Looking for a more moving audio experience? Take Infinity?
car audio for a ride. Innovative materials and breakthrough
engineering have always put Infinity products out in front
of the competition?s. So expect extreme output from us. But be
prepared for accuracy and detail that may surprise you. The
Kappa line of premium loudspeakers ? which incorporates the
very best in high-end design and proven technology ? has long
been one of the world?s most recognized and admired.

New Kappa loudspeakers take car audio speaker technology to a
whole new level with features such as Plus One? (patent pending)
cones; true-four-ohm topology; UniPivot? (patent no. 6,002,780)
edge-driven tweeters; and industry-leading mounting systems,
including Intermount III (patent no. 6,505,705) and I-Mount?
(patent no. 5,859,917), and the Starfish? tweeter-mounting adapter.
With all this technology in a single speaker series, it?s no wonder
our competitors are scrambling to keep up.
For years, the design of upscale car audio speakers has been
loosely based on the design of at-home speaker systems, where
amplifiers are big and power is plentiful. The audio systems in new
cars are different. Almost all new systems include two-ohm
speakers and small, efficient amplifiers or head units designed
to drive them. Replacing those two-ohm factory speakers with
four-ohm models cuts the available power in half, and that?s
no upgrade. Kappa speakers are optimized for these new systems
and work beautifully with old-school aftermarket gear, too.
