Best In Class Bass Performance
Price-leading classic Infinity styling subwoofer, the Alpha 121W subwoofer gives low-frequency punch with professional Infinity design to your vehicle. The subwoofer is built with lightweight yet stiff polypropylene cone and hi-roll rubber surround to reproduce accurate bass with less distortion. The shallow mount depth design allows it to fit into even smaller spaces and pre-fabricated sealed or ported enclosures as well.
Highest Grade Materials, Super Reliability
Polypropylene cones and rubber surrounds provide long lasting performance free from unwanted distortion and unwanted coloration. It's all about the bass!
Shallow Mount Depth Design
The Alpha 121W was engineered to deliver high excursion but a shallow mounting depth allowing them to fit into tight spaces and a broad variety of pre-fabricated sealed or ported enclosures.
HARMAN Standard Reliability Testing
Every Infinity speaker undergoes 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
The Alpha 121W was tuned to deliver superior low frequency extension, SPL and performance by way of Infinity's custom tuning process.
Infinity at an Affordable Price
Infinity is one of the most innovative and legendary companies in audio. Infinity is one of the top-selling car speaker brands in the world û obviously, this is no coincidence.
