Edge-driven tweeter design

Infinity employs an edge-driven design in their soft dome tweeter for a smoother, more open response and minimal distortion at high volume. With the addition of a piezo supertweeter in this 3-way speaker, prepare for a more clearly defined soundstage as the details in your music come alive. 

Famous Plus One+ technology

This Primus polypropylene woofer delivers solid, punchy bass, thanks to Infinity's proprietary Plus One+ woofer design. Infinity extends the cone right up to the edge of the basket, giving you lots of 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 clearer sound. Grilles are included.

Product Research

Features

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.

Impedance: The Primus Series speakers feature 2.7Ω voice coils to compensate for the high in-line resistance of small gauge factory wiring and extract every watt from the factory receiver, increasing overall system output and efficiency (relative to 4-ohm speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers capable of powering a lower impedance load.
