Built with home audio know-how

Infinity used technology from their popular Primus home speakers to design car speakers that offer strong performance without breaking the bank. A 1" edge-driven, textile dome tweeter and a 5/9" piezo supertweeter broadcast smooth high frequencies while the oversized, Plus One+ polypropylene woofer creates solid bass. The speakers' 3-ohm impedance safely draws a little extra power out of your factory radio, aftermarket stereo, or an external amplifier, so you'll get a little more punch from your system. 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.

Edge Driven Dome Tweeters: Each speaker has an edge-driven textile soft dome tweeter. An edge-driven tweeter has better dispersion characteristics and allows for a lower crossover frequency than typical tweeters of the same size, which improves imaging. The result is improved vocals and musical clarity.

3-ohm Voice Coil: The Primus Series speakers feature 3-ohm 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 2-ohm load.

Power Handling: Although Infinity lists the continuous average RMS power handling as 90 watts, they also list the recommended power range as 5-200 watts RMS. We've opted to list the more conservative 90 watt RMS figure on the specifications page.

Q
I am looking at this set of speakers to go in the rear deck of a 2005 Camry. Understand factory grilles have to stay in place, but it says a mounting bracket will have to be fabricated? Has anyone done this? If so what was the bracket made from and how difficult was it to make and mount?? I'm not enginner that's for sure! Thanks!
