Our take on the Infinity Kappa 62.9i

Infinity built the latest Kappa speakers with improved technology and high-end materials to provide you with outstanding sound reproduction. The Kappa 62.9i 6-3/4" speakers feature light, but stiff woven glass-fiber woofer cones that won't flex or distort. The Plus One design offers a larger surface area for improved low-frequency output and efficiency, while longer voice coils produce tighter, snappier bass. Large magnets keep the woofers running cooler by placing more steel close to the voice coils to act as a heat sink.

Infinity uses the same Metal Matrix Diaphragm tweeter found in many of their popular home speakers, so you'll hear the music the way it was recorded with minimal coloration or distortion. The dome tweeters pivot, allowing you to adjust them for better stereo imaging.

The computer-optimized outboard crossover networks employ audiophile-grade components to separate highs and lows, so that the woofer and tweeter work together perfectly. Pre-wired crossovers eliminate a time-consuming step in your installation, and terminals at the end of the crossover wires screw directly to the speakers, leaving no chance for incorrect wiring.

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.

Installation Note: These Infinity speakers do not include screws or speed clips. You may be able to use the factory screws to install them, but it's always a good idea to have an assortment of self-tapping screws (5/8" to 1") and speed-clips on hand. These speakers don't use a standard 6-1/2" speaker bolt pattern — you'll have to drill new screw holes in either your vehicle or the included bracket in order to mount them in 6-1/2" speaker openings.

Important Note: You should use an outboard amplifier to power these speakers.

Highlights:

  • 2-way 6-3/4" speakers (pair)
  • fit 6-1/2" openings (with modification)
  • True Four Ohm Impedance technology: speaker's 2-ohm impedance combines with speaker wire impedance for a 4-ohm load
  • Plus One® woven-glass-fiber woofer cone with hi-roll rubber surround
  • 1" rotating UniPivot, edge-driven M.M.D.® dome tweeter
  • computer-optimized outboard crossover with tweeter level control
  • direct-connect crossover dongle
  • power range: 2-75 watts RMS (225 watts peak power)
  • frequency response: 45-25,000 Hz
  • sensitivity: 95 dB
  • top-mount depth: 2-3/8"
  • warranty: 3 years
  • Our 60-day money-back guarantee

Features

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

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

Woofer Size: These speakers are marketed as 6-1/2"; 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 need be used. If drilling in the car is not an option, the flange on the included metal bracket is wide enough to accommodate new holes being drilled; either in a standard 6-1/2" three hole pattern or a Ford non-symmetric four hole pattern. When using the bracket the depth becomes 2.136" and the mounting height becomes 1.024".

Edge Driven MMD Dome Tweeters: Each speaker has an Edge-driven MMD (Metal Matrix Diaphragm) dome tweeter. The benefit is increased power handling and reduced distortion at high output. This technology also allows for better integration with the mid/woofer. The tweeter has an adjustable output level, +0 dB (flat) and -3 dB.

UniPivot Tweeter: The tweeter is angled and can be rotated about 270° after installation. This allows you to direct the tweeters toward the listeners, very useful for speakers mounted low in a door.

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 your speaker wire provides 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.

Crossovers: Kappa speakers include computer-optimized, voice-matched crossovers, using audiophile quality air core inductors and polypropylene capacitors. The crossover slope is 12 dB/octave.

Crossover Connections: Each crossover is connected to the speaker by a 6" wire. The input terminals are set screws that will accept up to 10 gauge bare wire.

Crossover Dimensions:

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

Intermount III: Infinity's Intermount III mounting system allows the 62.9i speakers to fit a variety of 6-1/2" (with modification) and 6-3/4" applications. Two adapter rings are included for each speaker.

I replaced my stock Mercedes Speakers (non-Bose) with these Infinity Kappa and OMG! I still cannot get over how fantastic they sound! My Crutchfield Advisor told me I would notice, and he was not kidding. The top-end clarity and bass are clean and tight. Highly, highly recommended.

I have finally replaced rear pair from stock speakers of '05 Acura RSX with Infinity Kappa 62.9i. Crutchfield deemed that they would not fit (not even as modified fit), but the installer was able to fit them just fine using adapter bracket. No amp, just four 62.9i speakers on my car now. I was unsure was about needing amp to bring out the true potential of these speakers, but once I started playing Miles Davis' Kind of Blue, I was completely blown away. It was so crisp and powerful, I thought the instrument was playing from where my speakers were. This may not be a good idea if you are too distracted by music (and forgets to pay attention to the road), otherwise, this is truly amazing product. Great speakers are not about pumping out the most bass, but to reproduce each and every note as faithfully as possible. I think this speaker nailed it.

I bought these for my 2011 Kia Soul and replaced all 4 door speakers. The factory stuff is basically just made out of foam...literally. The bass is wayyy deeper and the highs are much crisper.

Personally, I need more bass so I'll be purchasing a JL sub too but these speakers are a GREAT step in the right direction.

Infinity Kappa 62.9i

Written By Jarrod, Albuquerque, New Mexico on Monday, October 26, 2009
 
I bought these speakers to replace my factory infinity speakers in a 1997 Dodge Dakota. I have to say that these are perfect replacements especially for my system. They fit perfect and sound awesome with the factory infinity gold amplifier and factory deck. Next project will be to replace the rear speakers with infinity kappas, and then the deck. Great product definitely buy.

Sounds good just powered by the deck, but if you put an amp on them they will sing loud and clear without distortion

Hello, every Crutchfield reader. I have purchase thIs infinity Kappa for a Toyota Corolla 2009. 6.5 on the front door panel-6X9 at the rear.(they do need an extra mounting plate -a larger hole there). This speakers are the best on the market this days. I have an amp ready for them but amazingly this bad boys are loud ,this factory stereo on this car have plenty of power to run this baby's. on the other hand at the auxiliary input I'm using a Sony MP3 -- NWZ-A728 it has a equalizer that almost double the sound

Awesome with an amp

Written By Brian, Long Valley, NJ on Monday, June 23, 2008
 
short bottom line conclusion:
YOU MUST PURCHASE AN AMP TO DO JUSTICE/ HEAR THE AWESOMENESS OF THESE SPEAKERS

I first installed these speakers without an amp. I bought bass blockers as a remedy for the "popping" sound I heard from heavy bass. This solved that issue but then since these speakers are 2 ohm speakers, they drew too much power from the head unit and it started to heat up and clip.

Without an amp, these speakers sound subpar.

I decided to get the Profile AP400 amp.
best decision for these speakers. they sounded awesome
-allowed them to play louder, clearer, produced better bass etc.
- really allowed these speakers to play to their full potential

REALLY! A few extra bucks. You won't believe the sound improvement. I have the downgrade of this line of speaker in another car. I am going to take them out and replace them with theses because they sound that good.
