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.

- Diameter : 12 Inch
- Sensitivity : 91 dB
- Impedance : 4 Ohm
- Frequency Response : 35-200 Hz
- Peak Power Handling : 1200 Watts
- Top Mount Depth : 5-15/16 Inches
- Bottom Mount Depth : 6-7/16 Inches
- Number of Voice Coils : Single
- Suggested Sealed Box Volume : 1.4 Cubic ft.
- Suggested Ported Box Volume : 1.6 Cubic ft.

Features:
- Sealed Box Volume: 1.4 ft³; a sealed enclosure design gives the smoothest response with increased energy at the lowest frequencies
- Ported Box Volume: 1.6 ft³ with one 2.95" diameter x 4" long port (tuned to 34 Hz); Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier
- Free-Air: The woofer can also be mounted in free air to a baffle board (infinite baffle, no enclosure). When mounted in free air, the power handling is reduced by half (to 150 watts RMS).
- Band-Pass: Infinity also recommends a prefabricated band-pass enclosure, but no volume specifications are listed in the manual. Band-pass enclosures often provide the most output available from any amplifier and subwoofer combination, but at the expense of sonic accuracy.
