Edge-driven tweeter design
Infinity employs an edge-driven design for an open sound and minimal distortion at high volume. Prepare for a more clearly defined soundstage as the natural details in your music come alive.
Famous Plus One+ technology
The Primus polypropylene woofer employs Infinity’s proprietary Plus One woofer design for solid, punchy bass. Infinity extends the cone right up to the edge of the basket, for more surface area — and a bigger cone means more bass when your music needs it.
Make the most of your power
Infinity’s special “true 4-ohm architecture” uses a low-impedance voice coil to safely draw extra power out of your factory radio, aftermarket stereo, or an external amplifier, so you’ll get a stronger and clearer sound.
