You'll have to custom-mount tweeters or midrange speakers, which usually requires drilling holes and running new wires.

Legendary sound

Infinity's Kappa 10.11t 3/4" tweeters continue in the tradition of this legendary line of speakers, bringing you impressive sound quality. Once installed, these tweeters will bring out every nuance and detail in your favorite music tracks, making time spent in your car seem more like a concert than a commute.

Large soft dome tweeters

If you're looking for natural-sounding high frequencies, these edge-driven 3/4" soft dome tweeters are a great candidate for your system. The edge-driven" design creates a larger tweeter that handles more power and delivers smooth response way down into frequencies not covered by smaller "W"-shaped domes. You'll hear a more clearly defined soundstage where you can picture the placement of every instrument.

Infinity includes hardware for surface- or flush-mounting the tweeters, plus Starfish brackets that help you install the tweeters in many factory tweeter openings. The included external crossovers send the appropriate frequencies to the tweeters to protect them from damage.

Great for any system

These 2-ohm tweeters are sensitive enough that you can power them with an aftermarket stereo, but you'll get your best results feeding them plenty of power from an outboard amp — up to 50 watts RMS.

Product Highlights:

  • 3/4" soft dome tweeters
  • 2-ohm impedance
  • flush- and surface-mount hardware included
  • Starfish™ bracket for mounting in factory tweeter locations
  • outboard computer-optimized crossovers
  • power handling: 5-50 watts RMS (150 watts peak power)
  • frequency response: 3,500-35,000 Hz
  • sensitivity: 93 dB
  • flush-mount depth: 3/4"
  • warranty: 3 years
  • Our 60-day money-back guarantee

Features

Edge Driven: The 3/4" edge-driven tweeters use textile soft domes. An edge-driven tweeter has better dispersion characteristics and allows for a lower crossover frequency than typical tweeters of the same size, which improves imaging. The result is improved vocals and musical clarity.

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

  • I-Mount Tweeter Mounting System: 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 adapter and plastic locking nut. Once a cutout is made, the flush-mount adapter (with the tweeter installed) is 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:
    • Surface Mount (behind grille panel)
    • Flush Mount (behind grille panel)
    • Bottom Mount (to grille panel)
    • Flush Mount (in-dash location)

Excellent sound

Written By PickyAudiophile, Vancouver, WA on Tuesday, September 23, 2014

Crutchfield Customer Review (What's this?)

Great crossovers, so I don't have to worry about them over played. I added this pair to an existing Kappa system and mounted them high above me. I am just immersed in crystal clear sound. Love it.

Pros: Soft dome, so they aren't harsh. Great quality. Great sound.

Cons: Not the cheapest on your wallet!

awesome sound!

Good but not great

Written By bdubs504, New Orleans, LA on Sunday, February 16, 2014

Crutchfield Customer Review (What's this?)

I'm still getting used to these tweeters. They have good, clean, crisp sound, with little distortion, but their output/volume is low compared to other tweeters I've had. Tweeters, per se, are not supposed to be "loud," necessarily, but these are soft even for what I expected. Otherwise, I like the way they balance out the mids/lows, creating a fuller, more enjoyable sound stage.

Pros: Crisp, clean, clear

Cons: Low output

Satisfied Customer

Written By J.R.#3, Delano , CA on Monday, November 25, 2013

Crutchfield Customer Review (What's this?)

I am completely satisfied with this product. I have the pleasure of enjoying the performance promised by the product's manufacturers beyond my expectations and expect to never have to replace these tweeters any time soon unless the model to come of course promises better performance.

Pros: Size and applicability.

Cons: None

Infinity Kappa 10.11t tweeters

Written By Hal, Georgia on Sunday, November 17, 2013

Crutchfield Customer Review (What's this?)

I purchased these to upgrade my 2011 Chevy Silverado "post" mounted factory speakers, which were very shrill sounding. I was able to remove the old factory speakers and install the new ones using double sided tape. I am very pleased with the results. Extremely clean sounding. Gives a distinctive brightness that my system did not have. I can now hear sounds that I never knew were there. I changed out the door speakers with the 2ohm Infinity Kappa speakers. Coupled with a Clarion 4 channel class D compact amp and Clarion EQ from Crutchfield, All I can say is what a difference.

Pros: Very high quality. Comes with a variety of surface and flush mounting options. High quality crossover included.

Cons: A little pricey but well worth the money spent.

Written By Chad, Pa on Thursday, October 17, 2013

Crutchfield Customer Review (What's this?)

Overall very good sound install a lot of customizing but well worth money spent installed in stock location in 05 tuscon no cutting just mods to speaker mount on backside.

Pros: Exactly same size as originals

Cons: Mount altering and wiring ( had to use original plug from factory ones )

Written By JayR, Rochester.NY on Monday, May 13, 2013

Crutchfield Customer Review (What's this?)

I useed them to replace blown Jeep tweeters in 1998 Grand Cherokee. I used origional mounting plates and altered them a little for the Kappa's. Easy swap and sound better than expected. I'm happy

Pros: Small and shallow. Fit in a small recess. Cross over is also small and fit under dash trim.

I didn't end up using them and instead returned them due to ordering the wrong size, but returning was extremely easy and customer service is amazing!
