Our take on the Infinity Kappa 60.11cs

by John Pollard
Infinity

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Legendary sound

Infinity's Kappa Series 60.11cs 6-3/4" component speakers continue in the tradition of this legendary line of speakers, offering rugged construction and impressive sound quality. Once installed, this system 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, Infinity uses edge-driven 3/4" soft dome tweeters in this system. The "edge-driven" design results in a larger tweeter that handles more power and delivers smooth response way down into midrange 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.

Glass fiber woofer with Plus One+ technology

If you like bass, the Kappa glass fiber woofer holds its shape when the power's cranked up, so you still get punchy and defined bass. Glass fiber weighs less than traditional materials, so you don't need a ton of power to drive this woofer. Infinity's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you more surface area than with most comparable speakers. A bigger cone means more bass to complement the superior high-frequency response. The included external crossovers send the appropriate frequencies to the tweeters and woofers.

Great for any system

These 2-ohm speakers 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 90 watts RMS. Grilles are included.

Note: Infinity describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Woofers
Tweeters
Crossovers

Woofers

Plus One Woofer Cones: The Plus One woofer cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and a significant increase in efficiency.

Formed Glass Fiber Woofer Cones: The formed glass fiber cone material is very light and extremely stiff, minimizing flex. This results in very low distortion and improved clarity.

iCGM frames: The Kappa series speaker baskets are made of composite Injected Carbon Glass Matrix (iCGM). iCGM is lighter and stronger than stamped steel; it retains its shape, even when mounted on uneven surfaces (common in car mounting locations), plus offers exceptional damping of any resonances.

Woofer Size: This component set is marketed as having 6-1/2" woofers; they will fit in standard 6-1/2" speaker openings, but do not use the standard 6-1/2" speaker bolt pattern. In order to install them in standard 6-1/2" speaker openings you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6-1/2" mounting holes and the Ford non-symmetric four hole pattern. When using the brackets the depth becomes 1.885" and the mounting height becomes 0.773".

Terminals: The woofers' input terminals are gold-plated set screws that will accept up to 12 gauge bare wire.

High-Output Design: The high output 2-ohm voice coil design compensates for the high in-line resistance of small gauge factory wiring and extracts every watt from factory receivers, increasing overall system output and efficiency (relative to 4 ohm speakers). The speaker's 2.0-ohm impedance combined with the impedance of the factory speaker wire presents a true 4-ohm load to your connected headunit or amplifier. The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers, designed to power a 2-ohm load.

Tweeters

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): Once the Starfish bracket is trimmed, it is screwed to the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Flush Mount (behind grille panel): Once the Starfish bracket is trimmed, it is dropped into the cutout in the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Bottom Mount (to grille panel): 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.
    • Flush Mount (in-dash location): Once the Starfish bracket is trimmed, it is dropped into the cutout in the dash. Then, the tweeter is inserted into the bracket and locked into place.

Tweeter Mounting Dimensions:

  I-Mount Surface Mount I-Mount Flush Mount Starfish Surface Mount (behind grille panel) Starfish Flush Mount (behind grille panel) Starfish Bottom Mount (to grille panel) Starfish Flush Mount (in-dash location)
Mounting Height 0.936" 0.685" 0.943" 0.423" 0.0" 0.423"
Depth 0.372" (screw depth) 0.778" 0.331" (screw depth) 0.586" 1.077" 0.586"
Frame Diameter 1.615" 2.218" 1.655" 2.610" 3.247" 2.475"
Cutout Diameter N/A 1.894" N/A 1.655" N/A 1.655"

Crossovers

Crossovers: The crossovers use low-loss air core inductors, low-hysteresis polypropylene capacitors, and high-quality resistors. Each crossover has a tweeter output level switch; choose between flat and +3dB.

Connections: Each crossover has set screw input and output terminals that will accept up to 10 gauge bare wire.

Crossover Dimensions:

  • Length: 3-3/16"
  • Width: 4"
  • Height: 1-3/8"

Power Handling: Although Infinity lists the RMS power handling as 90 watts, they also list the recommended power range as 5-200 watts RMS. We've opted to list the more conservative 90 watt RMS figure on the specifications page.

Ahhh...so much better

Written By Nancy with a 2014 Subaru Outback, Columbia, MO on Saturday, April 26, 2014
Crutchfield Customer Review (What's this?)
 
It is an amazing upgrade from stock speakers in a 2014 Subaru Outback from Harman Kardon to an aftermarket Infinity speaker made by same company. I did need to add an aftermarket amp to create a good sound in these speakers. The Subaru standard system was poorly designed by Harman Kardon in that almost all the sound was blasting at you from the tweeters designed into the dash and reflecting from the front window. It was unbearable and became so bad I had to keep the volume barely audible and moved to front to back fade 20% front/80% back. Although the sound was good with this speaker set alone...the sound did not round out until I added the component speakers bought on Crutchfield from Infinity. The pricing on the speakers from Crutchfield was much better than at the local shop. Thanks Crutchfield.
Pros:
They are a good speaker.
Cons:
They don't create a WOW factor and additional amp is needed. They have slight distortion at high volume. Best not to really crank it, but will be plenty loud for some head banging on 60-70% volume. (I had gotten use to a THX system in my prior car...no much will compare).

F-150

Written By Kevin, Washington on Sunday, December 15, 2013
Crutchfield Customer Review (What's this?)
 
Phenomenal difference! I had some 6x8 coax infinitys before switching to these components and the time and effort was well worth it. The tweeters are super clear. They are a little brighter than a silk dome, but cut through the road/ambient noise with ease. The mids are just as impressive, I can't say enough about these speakers, but there are some cons. This is the first time that I've purchased speakers that didn't at least come with wiring, there were no instructions either. The mounting options for the tweeters was a disappointment as well. I originally wanted to mount them in the sail panel to keep them close to shoulder level, but the only basket with a trim ring would have required a huge hole to be cut in the panel, and then the tweeter would be sticking out almost an inch. Not a good look in my opinion. I ended up using the stock location and attaching one of the baskets to the back of the door panel. Looks and sounds great, so I guess it's o.k. in the end.
Pros:
Very clear, high quality.
Cons:
No instructions/wiring, limited install options.

Potent Speakers Make My Car Fun to Drive Again

Written By Danster, Southern California on Tuesday, October 01, 2013
Crutchfield Customer Review (What's this?)
 
I replaced the tired and buzzy OEM speakers on my venerable 1999 Saab 9-5 SE with these beautiful speakers. The Infinity Kappa 60.11cs were a logical choice for replacing the stock Saab speakers, which interestingly enough were also manufactured by Harman-Kardon nearly 15 years ago. Sticking with the family pedigree enabled me to find those rare 2 ohm impedance speakers that were specified for my car's AS3 sound system. (Before starting this project, I decided to keep the stock H-K electronics and not add any aftermarket amplifiers.) The evolution in product design and quality is very noticeable. Be advised that the upgrade is not a simple pull and plug, some minor car modifications are required for the installation. For the front doors, I had to use a Dremel grinder to shave the inside ribs of the OEM mounts, then drill four new screw holes, to accept the 6.5" speakers. For the tweeters in the front dash, I used the supplied I-mount "starfish" fastened underneath a fabricated MDF adapter plate, so that the domes would not interfere with the stock speaker covers. Connections to the auto harness were simplified by using Metra 72-6512 connectors; no harness cuts or splices were required. The improvement in sound quality is remarkable. I mostly listen to jazz; the vocal phrasings, string and wind instruments are very crisp, articulate and well-blended. I like these new speakers so much that I'll probably take them with me when I sell my car several years down the road!
Pros:
Solid construction, fine engineering and design, outstanding sound. Excellent phrasing. Two ohm impedance design plays well with my stock stereo. The kit includes a generous variety of mounting hardware.
Cons:
Wish that the starfish would have spanned larger openings, so that I wouldn't have to fabricate a custom mounting plate.

Great upgrade!!

I bought these when they went on sale and couldn't be happier! Replaced the stock component speakers in my Crossfire and even without an amp running to them these sound amazing! They're efficient enough to produce fantastic sound at low RMS but hit them with 60-90 watts and get ready for bliss in your ears!
Pros:
Great sound even at low RMS Superb sound with a dedicated amp Great build quality
Cons:
None

I purchased these speakers to replace the factory Bose speakers. The sound is great. It took some adjusting to get the sound just right but once it was adjusted, I could not have made a better choice for the money. I purchased the amp, wiring and also a pair of Kappa 62's. for the rear. I was familiar with the 62's as I installed in a previous truck.. If this is your choice, you won't be disappointed.
