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.
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.
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.
