4″ (100mm) Two Way Car Speaker

New Alpha Series speakers make signature Infinity performance remarkably inexpensive. Injection-molded Polypropylene woofers provide a strong foundation of bass and midrange frequencies, and PEI Balanced dome tweeters complete the full-range sound with crisp, high-end frequencies. Speakers are remarkably transparent at the top with vocals, horns and strings and deliver big bass with plenty of slam. There are Five Alpha models for easy installation in any vehicle, whether it’s a truck, compact or limo. In addition to passing demanding reliability and environmental testing, all speakers are individually voiced by some of the world’s best transducer engineers to authenticate the Infinity sound.

Features

Injection-molded polypropylene cone

The polypropylene woofer cone in Alpha speakers is engineered for superior rigidity and sensitivity. The result is increased low-frequency output and richer, more robust musical character.

NEW Infinity ID design

The new Infinity Alpha speaker has more elegant ID design for young audio junkies who desire an upgrade to their factory sound and style.

Competitively Tuned

Infinity employs second order filters for tweeters and sophisticated two-way crossovers for multi-element speakers and component systems resulting in higher power handling and added flexibility and accuracy when tuning speakers. A higher quality crossover allows Infinity’s wizards to consider speaker acoustic characteristics as well as specifications when tuning the Infinity sound.

Rigid Reliability Testing

Infinity Alpha series speakers have to go through environmental testing that would destroy other speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time.

Value Engineered

With the goal of providing access to great Infinity sound at an affordable price, our engineers valued engineered the Alpha Series speakers to deliver great sound at an affordable price.
