Infinity Kappa 603CF

Features

Plus One Woofer Cones: The Plus One woofer cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.

Terminals: The woofer input terminals are set screws that will accept up to 12 gauge bare wire.

Mounting Applications: These speakers are marketed as 6½"; they will fit in many standard 6½" speaker openings (just over 5" diameter), but do not use the standard 6½" speaker bolt pattern. In order to install the woofers in standard 6½" speaker openings you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6½" mounting holes and the Ford non-symmetric four hole pattern, as well as other non-standard patterns. When using the brackets the depth becomes 1.884" and the mounting height becomes 0.794".

High-Output Design: The high output 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring and extracts every watt from factory receivers, increasing overall system output and efficiency (relative to 4Ω speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers, designed to power a 3Ω load.

Edge Driven Tweeters: The ¾" edge-driven tweeters use silk domes. An edge-driven tweeter has better dispersion characteristics and allows for a lower crossover frequency than typical tweeters of the same size, which improves imaging. The result is improved vocals and musical clarity. The 6" speaker wire attached to each tweeter is terminated with male quick-slides (0.187" positive and 0.110" negative).

Tweeter Mounting: The I-Mount tweeter mounting system and Starfish mounting brackets give you several different ways to mount the tweeters:

• I-Mount Tweeter Mounting System: The tweeters can be surface or flush mounted with Infinity's innovative I-Mount system:
  • Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
  • Flush Mount: Flush mounting is made easy through the use of the threaded flush-mount adapter and plastic locking nut. Once a cutout is made, the flush-mount adapter (with the tweeter installed) is inserted into the hole. The large plastic locking nut is threaded onto the adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging.
• Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the grilles:
  • Surface Mount (behind grille panel)
  • Flush Mount (behind grille panel)
  • Bottom Mount (to grille panel)
  • Flush Mount (in-dash location)

Tweeter Mounting Dimensions:

Crossovers: The input, tweeter output, and woofer output wires are attached to the crossovers; each is 8" long and terminated with tinned bare wire. Each crossover has a tweeter output level switch; choose between flat and -3dB. Each also has a 2-way/3-way switch used when adding the matching midrange to upgrade the system to 3-way.

Crossover Dimensions:

• Width: 4⅛"
• Height: 1"
• Depth: 1⅞"

3-Way Upgrade: The included system crossovers are gap-selectable, to accommodate a midrange upgrade. The optional Kappa 203S and 303S midrange (item numbers 108K203S and 108K303S, both sold separately as a pair) include the band pass crossover to upgrade this two-way system to a three-way system with perfect tonal balance.
