KAPPASERIES
Thank you for purchasing an Infinity Kappa Perfect component system. The Kappa Perfect6.1 has been engineered to provide the most accurate sonic reproduction possible. Over the years, we at Infinity have listened to hundreds of automotive speakers and we think these are the best. We hope you agree.
This manual includes information that will make your installation
as simple and trouble-free as possible. It also provides detailed technical information that will help an experienced installer optimize speaker placement and crossover adjustment. Please study this manual before you begin your installation. Remember to send in your warranty registration card, and keep your sales receipt somewhere safe in case you need warranty service.
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 Perfect6.1 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 Perfect6.1 should be used with a two-channel amplifier with output power of at least 35W 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 4th-order Linquitz-Riley acoustic alignment and cannot be duplicated with any electronic crossover currently available for car-audio use. Consequently, bi-amping the Perfect6.1 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.
