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 Woven-Glass-Fiber
Woofer Cones: The Plus One speakers use cones approximately 30% larger than
other speakers of the same size. This is accomplished by using a new basket
design and hi-roll surround. The Plus One design offers greater bass output and
a significant increase in efficiency. The woven-glass-fiber material is very
light and extremely stiff, minimizing cone flex. This results in very low
distortion and improved clarity.
Motor Structure: The new Kappas
use a Neodymium motor structure with an integrated heat sink. This design
provides a massive amount of energy while minimizing mounting depth and magnet
diameter. The integrated heat sink cools the motor structure efficiently, thus
increasing power handling while reducing distortion.
Emit Tweeter and MMD Dome Midrange:
Each speaker has an Emit tweeter and an MMD (Metal Matrix Diaphragm) dome
midrange. The benefit is increased power handling and reduced distortion at high
output. This technology also allows for better integration with the woofer. The
tweeter has an adjustable output level, +0 dB (flat) and +3 dB.
SLI High-Output Design: This
high output 2 ohm design extracts every watt from today's high powered receivers
and amplifiers, increasing overall system output and efficiency (relative to 4
speakers include computer-optimized, voice-matched crossovers, using audiophile
quality air core inductors and polypropylene capacitors.
Crossover Connections: Each
crossover has a 11" input lead terminated with bare wire and two 18" output
leads, one for the woofer and one for the tweeters, terminated with female
quick-slides. The female quick-slides connect to the male quick-slides on the
speaker. The positive terminal on the woofer input is 0.248" and the negative is
0.191". The positive terminal on the tweeter input is 0.205" and the negative is
Crossover Dimensions: L=4.265",
Infinity's Intermount III mounting system allows the 63.7i speakers to fit a
variety of 6-1/2" and 6-3/4" applications. Two adapter rings are included for
