Cablejat
Connect the speaker terminals to the appropriate outputs of your amplifier or crossover network. Pay close attention to positive (+) and negative (-) terminals to maintain correct audio phase. The speaker has an impedance of 3.5 Ohms. Ensure your amplifier is stable at this impedance. When connecting wires to the speaker terminals, apply gentle, firm pressure to secure the connection without overtightening, which can damage the terminals.

Pautes de funcionament
The Kappa Perfect 300m speakers are designed to reproduce midrange frequencies (150 - 10,000 Hz) within your car audio system. They function as passive components, receiving amplified signals from your car amplifier, often routed through a crossover network to ensure they only receive the appropriate frequency range.
Manipulació de potència
- Gestió de la potència RMS: 37.5 watts per speaker (75 watts per pair)
- Tractament de potència màxima: 150 watts per speaker (300 watts per pair)
- Recommended Power Range: 45 - 75 watts RMS per channel
To prevent damage, ensure your amplifier's output power does not consistently exceed the speaker's RMS power handling. Operating within the recommended power range will provide the best sound quality and speaker longevity.
Manteniment
The Infinity Kappa Perfect 300m speakers require minimal maintenance to ensure long-term performance.
- Neteja: Gently wipe the speaker grilles and surrounds with a soft, dry cloth. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the speaker materials.
