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

Infinity Reference REF687F 2-way 6"x8" car speakers

Designed to work behind factory grilles, these Infinity speakers can liven up your music.

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.

Product Research

Features

Plus One+ Woofer Cones: Each speaker uses a cone larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and an increase in efficiency.

Angled Tweeter: The tweeters are mounted at an angle (fixed), so they can be directed toward the listeners to improve imaging.

Tweeter Level Control: A switch on the front of the tweeter allows you to boost the tweeter output to +3dB, useful if the speakers are mounted low in a door where high frequencies are easily absorbed.

High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers.

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
