Verdict

Thanks to half-inch balanced textile dome tweeters that bring out all the details in your music without coming across as harsh, the Infinity Reference REF-6422cfx represents a smart choice in the aforementioned bang-for-the-buck 4×6-inch category. What’s more, the speakers’ tough polypropylene woofer with its durable hi-roll rubber surround delivers astonishingly strong performance from a speaker of this size.

Pros

  • Plays music boldly and cleanly
  • Extracts full power from any amplifier or car stereo due to low impedance
  • Plus One woofers are 30-percent larger than other speakers in same size category

Cons

  • Takes some extra effort to tune a head unit to the speaker for the optimum result
  • Depending on configuration/setup, sound can appear to have more treble than bass
  • Some owners complain of slight rattles

Overview

We can’t talk about speakers – whether for the car or the home – without mentioning the name Infinity. Whether it’s the company’s value-laden Primus floorstanding towers that grace a plethora of home theater and two-channel/hi fi systems everywhere or one of its multitude of subwoofers, speakers and amps packing the trunks of mobile soundoff competitors, the brand is instantly recognized by enthusiasts the world over.

Into this foray has come to the Reference REF-6422cfx car speakers, sporting sleek, serious looks, and forward-thinking features such as edge-driven textile tweeters and Plus One woofer cones. The three (3)-ohm impedance rating, meanwhile, results in a high sensitivity spec of 92 dB.

As the 99carstereo.com Bang for the Buck 4″x6″ pick, Infinity’s REF-6422cfx offers woofer cones significantly larger than other speaker models of the same size, greater bass output, increased efficiency, balanced dome tweeters, clearer and richer sound and adapters that allow the speakers to fit many top-mounted standard 4×6-inch and metric 4×6-inch applications.

There isn’t one perfect speaker to end all speakers, as it seemingly is with any consumer product, but the Infinity REF-6422 represents a value proposition with a lot of installation creativity potential.

Review

Infinity’s REF-6422cfx is a 4×6-inch two-way loudspeaker that allows you to get closer to your music in ways you never thought possible. Each Plus One woofer boasts a significantly larger cone than speakers of similar size, resulting in a boatload of “punch” that complements the speaker’s smooth and tactile high-frequency delivery.

The speakers can handle 45 watts RMS (continuous) of power, and while they will work just fine with an external amplifier, they also happen to be a good companion for a factory or even aftermarket head unit on its own. Further, the three (3)-ohm impedance of the 6422 ensures that the speaker wire in your vehicle “sees” an actual four (4)-ohm impedance – this means more volume can be squeezed out of your system.

Grilles are not included, but most vehicles’ factory grilles will work just fine for general installations.

Included in the box are two standard 4×6 mounting adapters, eight machine screws (to attach the speakers to mounting brackets), eight nuts, two adhesive-backed foam gasket strips, an instruction manual and a template on the actual box.
