) with a diamond array pattern.  The woofers feature butyl rubber surrounds for a smoother response and improved durability.

Tweeters: Each speaker uses a 1.0" Silk soft dome tweeter for smooth, accurate highs.

Adapter Ring: The included adapter ring expands the woofer's compatibility to include the 3-hole 6-3/4" pattern used by GM and Chrysler, the standard 3-hole 6-1/2" pattern, and Ford's 4-hole 6-1/2" pattern.

Warranty Note: Although these speakers come with a 1-year warranty card, they are covered by the Kenwood eXcelon 2-year warranty.
