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.

Just Ok

The speaker were a drop in fit for my wife's 2012 Lexus CT200h. The sound was ok, obliviously they are underpowered because I don't have an amp running them. What I can say is that the highs are brighter but that's about it. They were an improvement from the stock speakers just not as much I was hoping for.
