Overview
The Infinity Kappa 90CSX 6x9" Component Speakers System is a high-performance 2-way component system engineered for audiophiles demanding reference-quality sound. With 100W RMS power handling and a 2.5-ohm impedance, this system extracts every watt from your amplifier for exceptional output. The patented Plus One glass fibre woofers deliver tight, robust bass, while the edge-driven textile dome tweeters with oversized voice coils provide silky smooth highs. The 3-way upgradeable crossover and UniPivot tweeter with level control offer unmatched installation flexibility, making this system ideal for discerning listeners.
Key Features:
- 100W RMS / 300W Peak Power – High power handling delivers dynamic, distortion-free performance for demanding listening sessions and aftermarket amplifier compatibility.
- 2.5-Ohm SLI High-Output Design – Low impedance architecture extracts every watt from the amplifier, compensating for added resistance in factory-installed wiring.
- 45Hz – 35kHz Extended Frequency Response – Wide range captures deep bass and extends beyond the typical hearing limit for enhanced high-frequency detail.
- Patented Plus One Glass Fibre Woofers – Lighter and stiffer cones with more cone area than competitors deliver increased low-frequency output and higher efficiency.
- Edge-Driven Textile Dome Tweeters – Oversized voice coils with broader, smoother high-frequency response and increased thermal power handling for high-volume enthusiasts.
- UniPivot Tweeter with 270° Rotation – Angled tweeter rotates after installation for precise imaging and soundstage elevation in low door mount locations.
- Push-Button Tweeter Level Control – Switch between 0dB flat and +3dB to custom tune high frequencies for on- and off-axis speaker placement.
- 3-Way Upgradable Crossover – Gap-switchable crossovers accommodate an optional midrange upgrade, converting the 2-way system into a perfectly balanced 3-way system.
- 93dB Ultra-High Sensitivity – Achieves excellent volume with superb musicality from as little as 5 watts RMS, ideal for upgrading factory speakers.
- Audiophile-Grade Crossover Components – Individually tuned with audiophile-grade inductors and capacitors for detail and accuracy unmatched in this class.
Ideal For
- Car audio enthusiasts seeking reference-quality component sound
- Vehicles with 6x9" factory speaker locations requiring component upgrades
- Drivers wanting high-output performance from factory head units
