6" x 9" three-way loudspeaker with Plus One woven glass-fiber woofer cone and edge-driven MMD dome midrange and UHF tweeter.Plus One woofer cones - This patent pending technology deliver a cone with more surface area than competing models of the same size. The result is increased bass output and higher efficiency. Edge-driven MMD dome midrange - These are not commonly used W-domes, but fully edge driven domes like those found in fine home audio loudspeakers. This much larger voice coil increases power handling and provides better sonic integration with the mid-woofer. Woven glass fiber woofer cone material is extremely stiff, minimizing cone flex which yeilds very low distortion and improved clarity, an Infinity trademark. True Four Ohms� All Kappa speakers feature two ohm voice coils. Original factory-installed speaker wiring in many cars is 18-22 gauge. This wire, and heating in the voice coil when power is applied, increase the impedance �seen� by the amplifier or head unit. The impedance of Kappa Speakers has been adjusted to compensate for this increase and can be safely driven by any head unit. Computer-optimized voice-matched outboard passive crossovers - Each Kappa multielement and component system features an outboard crossover that has been voice-matched for flawless performance with incredible detail and accuracy. UHF Tweeter - To ensure response clear out to 30kHz, both three-way multielements use a UHF tweeter. Adjustable tweeter level-Each Kappa multielement features a user adjustable tweeter level control. On the two-way models, simply rotate the tweeter to add or subtract 3dB output. On the three-way models, it is the simple push of a button right on the tweeter faceplate.
