Infinity INFPRIMUS1270AM, Primus Series 12" 4 Ohm Subwoofer

Price-leading Infinity Primus car subwoofers were engineered to deliver high-output, low-distortion bass with power handling capability of up to 1200 watts peak power. These subwoofers feature lightweight yet stiff polypropylene woofer cones with hi-roll rubber surrounds to provide high efficiency and super durability to best interface with a variety of amplifiers. Finally, our subwoofers and loudspeakers are individually voiced by some of the world's best transducer engineers to ensure we achieve the signature sound that is unmistakably Infinity.

Highest Grade Materials for Super Reliability

Polypropylene cones and rubber surrounds using automotive grade materials give you clean reproduction and high durability whether it's easy listening on the boulevard or time to show and shine. It's all about the bass!

HARMAN Standard Reliability Testing

Infinity speakers have to undergo a rigid 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.

Competitively Tuned

Speakers are carefully tuned to assure high SPL and low distortion. This means that the usual specifications as well as individual speaker characteristics are considered when tuning for 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.
