Infinity Alpha 603C

The Infinity Alpha 603C two-way component speakers are designed to upgrade the sound in your car. They use a patented Plus One polypropylene cone, which provides higher sensitivity and more powerful bass thanks to its larger effective area. The silk dome tweeter ensures clean reproduction of high tones. The speakers offer a continuous power of 90W RMS and are compatible with standard car radios and external amplifiers thanks to their 4 Ohm impedance.

Patented cone for more powerful bass

Infinity Alpha 603C speakers use the patented Plus One cone architecture. The Plus One architecture provides a larger effective surface area compared to standard speakers of the same diameter. The result is higher sensitivity, a stronger bass response, and a more distinct musical character overall. The cone itself is made of polypropylene. This material ensures resistance to humidity and temperature fluctuations typical in a car environment.

Clean and smooth high-frequency reproduction

The edge-driven silk dome tweeter takes care of detailed high-frequency reproduction. This design delivers a smooth and natural response without the unpleasant harshness that can occur with other types of speakers. The sound thus retains its clarity and intelligibility even at higher volume levels.

Power and wide compatibility

With a continuous power of 90W RMS and a peak power of up to 720W, the speakers have enough headroom for dynamic listening. A high sensitivity of 90dB means you can achieve high volume even when connected to less powerful factory car radios. The nominal 4 Ohm impedance is compatible with both standard head units and external amplifiers. Additionally, the mounting is designed to fit a wide range of vehicles, from cars to lorries.
