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 125 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.

Tweeters very harsh.

Woofer puts out a decent amount of bass, but that tweeter is so bright and hissy. I've removed the highest frequencies using my head unit's equalizer. But I'm considering re-installing the stock (upgraded) tweeters, or returning the whole package.

Pros: Great bass

Cons: Tweeters sound hissy.

Chose these speakers after I installed 4 Infinity speakers in my 2000 F-150. I'm building a system for my 1967 Impala. These fit will fit in the rear deck and sail panels. These sound great.

2010 Camaro Infinity install

Jeff from Osceola, In. on 12/20/2018

2010 Chevrolet Camaro

Verified customer (What's this?)
Verified employee purchase (What's this?)

Installed these in my 2010 Camaro. Used stock head unit. Had to modify the stock installation location (top of rear deck) to make them work for me. Used Boston Acoustics tweeter mounts with Infinity tweeters. Made under deck mounts for 6x9's. Replaced stock BA amp with an Alpine PDR-F50. These speakers sound GREAT. Clarity is great, lows are good, highs not shrill but well defined. With a 10" sub and and amp and 6.5" Infinity Reference speakers in the doors my Camaro Rocks, sounds much better than stock Boston Acoustic system. JL Audio TWK 88 also helped in this setup. Highly recommend Infinity speakers and Crutchfield.

Pros: Super sound ,Great price (purchased on sale), Great customer service.

Cons:

100 times Bettter than the Factory Speakers!

Chip from Portland, ME on 12/10/2018

2011 Toyota Tacoma

Verified customer (What's this?)
Verified employee purchase (What's this?)

These speakers are beautiful sounding. No comparison with the factory Toyota speakers. This is the first time I have installed component speakers and the difference is remarkable. Finding a location for the crossover behind the door panel was a bit of a challenge, but was able to make it fit eventually without adding any extensions to the speaker wire.

Pros: Concert-hall sound.

Cons: Crossover is a little big and challenging to locate in the door panel.

Verified employee purchase (What's this?)

Installed in a 2006 Dodge Ram 2500 Quad cab. 6 x 9's easily fit in doors with no modifications. Tweeters installed in outer factory dash locations. Needed to make mounting plates that lowered speakers approximately 1/2" so tweeters could be angled slightly for better sound. Took my time and turned out great. Sound and separation of component speakers is awesome.

Specifications

Woofers

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.

Tweeters

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.

Dimensions:

  I-Mount Surface Mount I-Mount Flush Mount Starfish Bottom Mount Starfish Surface Mount Starfish Flush Mount Starfish Flush Mount (below mounting surface)
Mounting Height 0.854" 0.65" 0.0" 0.857" 0.386" 0.286"
Depth screw depth 0.786" 0.930" screw depth 0.471" 0.571"
Frame Diameter 1.474" 1.838" 3.036" 2.440" 2.330" 2.330"
Cutout Diameter N/A 1.581" N/A N/A 1.504" 1.257"

Crossovers

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 0.31" wide. There are four mounting holes in each crossover.

Dimensions:

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

Specifications

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.
