Infinity Alpha 603CF

The Infinity Alpha 603CF car component speakers are a two-way system designed for in-vehicle installation. They offer a continuous power output of 90W RMS and a frequency range from 60Hz to 20kHz. The woofer uses the patented Plus One cone, which provides a more powerful low-frequency output thanks to its larger surface area. Clean and natural highs are delivered by the silk dome tweeter, which eliminates unwanted sound harshness. Thanks to their 90dB sensitivity, the speakers can play sufficiently loud even with less powerful amplifiers.

Plus One cone for stronger bass

The woofer is fitted with a polypropylene cone featuring the patented Plus One architecture. This technology provides a larger effective cone area compared to speakers of the same nominal size. The result is higher sensitivity and a noticeably stronger low-frequency output, which you will appreciate when listening to music with a prominent bass line. The set also includes two crossovers, which ensure the signal is correctly divided between the woofer and the tweeter.

Natural high-frequency sound

The Alpha 603CF model is equipped with a 19mm tweeter that stands out from commonly used types. It uses an edge-driven silk dome, which effectively dampens resonances and ensures a smooth and natural high-frequency response. This keeps the sound clean and free from unwanted harshness, even at higher volume levels. The sound signature thus retains its character throughout the entire dynamic range.

Installation and wide compatibility

The speakers are designed to be compatible with standard mounting holes in passenger cars, compact cars, and lorries. The mounting depth is 48mm. The package contains all the necessary accessories, including threaded adapters for flush mounting, which simplify installation in standard openings in the vehicle's doors or dashboard. Connection is made via classic speaker terminals.
