Infinity Reference X REF-5002ix
5-1/4" 2-way car speakers
Our take on the Infinity Reference X REF-5002ix by Crutchfield's John Pollard
Designed for more clarity
Do you want to hear the details you've been missing in your car's sound system? You'll enjoy exceptional clarity from Infinity's Reference X Series REF-5002ix 5-1/4" speakers. Infinity's UniPivot design allows you to aim each textile, edge-driven tweeter toward your ears, so you enjoy excellent stereo imaging even if the speakers are mounted way down low in your doors. Each tweeter features a level control switch so you can boost the brightness to your taste.
Larger woofer for more bass
The REF-5002ix appeals to bassheads too, with tough polypropylene woofers and durable hi-roll rubber surrounds that deliver strong low-frequency performance. Each Plus One+ woofer sports a significantly larger cone than speakers of similar size, adding plenty of punch to the speaker's smooth and accurate highs.
Great for any power supply
You can power these speakers with up to 45 watts of RMS power — they'll work great with an external amplifier, but they're also sensitive enough to be a good match for a factory or aftermarket stereo. Plus, Infinity comes up with a safe way to get a little more power out of your system — these 3-ohm speakers combine with the speaker wire in your car so your car stereo sees actual 4-ohm impedance. Grilles are included along with Infinity logo badges that can be attached to your factory grilles.
Great sound and look would buy again

Plus One+ Woofer Cones: Each speaker uses a cone significantly 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 increased efficiency.
Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.
Textile Dome Tweeters (UniPivot Design): Each speaker uses an edge-driven textile dome tweeter for smooth, accurate highs. The UniPivot design mounts the tweeter at an angle and pivots, so the tweeter can be pointed at the listeners, optimizing the stereo image for a more uniform response. The tweeter housing can be turned approximately 315 degrees.
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.
True Four Ohm Impedance Technology: The speaker's 3-ohm impedance combined with the impedance of your speaker wire provides a true 4-ohm load to your connected head unit or amplifier.
Power Handling: Although Infinity rates the 5002ix speakers at 45 watts RMS (continuous average), they also recommend amplifiers with a power rating from 5 to 75 watts RMS.
