Frequently Asked Questions - Kappa Perfect 5.1 INFINITY

What amplifier power is recommended for the Kappa Perfect 5.1?

A two-channel amplifier with at least 50W RMS per channel is recommended for optimal performance.

Can I bi-amp the Kappa Perfect 5.1 with an electronic crossover?

No, bi-amping is not recommended. The passive crossover uses a Linkwitz-Riley 4th order alignment that cannot be replicated with electronic crossovers.

What are the best mounting locations for the speakers?

Kick-panel mounting provides the best staging and imaging. Alternative locations include doors and dash (refer to figures in the manual).

How do I mount the tweeter?

The tweeter can be surface-mounted or flush-mounted. See Figures 5 and 6 in the manual for details.

Can I mount the woofer in a factory speaker location?

Yes. The P5.1 woofer can be mounted in factory locations, but the grille and grille tray should be omitted.

How do I adjust the crossover?

The crossover has jumpers for adjustment (see Figure 11). Settings include flat, +5dB, and -4dB tweeter level.

What is the frequency response of the system?

The system response is 80 Hz - 23 kHz (±3 dB).

Is professional installation required?

While the manual provides general instructions, professional installation is recommended if you lack experience with mechanical and electrical procedures.

What safety precautions should I take?

Avoid listening at high volumes to prevent hearing loss and to remain aware of traffic sounds.

How do I clean the speakers?

Clean with a dry, soft cloth. Do not use water or cleaning agents.

IMPORTANT

Installation of automotive stereo components can require extensive experience performing a variety of mechanical and electrical procedures. Although these instructions explain how to install a Kappa Perfect component system in a general sense, they do not show the exact installation method for your particular car. If you feel you may not have the necessary tools or experience, ask your authorized Infinity car audio dealer about professional installation options.

WARNING

Playing loud music in your automobile can permanently damage your hearing as well as hinder your ability to hear traffic. We recommend listening at low volume while driving. Infinity accepts no liability for hearing loss, bodily injury or property damage resulting from use or misuse of this product.

A NOTE ABOUT SYSTEM PERFORMANCE

For the best performance possible, the Kappa Perfect components should be used with a two-channel amplifier with output power of at least 50W RMS per channel. The passive crossover contains impedance-compensating circuitry and has been computer-optimized for the flattest possible frequency response with the tweeter flush-mounted, on-axis with the listener. The combined responses of the speakers and passive crossover constitute a 4th-order Linquitz-Riley acoustic alignment and cannot be duplicated with any electronic crossover currently available for car audio use. Consequently, bi-amping a Perfect component system with an electronic crossover is not recommended.

SPEAKER PLACEMENT

Figures 1–4 show possible speaker placements in the order of most desirable to least desirable. Kick-panel mounting will provide the best staging and imaging in most vehicles.
