About the Infinity Reference 4012i

You probably spend more time listening to music in your car than in your home. Why not enjoy home speaker sound quality when you're on the road?

Infinity Reference 4012i 4" speakers feature silk dome tweeters that would be right at home in your living room speakers. These sweet-sounding domes deliver crisp, clear response, yet won't fatigue the ears.

Infinity designed their Plus One+ woofers with more surface area than other 4" speakers, for higher efficiency and improved bass output. A sturdy rubber Hi-roll surround allows plenty of room for the cone to move in its non-resonant powder-coated steel basket.

Settle into the driver's seat and make the most of your daily drive time with the exceptional sound of Infinity Reference speakers.

Product Research

Features

Plus One+ Woofer Cones: Each speaker uses a cone significantly larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and a significant increase in efficiency.

Woofer Materials: Each woofer is constructed from Injection-Molded Polypropylene. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. It is also lighter weight and more rigid for decreased distortion and improved bass response.

Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.

3/4" Silk Dome Tweeters: Each speaker uses a 3/4" edge-driven silk dome tweeter for smooth, accurate highs.
