Designed and built for audiophile tastes, this Kappa 90csx 6"x9" component speaker system benefits from a refined design, Infinity's proprietary technology, and premium materials to deliver uncompromised audio quality. Edge-driven dome tweeters Infinity employs an edge-driven design in their soft dome tweeters for a smoother, more open response and minimal distortion at high volume. Prepare for a more clearly defined soundstage and marvel as your music seems to come alive across your dash. Woofers enhanced with Plus One+ technology Bring on the bass. Kappa's glass fiber woofer will hold its shape when the power's cranked up, so you still get punchy and defined bass. Glass fiber weighs less than traditional materials, so you don't need a ton of power to drive this woofer either. Infinity's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you lots of surface area — and a bigger cone means more bass to complement the superior high-frequency response. Premium crossovers Infinity holds their external crossovers to the same standards as the rest of this speaker system. Premium components shape the distinctive Kappa sound and bring out all the details that make your music sound real. These crossovers will easily accommodate an upgrade to a 3-way system if you'd like to add Infinity's optional Kappa 20mx 2" midrange drivers. Awesome power handling, no matter the system These 2.5-ohm speakers boa
