Our take on the Infinity Reference X REF-5002ix

by John Pollard
Infinity

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

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.

 REF-5002ix 5-1/4

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.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

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.

Written By Hector, Dallas, TX on Friday, July 26, 2013
Crutchfield Customer Review (What's this?)
 
Installed these speaker on a 2003 Jeep Wrangler as the bar speakers on the back. Installations was easy and with no problems, the speakers looks really good. Sounds is excellent for the size of the speakers. Wish I had some more bass, you can fix these if you get a sub woofer ( my next purchase). Will recommend these speakers anytime. Great highs and mid range Ok bass.
Pros:
Great look Great mid range and highs Good price
Cons:
OK bass but not bad

Marine application, though internally in a cabin, so not subject to the elements. Driving them using a NuForce Dia amp off of a TV. Wish there was a little more bass response, but generally happy. Will be adding a powered sub and all should be good.

Exceeded my expectations

Written By François, Montreal, Canada on Sunday, January 20, 2013
 
Simply... Wow! Installed in my BMW-3, I was crossing my fingers for them to be "at least ok". Although a sub would not be a total waste, the small 5-1/4 speakers have plenty of punch. But the most impressive is the sound softness and clarity. Not at all worried about potential listening fatigue. Unless you plan to throw $300-$400 on other higher-end models, go for these Infinity.
Pros:
Great value, sound softness and clarity
Cons:
None

B&W in your car

Crutchfield Customer Review (What's this?)
 
Really fine speakers, coming from an audiophile, well built with very clear audio response. These are both economical and compact for tricky installations. I added a sub-woofer and amp, now they exceed any expectations I had in mind for the units. I liked the load of accessries and mounting hardware and the easy to read instructions.
Pros:
Cost, performance and compact size.
Cons:
None
