Infinity’s glass fiber woofer cones are lighter and stiffer with more cone-area than the competition , delivering increased low-frequency output and higher efficiency..
Edge-driven textile dome tweeters - These are not commonly used W-domes, but edge-driven textile dome speakers that will deliver broader and smoother high frequency response..
High output 2.5 ohm ohm architecture with low impedance voice coils enables the speaker to extract every watt from the amplifier and deliver peak power with ease..
Infinity speakers have to undergo a testing process that would destroy lesser speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time..
Infinity is in the business of designing reference quality speakers, and Kappa car audio speakers are no exception..

Patented Plus One Polypropylene Woofers - Polypropylene cones with up to 35% more radiating cone area than other cones in the same class provide higher sensitivity, increased low frequency output and better tonal balance..
Edge-Driven Tweeters - Edge-driven tweeters deliver wider dispersion and smoother high frequency response with increased power handling for high- and mid-frequencies..
True 4 Ohm Architecture - True 4 ohm architecture with low impedance voice coils give the amplifier room to deliver peak power providing stronger and clearer sound with better depth and detail..
Infinity speakers have to undergo a testing process that would destroy lesser speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time..
Voicing of Speakers - Speakers are individually voiced to assure high quality audio versus “off-the-shelf” manufactured sound. This means that specifications as well as speaker characteristics are considered when tuning the Infinity sound..
