Powerful and Detailed Infinity Alpha Sound

The ALPHA 603C is designed to offer high sound quality at an accessible price. The Plus One™ woofer design increases the membrane surface area, ensuring deeper and more precise bass.

The edge-driven silk dome tweeter provides smooth, detailed high frequencies and natural vocal reproduction, even at higher volumes.

This system is designed to maintain clear and dynamic sound across the entire frequency range – from 60 Hz to 20 kHz.

Effective OEM Audio System Upgrade

Thanks to their 90 dB sensitivity, the speakers work easily with factory car head units without the need for an additional amplifier. This allows for a simple sound upgrade without complex installation.

The component design allows for separate mounting of the woofer and tweeter, thereby improving the stereo soundstage and sound localization within the cabin.
