Plus One Woofer Cones: The Plus One speaker 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: These speakers are marketed as 6-1/2"; they
will fit in standard 6-1/2" speaker openings, 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 1.878" and the mounting height becomes 1.066".
Edge Driven Dome Tweeters: Each speaker has a 1"
Edge-driven textile soft dome tweeter. 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 tweeter also has an adjustable
output level, +0 dB (flat) and +3 dB.
UniPivot Tweeter: The tweeter is angled and can be rotated
about 315° after installation. This allows you to direct the tweeters toward the
listeners, very useful for speakers mounted low in a door.
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 your speaker wire provides 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 2-ohm load.
Terminals: The input terminals are gold-plated set screws that
will accept up to 12 gauge bare wire.
Power Handling: Although Infinity lists the RMS power
handling as 75 watts, they also list the recommended power range as 5-125 watts
RMS. We've opted to list the more conservative 75 watt RMS figure on the
