2. Caratteristiche principali
- Tweeter a cupola in seta con guida laterale: Equipped with oversized voice coils, these tweeters provide smooth high-frequency reproduction with excellent thermal power handling and 40kHz high-resolution audio capability.
- Plus One™ Glass Fiber Woofer Cones: Lighter and stiffer than conventional cones, these woofers offer increased cone area for enhanced low-frequency output and higher efficiency.
- Adjustable Tweeter Output Level: A push-button on the angled tweeter allows for 0dB or -3dB output level control, enabling optimization of system linearity based on the installation location.
- Rotatable Tweeters: For coaxial models (and applicable component tweeters), the tweeters can be rotated 270° after installation, providing imaging options and the ability to elevate the soundstage.
- Compact Crossover Networks: The 2-way component system crossovers are compact and feature 2-way and 3-way selections, allowing for future upgrades with an optional 2" or 3" midrange speaker.

4.3 Montaggio dei tweeter
The tweeters can be flush-mounted or surface-mounted depending on your vehicle and desired soundstage. Refer to the specific mounting hardware instructions for detailed steps.
- Choose an optimal location for the tweeters, ideally at ear level.
- Connect the tweeter wires to the crossover network.
- Secure the tweeter using the appropriate mounting method.

4.4 Crossover Network Connection
The crossover network separates the audio signal into appropriate frequency ranges for the woofer and tweeter. Connect the input from your amplifier/head unit to the crossover, then connect the woofer and tweeter outputs from the crossover to their respective speakers.
- Collegare il amplifier output to the 'INPUT' terminals on the crossover.
- Connect the woofer to the 'WOOFER' terminals on the crossover.
- Connect the tweeter to the 'TWEETER' terminals on the crossover.
- Assicurarsi che la polarità sia corretta (+ con + e - con -) per tutti i collegamenti.

4.5 Impostazioni crossover
The crossover network includes switches to adjust the tweeter output level and configure for 2-way or 3-way systems.
- Tweeter Level (0dB / -3dB): Adjust this switch to match the tweeter output with the woofer and your vehicle's acoustics. Start with 0dB and adjust to -3dB if the highs are too prominent.
- System Configuration (2-way / 3-way): Set this switch to '2-way' for the standard component system. If you integrate an optional midrange speaker, switch to '3-way' and connect the midrange to the dedicated terminals (if available on your specific crossover model).
5. Funzionamento
Once installed, the Kappa 603CF system operates in conjunction with your car's head unit and amplifier. Adjust audio settings on your head unit (e.g., bass, treble, balance, fader) to fine-tune the sound to your preference. Experiment with the tweeter level switch on the crossover to achieve the desired tonal balance.
6. Manutenzione
The Infinity Kappa 603CF speakers require minimal maintenance.
- Keep the speaker grilles clean and free of dust or debris. Use a soft, dry cloth for cleaning.
- Evitare di esporre gli altoparlanti a umidità eccessiva o alla luce solare diretta per periodi prolungati.
- Do not apply any chemicals or abrasive cleaners to the speaker cones or tweeters.
- Controllare periodicamente tutti i collegamenti elettrici per accertarsi che siano sempre saldi.
7. Risoluzione Dei Problemi
