Infinity PR9613IS

6x9" Three-way Multi-element Speaker Set

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 super clear 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.


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. Hi-roll rubber surrounds using automotive grade materials result in cleaner reproduction and higher durability whether it's easy listening or time to show and shine.

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.

Harman Standard Reliability Testing
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.

Infinity at an Affordable Price
This is Infinity—one of the most innovative and legendary companies in audio. Infinity is one of the top-selling car speaker brands in the world—obviously, this is no coincidence.
