Edge-driven dome tweeters

With this component system, you'll gain exceptional clarity and imaging, thanks to separate 3/4" edge-driven textile dome tweeters that subdue any harshness in the high-frequency range. Infinity includes external crossovers that give you push-button tweeter attenuation for a "brightness" quick fix.

Bigger woofers

The Reference Series polypropylene woofer with its durable hi-roll rubber surround ensures you'll enjoy powerful sound every mile you drive. Its oversized cone moves more air than other speakers of similar size, adding plenty of punch to the speaker's impressive performance.

Bring on the power

You can power these speakers with up to 90 watts of RMS power — they'll work well with an external amplifier, but they're also a good match for a factory radio or aftermarket stereo. Plus, these 3-ohm speakers combine with the speaker wire in your vehicle so your car stereo sees actual 4-ohm impedance, so you get a little more volume out of your system.

Product Research



Plus One+ Woofer Cones: Each speaker uses a larger cone 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.

Mounting: Without an adapter, the 6530cx woofers fit standard 6-3/4" applications. Given their required cutout, they will also fit 6-1/2" applications without an adapter, but new screw holes must be drilled. Using the included adapter brackets they can be mounted in a wide variety of 6-1/2" and 6-3/4" applications, without any modification.


Material: Each tweeter features a 3/4" edge-driven textile dome for smooth, accurate highs.

Mounting: The I-Mount tweeter mounting system and Starfish mounting brackets give you several different ways to mount the tweeters:

  • I-Mount: The tweeters can be surface- or flush-mounted with Infinity's innovative I-Mount system:
    • Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
    • Flush Mount: Flush mounting is made easy through the use of the threaded flush-mount housing and plastic locking nut. Once a cutout is made, the tweeter is installed in the flush-mount adapter, then into the flush mount housing and inserted into the hole. The large plastic locking nut is threaded onto the adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging.
  • Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the grilles:
    • Bottom Mount: Once the Starfish bracket is trimmed, it is secured to the underside of the grille panel. The tweeter must be inserted into the bracket and locked into place before the bracket is mounted.
    • Surface Mount: Once the Starfish bracket is trimmed, it is screwed to the top of the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Flush Mount: There are two sets of tabs to flush mount the tweeter in the Starfish bracket, yielding different mounting dimensions. The upper tabs mount the tweeter completely below the opening and are glued in place. The lower mounting tabs are screwed in place and result in a mounting height just under a half inch. Once the bracket is mounted, the tweeter is inserted into the bracket and locked into place.

Cutout Diameter N/A 1.581" N/A N/A 1.504" 1.257"


Selectable Tweeter Output Level: Each 2-way crossover allows you to select the tweeter output level according to system requirements and personal preference; the tweeter level can be set to +3 dB or 0 dB.

Connections: The crossover inputs and outputs are screw terminals; they will accommodate bare wire or spade connectors up to 0.3" wide. There are four mounting holes in each crossover.


  • Width: 4"
  • Height: 1-1/8"
  • Depth: 3-1/4" (plus wire)


High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.

Customer Q&A

Crutchfield asked: Why did you buy this?
Best option for the money and my application using the factory head unit [ Christopher  Feb 01, 2019 ]
Good deal [ John  Jan 12, 2019 ]
If was in the market to upgrade my front speakers in my 91 Camaro. I was worried about it complimenting my current system. (Pioneer head unit, JL Amps and subs) I was wanting to buy JL audio to keep my equipment the same brand. The Infinity Reference just sounds more crisp and clear. (C2-650) The sensitivity is higher at 93db and the higher wattage is a plus too. I love my JL Audio but I have to buy what sounds best and is in my price range! PS-Drummer was awesome advisor! [ Chris 1962  Jan 02, 2019 ]
Listed as a top seller with great reviews and great specifications (judging from the help tooltips provided). Also a great price and amazing customer service. [ Fernando  Nov 27, 2018 ]
Sale price [ saul  Nov 27, 2018 ]
Value. Price along with performance [ Prmdc1  Nov 26, 2018 ]

50% off couldn't pass it up [ Justin  Nov 25, 2018 ]
great sale price [ William  Nov 25, 2018 ]
Truck getting update with new paint just replacing old set of same design by Infinity in my 2005 Ranger , they have been in my truck since 2005 have great sound and have well used excellent performance [ Lacy  Nov 25, 2018 ]
Looking for good component speaker system at good price. These were 50% off. [ JOHN H  Nov 24, 2018 ]
My factory speakers aren't putting out the sound I need in my truck and I had the Infinity reference speakers in my old truck so I thought why not try them again. I also bought a set of two way Infinity's for the rear doors. I hate all new music all I listen to is 60-70 classic rock, blues, and a lot of dead guy's. These speakers will get the sound I need on the CHEAP! [ GLEN  Nov 23, 2018 ]
I like the specs and it is a good brand! [ Donald  Nov 17, 2018 ]
These are an upgrade to my daughter's car. I chose this component set for the front doors and a matching 2-way set for the rear doors. The impedance and sensitivity should provide a good match to the factory head. [ Jeffrey  Oct 18, 2018 ]
Past experience with Infinity component speakers were positive. Sound quality has been very satisfying, price point is a bonus. [ Randy56  Aug 13, 2018 ]
Kappa's with the larger magnet would not fit the back doors (and clear widow actuator) of my 4door Silverado. These just' clear and compliment the system nicely. [ MARVIN  Jul 13, 2018 ]
came recommended [ MANDEEP  Jun 29, 2018 ]
Because of the low impedance technology. If it can save me from buying an amplifier right now, that was the selling point [ Elijah  Jun 19, 2018 ]
reviews [ anthony  May 30, 2018 ]
