Infinity Primus 12" Car Subwoofer
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.
