True 4 Ohm Impedance

These speakers are specially designed with true 4ohm technology. The impedance of these speakers are 3ohms, but when you pair them with thin factory wiring, the impedance will naturally rise up to a true 4ohms resulting in a maximum amount of power draw from your 4ohm rated factory receiver, aftermarket deck, or external amplifier. What it comes down to is efficiency. If you need a speaker that will get the most out of your current sound system, the Reference X series is for you.

Plus One Cone Technology

Each of the Reference X speakers features plus one woofer cone technology. This means the cone has been designed to be slightly larger than comparable speakers, giving you even more output on the same amount of power. This drastically increases the efficiency of the speaker, and also extends the frequency response even lower to give you that nice thump you’ve been looking for.

The Reference of Audio

Want an easy upgrade for your factory speakers without going over your budget? The Infinity Reference X Series is for you. Its engineered to bring your factory audio system to life, or to add clarity and depth to an aftermarket system. With innovative, patented technologies, and the kind of premium quality and construction that you would expect from the worlds top-selling premium car speaker brand, Infinity Reference X speakers will transform your listening experience into something amazing.


The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

Chevy Truck Speakers

Absolutely 1000% better than factory speakers. Sounds great. The sound is so much better.

Fantastic Quality

I bought these to replace my factory 4"x6" speakers. I was blown away at the sound quality from these speakers. For such a small pair of speakers, they put out an incredible amount of bass and have crystal clear mids and highs. They actually out-performed the JVC 6x9's that I bought, so I ended up replacing those with a pair of Infinity Kappas. I would highly recommend these, and any other Infinity product if you're looking for quality. If you're looking for an incredible subwoofer, I highly recommend the Infinity Reference 1262w or the Kappa 120.9w.

Nice!

Got these for my son's cavalier and they sound great! Coming off factory radio. May hook an amp later to see how they really sound.

Great speakers!

I just put 4 of these speakers in my old 90 Chevy truck. They sound great, way better than similar trucks with kicker or Sony speakers. Not much bass from 4x6 speakers, but these are surprisingly good. I highly recomend them.

Infinity speakers

These are great speaker and that is why I bought them. This is my second set for my Datsun Z. I want the best sound for my dollar so these are the best you can buy. Sonic E. Always has the best prices and I will continue to purchase my electronics from them.

Also, recomended by Sonic for my car.

Even in the tight position in between the top of the dash and windshield of a Corvette installation wasn't all that hard. The sound is so full and crisp with these speakers.

Great value and installation was easy.

The speakers are a great improvement over OEM. Installation was easy with optional installation template and wiring harness. Speaker support a lot more bass than OEM.

great deal

A major improvement

Best entry level speaker you can get.

I have been a professional installer for 15 years and have heard it all. You can't go wrong with anything hk, infinity and jbl are probably the best sounding entry level stuff you can get your hands on. Hands down sound better than the big brands. Pioneer, kenwood, jvc, kicker, Rockford, and Sony can't even compare. The only one even in the ballpark is alpine. For the extra $ they cost, I don't understand why anyone buys that crap you get at Walmart or whatever. Vr3, dual, boss, Pyle, planet audio.... Cmon people. Get it together already.
