Infinity Reference X REF-3002cfx

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-3002cfx 3-1/2" speakers. Infinity uses PEI balanced dome tweeters to bring out all the details in your music without sounding harsh.

Larger woofer for fuller sound

The REF-3002cfx features tough polypropylene woofers and durable hi-roll rubber surrounds that deliver strong 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 25 watts of RMS power — they'll work great with an external amplifier, but they're also 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 vehicle so your car stereo sees actual 4-ohm impedance. Grilles are not included — factory grilles are appropriate for most installations.

These speakers are really a pain to replace but once done it will be totally worth it. The stock speaker had no high end and these are a good upgrade

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 an increase in 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.

Tweeter: Each speaker has a balanced dome tweeter. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter.

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 3002cfx speakers at 25 watts RMS (continuous average), they also recommend amplifiers with a power rating from 5 to 50 watts RMS.

If you're running them straight from head unit, you should be able to adjust the internal crossover to keep bass from entering those speakers [ MELVIN  Oct 13, 2016 ]
No they dont [ Matthew  Oct 13, 2016 ]
Yes, Crutchfield didn't tell me they did, but now that the tweeter in one is blown, they tell me I should have used bass blockers with them. :-( [ KENNETH  Oct 12, 2016 ]
