## Overview

The Infinity Primus 6512 is a 6.5-inch 2-way coaxial car speaker featuring patented Plus One polypropylene woofers and edge-driven silk dome tweeters. Designed with a true 4-ohm impedance for optimal amplifier performance, it delivers clear highs and powerful bass. Engineered for easy installation across various vehicles, these speakers are individually voiced by expert engineers to provide superior sound quality that significantly outperforms standard OEM speakers.

## Description

New Primus speakers feature our patented Plus One polypropylene woofers which feature more radiating cone area for increased output and edge-driven tweeters for better high frequency dispersion. Speakers are remarkably transparent at the top with vocals, horns and strings and deliver big bass with plenty of slam. Long story short: superior sound top to bottom. True 4 ohm architecture gives the amplifier room to reach peak power for increased depth and detail. There are seven Primus models for easy installation in any vehicle, whether it's a truck, compact or limo. In addition to passing demanding reliability and environmental testing, all speakers are individually voiced by some of the world's best transducer engineers to authenticate the Infinity sound. It's not a coincidence that Infinity is one of the world's top-selling car audio speaker brands.

Review: Excellent - I installed these in my son's Civic as the original equipment speakers are about as CHEAP as one can imagine! They literally didn't weigh much more than 1 ounce, which has to be hard to do with a 6.5" speaker! The magnets on the original speakers were roughly 1" in diameter though there was no mass to them and the sound quality in that car was HORRIFIC before. I install custom, high end stereos for people when I am feeling well enough to do so (disabled veteran) and I've been selling Infiniti's high end speakers for almost 20 years. These are not their top line speaker but honestly, unless you were to drive these very hard with an amplifier, you wouldn't know they're pretty much Infiniti's budget line of speaker! These are in a Civic in the doors as well as the rear deck. There is a 25w/channel amplifier driving them as well as a powered 10" subwoofer underneath the driver's seat. The sound quality in this car is now acceptable, and my son could not be more thrilled with the sound! With the original speakers he had to have the stereo up about as loud as it would go just to be able to hear music on the highway. With these he has the stereo on no more than 15-20% volume and the sound is excellent. For anyone who is looking for a clean sounding speaker with reasonable mid-bass response and a crystal-clear tweeter for the upper mids and highs, you will not regret buying these speakers. Infiniti indeed makes speakers even better than these, but for the dollar, these speakers are OUTSTANDING! Whether you're only replacing the original speakers or even if you're adding an aftermarket head unit, a 4-channel amplifier of moderate power and a powered subwoofer these speakers will give you sound quality infinitely better than the garbage OEM speakers as well as give you a tremendous gain in volume without sounding "tinny" or distorting so long as the amplifier driving them is properly matched to the speakers. You would literally believe that much more money was spent on this stereo in this car, but it is exactly what a kid in college can afford to buy. It is nice to get a great "bang for your buck" every once in a while, and these speakers provide that bang for the buck!
Review: Ininity Quality and Clarity - They deliver excellent sound quality for my anemic OEM Subaru headunit. They pair really well with 6x9 Infinity Kappa front speakers on my '22 Subaru Outback Wilderness. No noticeable speaker distortion or breakup at all.
