Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Plus One+ Woofer Cones: Each speaker uses a cone significantly
larger than other speakers of the same size. This is accomplished by using a unique
basket design and hi-roll surround. The Plus One+ design offers greater bass output
and increased efficiency.
Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the
woofers a greater range of movement, resulting in longer X-max and more bass output.
Textile Dome Tweeters: Each speaker uses an edge-driven textile
dome tweeter for smooth, accurate highs.
True Four Ohm Impedance Technology: The speaker's 3-ohm impedance
combined with the impedance of your speaker wire provides a true 4-ohm load to your
connected head unit or amplifier.
Power Handling: Although Infinity rates the 6402cfx speakers
at 45 watts RMS (continuous average), they also recommend amplifiers with a power
rating from 5 to 50 watts RMS.
Bottom Mounting: While the standard 4x6 adapters appear to be
easily removable, they are glued in place at four points around the perimeter (in
addition to the four screws, which are obvious). With the adapters in place, the
speakers fit many top mount standard 4x6 and metric 4x6 applications. If the adapters
are removed the speakers will fit additional top mount metric 4x6 applications, as
well as bottom mount metric 4x6 applications.
