Infinity Kappa 303S 3" Midrange Speakers

The Infinity Kappa 303S 3" midrange speakers add a dedicated midrange driver to a Kappa component system, delivering robust vocal and instrument detail in a compact 3" package.

• 3" glass fiber cone midrange: Maintains cone shape under higher power to sustain midrange presence and reveal vocal and instrument nuances.
• Impedance: 3-ohm impedance optimized for integration with Kappa component crossovers, aiding consistent, clear signal transfer.
• Power handling: Handles up to 55 watts RMS (165 watts peak) per driver, aligning with other Kappa components for cohesive dynamics.
• Frequency response: 200–15,000 Hz coverage focuses on midrange and upper vocal/harmonic content for intelligibility and body.
• Sensitivity: 93 dB @ 2.83V, enabling meaningful output with standard car audio amplifiers.
• 3-way compatibility: Crossovers included designed for Kappa Series systems and switchable to 3-way mode with 603CF, 503CF, or 693CF (not compatible with older Kappa systems).
• Included crossover bandpass: Bandpass crossovers integrate with your Kappa crossover network for clean midrange routing.
• Warranty: 3-year warranty for long-term confidence in performance.
• In the box: Includes 2 midrange drivers, grilles, grille frames, crossovers, wiring, mounting hardware, and installation kit.

In a proper Kappa component installation, the 303S pair fills the midrange channel between the tweeters and woofers, yielding clearer vocals and more natural instrument detail. The 3-ohm design and 55W RMS rating align with Infinity’s crossovers and bandpass options for a cohesive 3-way system, while 93 dB sensitivity helps you achieve substantial output with a modest amplifier. The included grilles, crossovers, and installation hardware simplify mounting and integration within a high-performance Kappa front stage, backed by a 3-year warranty.
