Entry level car speakers with great sound performance at a competitive price.

The Alpha speakers make signature Infinity performance remarkably well. 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. It is 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 and Benefits:

Plus One Woofer Cone Architecture

Patented (US patent #7,548,631) Plus One cones provide more overall speaker-cone area than other speakers for the same size, resulting in higher sensitivity, increased low[1]frequency output and greater musical character.

PEI Balanced Dome Tweeter

This material provides crystal clear high frequencies free from harshness even at high output levels.

Edge-driven Silk Dome Tweeter (for Alpha 753T & Alpha603C & Alpha 603CF)

It has a full, edge-driven silk dome tweeter, which delivers a broader and smoother high frequency response, never-harsh regardless of output level than more commonly used w-domes.

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 .

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.

Competitively Tuned

For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That's not the case with Infinity. We don't only listen to our speakers against the competition -we voice them against each other to ensure each line has the consistent Infinity sound signature.
