Infinity Primus 603CF 6.5″ (160mm) 2-Way Component Car Speaker 60W RMS / 180W Peak Harman Signature

The Infinity Primus 603CF component speaker system brings signature HARMAN sound tuning and award-winning design to your vehicle. By separating the mid-bass woofer from the silk dome tweeter, the 603CF creates a spacious soundstage with accurate imaging and detailed vocals.

1. Plus One™ Polypropylene Woofer Cones

Infinity’s patented Plus One™ cone technology provides a larger overall cone surface area compared to other speakers in its class. This extra cone area moves more air, resulting in punchier mid-bass output and enhanced low-frequency extension.

2. Edge-Driven Silk Dome Tweeters

The separate edge-driven silk dome tweeters deliver smooth, clear high frequencies. Positioned on the dashboard or A-pillars, these tweeters bring vocals and acoustic details right up to ear level.

3. High-Efficiency Output Architecture

Engineered for maximum sensitivity, the Primus 603CF extracts high sound output from low-power factory head units while easily handling higher output from aftermarket amplifiers.

4. In-Line Crossover Network

Equipped with compact in-line crossover modules, the system cleanly separates frequency bands between the woofer and tweeter, ensuring smooth tonal balance and zero distortion.
