Infinity Alpha 693M

The Infinity Alpha 693M car speakers are designed to replace or upgrade the factory sound system in your vehicle. They are 3-way coaxial speakers in a 6×9 inch format, featuring the patented Plus One diaphragm. This technology provides a larger active diaphragm area, resulting in higher sensitivity and a more powerful bass response. The PEI balanced dome tweeter ensures clean and crisp high notes. The result is detailed sound across the entire frequency range.

Patented diaphragm for more powerful bass

The speakers are equipped with a patented Plus One diaphragm, which increases the active cone area compared to conventional speakers of the same diameter. The direct result is higher sensitivity and a more powerful bass output. The woofer diaphragm itself is made of polypropylene, which provides a solid foundation for reproducing mid and low frequencies.

Balanced sound across all frequencies

The three-way design creates a comprehensive soundscape. While the polypropylene woofer handles the mids and bass, the PEI balanced dome tweeter completes the sound profile. The tweeter delivers clear high frequencies without distortion, even at higher volume levels. The frequency response covers a wide range from 45Hz up to 20kHz.

Power and easy installation

Thanks to their nominal 3-ohm impedance and high sensitivity, the speakers are suitable as a direct replacement for factory sound systems powered directly by the car stereo. The 65W RMS power rating and 195W peak power also mean they can be connected to an external amplifier. The speakers have undergone rigorous reliability and environmental testing.
