Kappa Perfect6.1

Features

The perfect .1 woofer

employs the proprietary Focused-Field T-Pole Motor™ design, which concentrates the motor’s magnetic energy at the voicecoil gap, avoiding the losses and lack of symmetry that cause audible distortion. The woofer cone’s anodized-aluminum construction provides extremely high stiffness for its moving mass, allowing the Perfect .1 to reproduce deep-bass frequencies at surprisingly high levels, relative to cone size. The cone and motor structure are mounted in a cast-aluminum frame that maintains precision tolerances under the demanding vibration and temperature extremes of the mobile environment.

The perfect .1 tweeter

features an anodized-aluminum dome suspended by a rubber surround and is driven by a powerful neodymium magnet. The unique rubber surround helps reduce the resonant frequency of the tweeter, thereby ensuring a linear transition to the midrange driver at the critical midband crossover frequency. The tweeter uses the Infinity I-Mount™ design (patent no. 5,859,917), which allows for easy installation.

The passive crossover

uses a 24dB/octave Linkwitz-Reily fourth-order acoustic alignment. This alignment allows greater mounting flexibility by eliminating the frequency response problems caused when the woofer and tweeter are mounted on different planes.

Air-core inductors

reduce magnetic saturation under high-power conditions, and polypropylene capacitors ensure near-ideal characteristics with low resistance and inductance, even at the highest reproduced frequencies.
