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 a significant increase in efficiency.
Formed Glass Fiber Woofer Cones: The formed glass fiber cone
material is very light and extremely stiff, minimizing flex. This results in very
low distortion and improved clarity.
iCGM frames: The Kappa series speaker baskets are made of
composite Injected Carbon Glass Matrix (iCGM). iCGM is lighter and stronger than
stamped steel; it retains its shape, even when mounted on uneven surfaces (common
in car mounting locations), plus offers exceptional damping of any resonances.
Woofer Size: This component set is marketed as having 6-1/2"
woofers; they will fit in standard 6-1/2" speaker openings (approximately
5" diameter), but do not use the standard 6-1/2" speaker bolt pattern.
In order to install them in standard 6-1/2" 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 6-1/2" mounting holes and the Ford non-symmetric
four hole pattern. When using the brackets the depth becomes 1.885" and the
mounting height becomes 0.773".
Terminals: The woofers' input terminals are gold-plated set
screws that will accept up to 12 gauge bare wire.
High-Output Design: The high output 2-ohm 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 4 ohm speakers). The speaker's 2.0-ohm impedance combined
with the impedance of the factory speaker wire presents a true 4-ohm load to your
connected headunit or amplifier. The speakers also benefit from increased power
when you upgrade the wire and add aftermarket amplifiers, designed to power a
Edge Driven: The 3/4" edge-driven tweeters use textile
soft 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.
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
- 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
- Surface Mount (behind grille panel): Once
the Starfish bracket is trimmed, it is screwed to the mounting
surface behind the grille panel. Then, the tweeter is inserted
into the bracket and locked into place.
- Flush Mount (behind grille panel): Once the
Starfish bracket is trimmed, it is dropped into the cutout in the
mounting surface behind the grille panel. Then, the tweeter is
inserted into the bracket and locked into place.
- Bottom Mount (to grille panel): Once the
Starfish bracket is trimmed, it is secured to the underside of
the grille panel. The tweeter must be inserted into the bracket
and locked into place before the bracket is mounted.
- Flush Mount (in-dash location): Once the
Starfish bracket is trimmed, it is dropped into the cutout in
the dash. Then, the tweeter is inserted into the bracket and
locked into place.

Crossovers: The crossovers use low-loss air core inductors,
low-hysteresis polypropylene capacitors, and high-quality resistors. Each crossover
has a tweeter output level switch; choose between flat and +3dB.
Connections: Each crossover has set screw input and output
terminals that will accept up to 10 gauge bare wire.

Power Handling: Although Infinity lists the RMS power handling
as 90 watts, they also list the recommended power range as 5-200 watts RMS. We've
opted to list the more conservative 90 watt RMS figure on the specifications page.
