75W peak power handling (25W RMS)

The REF-3002cfx 3-1/2-inch (87-millimeter) coaxial speakers handle a full 75 wattsW peak power and a very respectable 25 watts RMS. This power rating ensures that you’re choosing speakers that will work well with a varied range of products, whether you’re installing them as an upgrade to a factory-installed sound system or connecting them to an aftermarket head unit or dedicated power amplifier. (If you’re planning your audio-system layout, the recommended power for REF-3002cfx speakers is anywhere between 5 and 200 watts.)

Plus One woofer cones

The Plus One woofer cone is a patented technology designed to deliver more diaphragm area than other speakers in the same size class. Because of their increased cone area, Plus One cones move more air, thus playing louder and overcoming the road noise inherent in a car. By radiating more air more effectively, the speaker performs as if it were a larger model usually associated with better low frequency response. The end result is bigger and better sound.

Vented voice coil

Infinity REF-3002cfx speakers feature vented voice coils through their magnet and frame assemblies. Keeping the voice coils cool leads to greater power handling and increased reliability, and helps eliminate the power compression that can cause distortion. It’s just another way that Infinity engineers ensure that you’ll enjoy these speakers for the long haul.

High sensitivity (91dB@2.83V/1m)

These numbers mean simply great performance overall with even very moderate power driving the speakers. It makes the REF-3002cfx speakers an ideal replacement for factory-installed speakers as well as for any aftermarket installation.
