Description

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 REF687F 6″x8″ 2-way car speakers follow that Infinity heritage by offering the killer combo of high efficiency and superb sound.

Infinity’s famous ingredients

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 other speakers of similar size, adding plenty of punch to the speaker’s impressive performance. The 1″ textile balanced-dome tweeters deliver clear and smooth highs, for a sound that’s definitively Infinity. You can compensate for a less-than-ideal lower door location by raising the tweeter level by 3 dB to get more out of those higher frequencies.

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: grilles are not included; these speakers are designed to fit behind the factory grilles or panels in for most applications.
