Infinity Kappa Perfect 900X 6" x 9" Motorcycle Speakers

The Infinity Kappa Perfect 900X is a pair of premium 6" x 9" two-way speakers engineered for motorcycle audio upgrades. It is designed for selected Harley-Davidson Touring Series motorcycles from 2014 and later. The system provides a purpose-built solution for riders seeking a larger bag-lid speaker upgrade with motorcycle-focused weather resistance.

With 100 watts RMS and 300 watts peak power handling, the Kappa Perfect 900X is intended for systems that need substantial output capability from a compact motorcycle installation. Its 95dB sensitivity and 3-ohm impedance support efficient performance when paired with appropriately compatible amplification. The stated 50Hz to 20kHz frequency response covers bass, midrange, and treble information for full-range playback.

The speaker uses a lightweight basalt-fiber woofer cone with Harman's Plus One technology. This cone approach increases the effective cone area while maintaining a light diaphragm material. A rubber surround supports the woofer assembly for mobile outdoor use.

A 1-inch edge-driven polyphenylene sulfide dome tweeter handles high-frequency reproduction. Its removable design allows the system to be configured as a coaxial speaker or converted for component-style installation using the included tweeter kits. This flexibility lets installers choose between an integrated speaker layout and more separate tweeter placement.

The Kappa Perfect 900X is built with a neodymium magnet structure to reduce weight while supporting efficient operation. The speaker front is rated IPX5, while the rear side is described as weather resistant. Included mounting brackets, templates, grilles, crossover pigtails, and hardware support installation in its intended motorcycle application.
