About the Infinity Reference REF507CF

Dave Delamere

A modern classic

Just as they were throughout my 16 years as a Crutchfield Advisor, Infinity's Reference Series speakers remain a popular choice for upgrading from factory speakers. The REF507CF 5-1/4" component speaker system follows that Infinity heritage by offering the killer combo of high efficiency and superb sound.

The external crossovers direct the right frequencies to the tweeter and woofer.

Edge-driven dome tweeters

With this component system, you'll gain exceptional clarity and imaging, thanks to separate 3/4" edge-driven textile dome tweeters that subdue any harshness in the high-frequency range. Infinity includes external crossovers with push-button tweeter attenuation for a "brightness" quick fix.

Bigger woofers

Reference Series speakers deliver powerful sound every mile you drive, thanks to oversized polypropylene woofer cones with durable hi-roll rubber surrounds. The cones move more air than speakers of similar size, adding plenty of punch to the speaker's impressive performance.

Excellent power-handling

These speakers will blossom when powered by an external amplifier, but they're also sensitive enough to be a good match for a factory or aftermarket stereo. Plus, Infinity has come up with a safe way to get a little more power out of your system — these 3-ohm speakers work in combination with the speaker wire in your car so your car stereo sees a true 4-ohm impedance.

Note: woofer grilles are not included; these speakers are designed to work behind factory grilles or panels in most applications.
