With a smart design, reliable performance, and signature Infinity sound quality, this 4-inch car speaker brings crystal-clear sound to any vehicle—whether you drive a compact car, sedan, or van. Thanks to the powerful Plus One™ woofer, balanced PEI dome tweeter, and wide frequency response, you'll experience music exactly as it was meant to be heard: powerful, clear, and consistently balanced.
Deep bass and clear midrange
The Infinity Alpha 403F features the proven Plus One™ woofer cone , which is larger than standard woofer surfaces in the same size class. This allows it to move more air and produce deeper bass and warmer midrange. So your favorite music sounds fuller, even at lower volumes.
