You probably spend more time listening to music in your car than in your home. Why not enjoy home speaker sound quality when you're on the road?

Infinity Reference 6812cf 5"x7"/6"x8" speakers feature silk dome tweeters that would be right at home in your living room speakers. These sweet-sounding domes deliver crisp, clear response, yet won't fatigue the ears. The tweeters pivot, so you can direct the highs for a well-balanced stereo "sweet spot" — just like sitting in your favorite listening spot at home.

Infinity designed their Plus One+ woofers with more surface area than other 5"x7"/6"x8" speakers, for higher efficiency and improved bass output. The hi-roll rubber surround allows plenty of cone movement in the non-resonant powder-coated steel basket.

Settle into the driver's seat and make the most of your daily drive time with the exceptional sound of Infinity Reference speakers. Grilles are not included. (Factory grilles are appropriate for most installations.)

The best 6x8 speakers the world will ever see (unfortunately)

Written By CrunchyCookie, Palo Alto, CA on Tuesday, February 08, 2011

What's a guy doing reviewing 2005-year speakers in 2011? Simple: Infinity made
me buy these. I discovered that in 2006, Infinity made the decision to lower the
impedance of all their speakers from 4 ohms to 2 -- a total head-scratcher
considering the entire car stereo industry has long set the standard at 4 ohms.
Infinity claims that its speakers are safe to use with any stereo, but the
owner's manual of my Pioneer deck makes an explicit contradiction, instructing
NOT to hook up speakers with less than 4 ohms. I decided to place more faith in
Pioneer's words, so instead of buying Infinity's current model 6x8s (the
6832CF), I had to scrounge around the Internets for crappy used copies of these
long-forgotten units. Result: an unwanted compromise from my perspective and
lost revenue from Infinity's. Lose-Lose.

But I'm happy with what I've got. I've known for years that Infinity speakers
have the best sound around (though Pioneer and Polk come close), and that's sure
true of these: crystal clear trebles, sharp midrange, good specs (60 RMS watts,
49-21,000 Hz frequency response, 92 dB sensitivity), and an overall punchy,
lively feel to the soundstage. Bass is only average (weaker, in fact, than the
factory speakers they replaced in my Mazda 3), but there are no real negatives.
The adjustable rotating tweeter is a nice touch.

My only wish is that Infinity come back to it senses, so the next time I buy a
car I won't have to be hunting for what will by then be decade-old speakers.

Best I've installed yet.

Crutchfield Customer Review (What's this?)

I installed a set of these speakers in a friend's Ford Explorer. We used a Pioneer DEH-P2900MP CD player and two sets of the Infinity Reference speakers. The sound quality is great, better than both a pair of 6x8 Kickers that I had in a previous car and a set of Kenwood 6x8's that I installed in another Explorer. The highs are bright and clear but not overpowering, and the bass sounds excelent. These sound as good or better than the JBL 6x9s in my vehicle. Crutchfield got them here fast and for the right price too.

These speakers are great, once again infinity has come through with some great sounding speakers. They were very easy to install. They have very clear highs and great mids. These are amazing and defenitely worth the buy, I have owned several pairs of speakers and know my share about audio equipment and for the money these are great.

Outstanding silk dome tweeters.

Written By Dean, Homewood, IL on Sunday, July 29, 2007

Crutchfield Customer Review (What's this?)

My favorite home speakers have had silk dome tweeters, so I picked up a pair of these along with a Sony CDX-GT410U receiver for my Contour. Turned out to be the best investment in sound I've made in a long time. The highs are very clean and realistic sounding with none of the harshness usually found in car speakers. Vocals and instruments are very well-defined and natural sounding, don't be surprised if you hear details in your music you haven't noticed before . The bass is good for a 6x8, but I'm glad I left the original speakers in the back doors. They add just enough warmth to the bass to make the system sound really sweet. I can turn the Sony up as loud as my ears can take it, and the sound remains wonderfully clean and undistorted(and I do like it LOUD). A friend heard my system and ordered the same setup for his Ranger. He got noticeably more bass from these in his vehicle, they sound great on their own. I've heard more than my share of high-end stereo equipment, and these truly put out some high quality sound. And don't buy your car audio from anyone but Crutchfield. Their installation instructions and accessories make their already low prices the best bargain by far.

Not bad sounding speakers at all. Defineatly recommend getting an Amplifier with them.

Infinity Reference 6812cf

Written By Casey, Arkansas on Wednesday, June 13, 2007

I have 4 of these speakers (Front doors and Rear panel). I must say that they are much better than my old factory speakers. To get the most out of these speakers, you need a nice sized amp. I have a ZX 650.4 Kicker amp hooked up now, and they sound much better than when powered by my Panasonic CQ-C8803U Head Unit. The overall cone excursion is pretty big on these speakers, but they still lack on the bass below about 70Hz, but they are only 6 x 8's, so you can't expect ground shaking bass. I recommend setting a high pass crossover up to block bass below about 70Hz, because if you have it set much lower, the speakers will start to distort on high volumes. The tweeters reproduce pretty precise highs, and the fact that they rotate is nice when you want to aim them at your ears.

Overall, good speakers for the price. They are a great upgrade from stock, but if you want even more punch and low end, get the Infinity Kappa's and/or add a decent sized sub!

Crisp, Clean Sound

2005 Ford F150 SCAB
These speakers were an excellent choice for upgrading my stock system, I would have to say that I am impressed of how much quantity and quality you get with such a greatly priced speaker. I have paid a lot more for speakers that didn't produce this clean of sound. Being able to turn the tweeters in different directions really helps with the usability of these speakers, especially when your speakers are located close to the floor.
Pro's: the turnable tweeters, clean sound, and Awesome value.
Con's: none
Thanks again Crutchfield you guys ROCK!!!

Excellent Speakers - Highly Recommend

Written By Miguel, Goodyear, AZ on Monday, May 28, 2007

Crutchfield Customer Review (What's this?)

I have owned another pair of these reference speakers in the past and had them in another truck, these are phenomenal as a nice replacement speaker when adding a new head unit.

The stock speakers in my 2007 Explorer were 25w drivers that could barely keep up with the new Pioneer 9800BT that I had just installed. Once the Infinity's were in and I powered up the system, everything was clean and smooth. Bottom end played flawlessly, even on some heavy bass CD's and MP3's, highs were crisp and best the mids were silky.

These are superb, short of running a component system or tri-amped setup, you can't go wrong and for the price - OH YEA!

C-L-E-A-N !!

Written By Zembower, Lafayette, Louisiana on Sunday, May 27, 2007

I installed 4 of these in the factory holes of my Ford Taurus. Alpine head unit and Alpine 4 channel amp.

I have NEVER heard so many different instruments in my music.

During acoustical guitar solos, you can "feel" the artist bending the strings on the guitar - amazing.

If you're looking for some factory replacements for your Ford product, you won't be disappointed in these speakers by Infinity.

Great sound after break-in period

Written By Anonymous, Bradenton, FL on Friday, April 20, 2007

Crutchfield Customer Review (What's this?)

As a quasi-audiophile, I am aware that some high-end home audio gear needs a break-in period to sound its best. I did not anticipate that the same would be true of car audio speakers. But these speakers proved me wrong. When I initially installed them, I was mildly disappointed in their bass response. Mids and highs were good from the beginning. But after a few days, the bass response seemed to gradually increase to the point where the sound is now very well balanced across the entire audio spectrum. A very good deal at their price.

Simply Amazing

Written By Jonathan, Longview, TX on Wednesday, April 18, 2007

Crutchfield Customer Review (What's this?)

I installed my door speakers (front and rear) tonight. I have to say, the improvement over my stock speakers was simply astonishing!

Not only did my highs sound immensely better, but because of the quality of speakers these are, I could also adjust the sound quality on my subs to get more bass without distortion.

I'm sure they don't sound as good as some other high end component speakers (3 way) but, if your used to stock speakers, you will be blown away at the clarity and precision these speakers put out (that is if you have a aftermarket deck).

Installation was simply a breeze! It literally took about 10 seconds to hook up the new speakers (aside from removing the door panels).

Crutchfield was great with their instructions! So simple a caveman could do it!

Exceptional 6 x 8 speakers

Written By Lou, Pennsylvania on Tuesday, March 13, 2007

Crutchfield Customer Review (What's this?)

Car: 1999 Ford Contour SE
Audio: stock head unit, Infinity 6812cf front doors, stock speakers rear doors

The Infinity 6812cf are a great improvement over my stock speakers. Voices are now clear and have distinguishable S, F, V, and all the other sounds that used to get lost. Mids and highs sound great; horn reproduction is amazing. And this is from FM radio through a basic stock head unit.

There isn't substantial bass, but I don't expect any from speakers this size. A compact powered sub under the seat should give me the bass I want. Add 6812's in the rear and a better head unit, and these speakers will do their job brilliantly.


Written By Greg, Rogers, AR on Tuesday, February 13, 2007

I don't know if it's just me, but after i put these speakers in my rear deck, i didn't hear much of a difference from my stock speakers. I am going to redo the connections and may even solder them to see if that helps. If that doesn't help then I'll just cut my losses and try some other speakers.

Written By Justin, Griffin, Ga on Monday, January 22, 2007

Crutchfield Customer Review (What's this?)

The Infinity Reference 6812cf sound great. I ordered a set for the front doors. Then reconsidered and order a set for the rear doors as well. Crutchfield thought I had a duplicate order and emailed me to double check before charging me for 2 sets of speakers. That is customer service at its best. They will have my business for ever. Now, it took about 3 days for the speakers to break in but the bass is decent and the mids and highs are great. I am useing a stock Ford HU now but have ordered the JVC KD-HDR1. I'm sure the sound will improve if that is possible. In my opinion you will not be going wrong with these speakers.

Great sound

Written By nwagtmustang, Beaverton, OR on Friday, January 12, 2007

I have a mustang with the mach64 sound system. Installed pioneer head unit and used the infinity speakers all around. I wired the speakers directly to the head unit. These speakers sound awesome. I usually listen to rock. However to test the speakers I used a mixed cd with classical music. I never heard the 1812 overture sound so awesome before. The cannons really come alive with the Infinity Basslink woofer. I never used Infinitys before, but will always use them for now on. The 6.5 speakers in the rear sound awesome as well. Buy these speakers.

solid performer, reasonable price

Written By truckie707, Dover, NJ on Thursday, January 04, 2007

I replaced my factory speakers in my 97' Ranger crew cab and ran a 50x4 amp to drive these balanced, crisp performers. I finished the ensemble with an Infinity Basslink I system. I like my systems to be balanced and I struck it rich with Infinity. I'm a big fan. The directional tweeters really allow for tuning the sweet spot. Highly reccomended!
I liked this product so much I replaced my whole system in my Saab with Infinity product too!

I think the speakers are great. I bought 2 pairs and replaced the factory speakers in my 03 Mustang. I mated the speakers with a Profile 1040 (80x4) with a JVC Headunit and a Kenwood 24 band graphic eq for optimal sound and these speakers are loud. I must give these speakers a good mark because they produce the bass and the highs unlike other products that I have used.

Excellent replacement solution

Written By DPM, Philadelphia, PA on Friday, October 20, 2006

Crutchfield Customer Review (What's this?)

I replaced the original speakers in my 2006 Ford F-150 with these and the audio improvement was great. Much cleaner sound than the factory originals. The mid/highs are a little more pronounced than the factory originals so you likely want to tweak your equalization settings. Don't recall if the original factory radio allowed for this, so your best results may mean opting for a decent radio to really tune it well to your liking. The bass output is very good for speakers of this size and I've decided to pass on needing to get a sub-woofer since they do sound so nice. For the price, you cannot go wrong. As always Crutchfields installation instructions were flawless and I was able to put all these in (front and back), replace my radio, install the multidisc changer all in less than two and a half hours.

These are great speakers for the buy.

I purchased 2 sets (total of 4) for my 94 Explorr. I was worried at first that they wouldn't be nearly as nice as my friend's component pair of Infinity Reference 6810cs, but the sound quality is close. They fit perfectly into the four door's of my Explorer, and I was done installing them in about 2 hours (first timer). You can get pretty much a full sound depth with a little tweeking of the treble and bass. Incredible highs, but not unfomfortable or ear piercing with some adjustment.
They sound like very expensive speakers!


pretty dang good

Written By Mikey, Edmond, OK on Wednesday, August 30, 2006

Crutchfield Customer Review (What's this?)

These speakers are great upgrade speakers to work with a high performance head unit. They sound great until you get kinda loud (around 40 vol) and the bass gets kinda sketchy and isnt all that smooth. I dont really mind this because I'm about to add two 10" woofers and with most head units u can set it for the speakers to only project highs and mids letting the sub handle all the bass. Im sure this will settle my problems and will continue to love the speakers. Great deal for the money and was very happy with all Crutchfield supplied me with!

What a Speaker!

Written By MGoBlue, Lehi, UT on Monday, August 28, 2006

Now that I have had these speakers a couple of weeks, I feel that I can write an educated review. I have 2 pairs in my '05 Crew Cab F-150 powered by an Alpine 9857. I cannot believe the sound quality! As long as you have realistic expectations about the amount of bass that is produced you will be blown away! It is hard to produce deep bass from this format of speaker, so not Infinity's fault. I cranked up a song that was all vocal and piano to see how loud they could go without distortion, my ear drums started to bleed before the speakes had any kind of distortion! For the $$$ there is none better.

Crutchfield Customer Review (What's this?)

I tried both these Infinity Reference 8012cf's and the Polk db570's to replace the factory speakers in my Ford Focus wagon, but I hardly noticed an improvement in sound quality. I tried them with an amp thinking then I'd notice the difference, but no. I ended up finding that a pair 5-1/4" 3-way Kenwoods carried the highs, mids, and higher lows much better than either of the 5x7's I tried. I'll be cutting holes and using spacers if necessary to put 6x9's in the rear doors to carry the mid-lows, and I've got a small sub for the deep bass. I don't recommend replacing your 5x7's in a Focus with these speakers.

Fantastic speakers after break in period.

I bought these speakers for my Ford Explorer, where I am running an Alpine CDA-9835 head unit with the premium factory amplifier, and no subwoofer. I also installed XTC baffles (available through Crutchfield) with the speakers. At first, I noticed somewhat improved mid range and treble. The bass was a little tighter, but no more powerful than the factory speakers. After three days, however, I was surprised to hear how much these speakers bloomed. Mid and upper range are now silky smooth, the bass is noticeably more powerful than the factory speakers, and the imaging is also excellent. I have never owned car speakers that improve so much after burn in, nor have I ever heard speakers in this price range sound this good.

Based upon other comments from satisfied buyers on the Crutchfield website, I puchased a pair of 6812's (door) and a pair of Polk 570's(rear deck)for my '02 Thunderbird. I can honestly say that the 6812's are the best sounding speakers (using the factory head unit) that I have ever heard. Bass response as well as highs are outstanding. The Polks were not near the equal to the 6812's and appear to need more power to provide better sound. I would encourage anyone wanting to significantly better their sound, using a factory radio, to purchase these speakers!

I went with the same set-up as Mack from Long Island (Polk db570's for the rear speakers and these in front) except I have an aftermarket headunit (and my Ford of choice is an Explorer). With the fader set a couple of notches toward the rear and a little EQ tweaking, it is an awsome set-up. The detail and clarity these provide for the highs and mids is amazing, and the 570's give you enough low-end to get you by. (Thanks for the advice Mack.) I am gonna add the Rockford 2-10's and amp package Crutchfield is offering and call it good.

I have a F350 standard cab truck with an after market clarion head unit (50 some odd watts per channel ). The 6812's are in the back of the cab behind the seat, as well, I have the infinity component set mounted up front and in the doors. I must say that the sound that these speakers put out is as rich as I have ever had...and it's in a truck! You will be very happy with your purchase. I would also like to say that when crutchfield says that they have the plugs or mounts or whatever to fit your vehicle...they do and they have never been wrong! Five stars for crutchfield as well.

They are crisp and clean.....However the one limitation is the bass. These speakers cannot handle bass.
I recommend that you purchase 2 pairs only if you have a subwoofer in your vehicle. In my truck I put these in the front and the polk db570s in the back, the polks handle the bass great, and with these crisp highs you are set. What are you waiting for BUY.

Very suprised in how well they handle the mids and have very crisp high tones. For the price you can't do any better.

Product Research


Plus One+ Woofer Cones: Each speaker uses a cone significantly larger 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 a significant increase in efficiency.

Woofer Materials: Each woofer is constructed from Injection-Molded Polypropylene. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. It is also lighter weight and more rigid for decreased distortion and improved bass response.

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.

3/4" Silk Dome Tweeters (UniPivot Design): Each speaker uses a 3/4" edge-driven silk dome tweeter for smooth, accurate highs. The UniPivot tweeters are angled (non-adjustable) and may be turned up to 355 degrees for optimum imaging and in-car frequency response.

Note: The tweeters are not made to turn 360 degrees. If they are turned 360 degrees or more, they will be damaged.
