Good Speakers

I would recommend this set, they sound crystal clear and worth every penny. I have used them before and they sound great in both vehicles.

2004-2007 sequoia JBL replacement

Replaced the rear door speakers in my 2005 Sequoia. Wow EXCELLENT. WORTH the trouble. Too small for the front door IF you have JBL 10 speaker system. An 8" woofer works it already has a mid and tweeter in the front. (FACTORY AMP)

Great quality for Infinity Kappa

This is a great company!!! Service was fast and the price was very good for the quality!! I do recommend

Great speakers

These sound amazing when you give them more power with an Amp, they sound great without being amped, but really bring the music to life with more power! Get these speakers and you won't be dissappointed!!!

Infinity Kappa 62.9I

Its fine

Great sound

Great value for all the accessories that came in package

Some of The Best Speakers You Could Get

I just bought these speakers about a month ago, I got em to replace my old Kenwoods that just didnt give me the quality I wanted and from the first moment that I turned on my radio I noticed a huge improvement every note is clear and crisp and they get pretty loud. Im planning to amp em up soon with a MTX Thunder Elite amp cant wait to hear em then.

Infiniti kappa 62.9i

I bought these speakers 6 months ago. Great speakers at a great price.fast shipping. Would definitely recommend!

good speaker

That was a good buy and sound good and like design and i will buy more

infinity Kappa 62.9I

I have had alot of speakers and i think i like these the most there not as sharp as my old memphis but they are sharp and verry loud and if you put them on an amp they will blow you away and can keep up with a audioque HDC3 18" sub ...I am going to put them in my other cars...build quality is better then you think your going to pull them out of the box and say wow!!..

great speaker and great seller

Speaker is great with good sound and solidly built. this is my second pair cause the first were defective, but let me mention that sonicelectronix is a great seller to deal with. they worked with me despite of my return being damaged during shipment. they still sent me a replacement with no problem.

Amazing High and Mids

I have two sets of these speakers and i love them. I have them running at 100 watts RMS off of a 4 channel amp with a Kenwood head unit. I haven't been able to get the bass I am looking for out of them but running them with a sub woofer is an all around amazing system. If you want a reasonably priced speaker with amazing highs and mids then these are your speaker.

Clear Great Sound !

High quality sound, easy to install, fair price, I would recommend them.

Sounds Amazing

Really happy with the speakers I bought! Really loud, clear and plently of bass if needed! Owned it for 6 months still blasts strong. Broke my other kind due to off-roading but that's my fault! Lol
Just buy them and you'll be happy!

Good buy

The infinity kappa 62.9I are good speakers for the money they have rich sound and ample bass from a 6 1/2 inch speaker. I would recommend them.

great sound

I currently have this set connected to my head unit and with bass and volume all the way up doesn't push them to the max they need a separate amp relly good value for the price ima order another set

Sounds great

I actually put these in my boat. They are sounding great. I replaced the stock Fosgate speakers with these infinity and you can tell the difference in sound quality. Deeper, more rich, warm sound. Great price too!

Best speakers I've ever installed

Paired with a 75 watt X4 amp, simply amazing the power and clarity I'm getting. Didn't even need to install the subwoofer...you can barely hear/feel it. If you want a sub to keep up, make sure you get a 10" or 12". (A single 8 is what I'm using)

Better than I Expected

These are very clear and bright-sounding speakers. I did not think the bass would be all that adequate, but it is definitely adequate for classic rock. Probably not for rap, though.

Great sound at a great price

Bought for a 1997 Cherokee. Fit in with a few simple modifications. They are a little too deep for the doors but no cutting was required. Sound great and will be buying a second pair for the back. Would recommended to anyone looking for great mid low and highs all around. Sound fine just off the head unit as well

great clarity

Running these off a kicker DX 4004 amp. Very impressive for a non-component 6.5

Great Value

I put two sets of these speakers along with a JVC KW-XR810 stereo in my son's '03 Celica GTS. We were on a budget so we did not go with component speakers. I was amazed at how much better this system sounds than the factory stereo with the JBL speakers. The bass that comes from these 6 1/2" speakers is unbelievable. I was leaning towards staying with a JBL speaker but after I did my research and compared the performance specifications these Infinity Kappas were clearly the best bang for the buck.

Personal Opinion

I was trying 62.9l The Infinity Kappa rear door of a Peugeot 307. The doors were soundproof, but ue into the car door is ue boring, because they originally come factory coaxial cable bolted to the panel, so we had to supplement a wooden ring to fit.
Went with a Kenwood stereo and X994 volume of 24 sound great and have very good shot, a sound very linear, more than 26 distorted, but is normal in non-amplified speakers.

Infinity Kappa 92.9I

Since I have installed these speakers in my jeep's sound bar, the clarity has been amazing. They totally blew the factory sound out of the water. They would probably sound better if I were pushing them with an amp, but even without one they still rock.

Great Speakers

I used these to replace front door speakers in a Saab 9-5. They looked excellent, had no issues with the install and they sound wonderful. \\they went in a very good HK factory system. A big improvement but are of the quality that with upgraded amps they would really shine. A great deal at this price point as well

infinity 62.9i car speakers

I did the self install on these speakers. The job was not difficult. You just have to take your time, no one is going to do a better job then you.!! The TWO most important thins you must watch out for on the install: The depth of the speakers with your glass windows and the wire dongle from the speaker. Not a BIG Problem.!! I just drilled two holes on the side. Slid a plastic Cable Tie in one hole around the dongle into the other hole, then tie off.!! Held secured, no rattle.!!! These Speakers are Wonderful, it is worth the investment of your time.

Crazy loud speakers

Loud speakers with great bass. Clear and crisp good price for the quality

Very clear sound....

Hi, i bought two pairs about six months ago and I'm very satisfied, they are connected to a Phoenix gold 4 channels and let me tell you that they can take A LOT of power....the limit is my ears....:)

Good speakers and value.

I have installed these is both of my teenage kids cars and they have held up very well. Good sound and very durable.

amazing durability and sound quality

5 out of 5 all the way. Crystal clear highs and great lows for the price. Definitely my kind of speaker because they are extremely durable as well.

Great Speakers

These speakers are amazing for the price. I've had them for a year in a Toyota Celica with two Memphis 15's and I've only blown one speaker so far. They are extremly loud and fairly cheap, they are definatly worth the money

Great product for the price

I bought four of these speakers about a year ago for my tacoma and noticed a great improvement over stock speakers. Installation was fairly easy. Adjustable tweeters are a plus on these speakers and produce great highs as well as bumbling lows. for 6.5" speakers these are a great value.

Amazing

I am not sure if its just because I have been listening to the stock speakers for so long but these speakers pump hard. I have my amp tuned to only play the high pass through these speakers and they still hit pretty hard with a decent amount of bass. I would definitely recommend these speakers to anyone.

Exceptional Speakers - Exceeded My Expectations

Every pair of 6 1/2 speakers that I have purchased throughout the years has been a disappointment, mainly due to the weak bass and poor imaging. These beauties were definitely an exception!!! Installed in an 07 Accord Sedan, these babies produce resounding highs, balanced mids and SURPRISINGLY low lows. They are a fantastic complement to my 693.9i speakers. And the kicker is that they are only powered by the stock stereo. I'm satisfied as-is and can't wait to see what they sound like with an amplifier. The only down side that I can think of is that the base is lacking at low volumes, but an amp would cure that. If you're installing them in an Accord use the Metra adapter #82-7803 and some self tapping screws and your in business without cutting or fussing. HIGHLY RECOMMENDED.

simply AMAZING!!!!!

ok so i have a 2001 ranger edge that i am installing my stereo system in. first off my stock speakers are 6x8's and i prefer round speakers, so i purchased a 2 sets of scooche speaker 6 1/2 mounting brackets for the 6x8 speaker openings, these infinity kappa's fit perfect. so i wanted to get something that i could afford but still sound AMAZING!! these are by FAR the speakers to get. i bought 2 sets and i dont even have my aftermarket deck and amps in yet and they sound AMAZING!! i am buying a Kenwood eXcelon KDC-X792 deck and then i am buying a decent 4 channel amp to power these. i have an ascendant audio arsenal 15" subwoofer thats going behind the seats so i definitely need a set of speakers that can get loud sound great and be able to overpower that sub if needed. these are them! i love the look of these speakers with the woven fiber cones and the ability to aim the tweeter at the listener really makes a difference. the external crossover is a MUST with any good audio system. i used to have a set of polk audio momo championship speakers i loved them, actually the two are very similar to eachother!!! but they dont make them anymore so, needless to say i have these bad boys. if your looking for a great set of speakers but dont have all that much money, jsut save up an exra bit of money and get these, dont be in a hurry, you'll regret it. i mean these speakers compare to sets for 3 times as much. cant wait till i get the deck and new amps. i'll get back to you when i do!!!!

Best

These are really good got these on a tahoe on all four doors and it souds amazing i had kickers and these are way better

Great speakers!

I would recommend these speakers to anyone wanting to upgrade a factory sound system . I installed these in my 2006 GMC with bose system . Definite improvement from factory speakers. Durable and have great sound . Very hard to find 2 OHM speakers but Sonic Electronics had them at a great price. These speakers play crystal clear at full volume.

AMAZING SPEAKERS

I have these speakers in the back with the component infinity 6030cs' in the front and theyre running off of the infinity 475a 4 channel amp. the highs get REALLY loud and the sound is powerful and clean and they compliment my 12 inch l7's nicely!

Great quality

These sound great in my car! The quality of sound that comes though the speaking is top notch.

Superb sound at a fair price!

Ive been using Infinity Kappa series speakers for YEARS in several different cars and trucks. The 62.9i Kappa’s are incredible! I installed 4 of them in my old 2000 Rav4 but have used this same speaker in my Tacoma 4x4 and in the doors of my 2000 Mazda MX5 Miata. I must say that they come alive with a proper amplifier or high quality head unit. Do yourself a favor, set the bass at 0 and begin turning the mid and high end up. ONLY after feeding them some power!! Im feeding my Kappas with about 20 wats RMS all the time, my Bass is set at -1, mid at +4 and high at +5 and it sounds incredible! Im running them in foam baffles with the bottoms cut out too. I only drop the ease of use category because of the factory installed outboard cross over, it makes installing them in certain locations a pain...

great little speakers

Very good sounding speaker that handles a good amount of power. I run 75watts rms to them and they sound good. I recommend using hushmat or dynamat when placing them in the doors of your vehicle. Also get some tie wraps or aka zipties for the little crossover.

The reason you should buy name brand speakers

I have these in my 94 camaro and after owning sony, pioneer, jbl and kenwood I can honestly say these are the best. No other speaker this size gives this much bass for being so small.very loud and clear but to really get the best sound you need to amp them and have a good head unit with a good level of adjustment. They will still sound good just off the head unit but not once you turn the volume to the max. my kenwood plays them good just a few ticks under its max. You can adjust the angle of the tweeter buy only twisting it so DO NOT PULL ON IT TRYING TO MAKE IT PIVOT cause it doesn't. I thought i would adjust the crossover and turn the tweeter down but it gives you perfect detail without hurting your ears. I mostly listen to hip hop which can some times be bass heavy and blow most speakers so the built in crossover is nice

Brilliant!

Easily best bang for you buck. Have these installed in a 2001 civic sedan in the front kicks and back panels. These speakers were a super easy install. Ran them originally off the head unit (Sony CDX-GT930UI) and off the head unit they sounded beautiful. Then amped them off a cheap 4ch amp i had lying around and sounded gorgeous. The bass response off these is amazing for a 6" coax. They were a little bright for my tastes at first but if you hit the tweet button it will throttle it back -3db and it sounds absolutely perfect. Oh yeah and these are much cheaper than a lot of other coaxes ive dealt with in the past but sound just as good if not better than their more expensive counterparts. Worth every penny and versatile for running off head unit or amped. I highly recommend these.

So how do they sound?

What can I say, choosing speakers isn't easy. There is no way to listen to them all before your purchase a pair. You can go to Worst Buy and play around with them but you can't get a good listen in before a store goon comes up to bother you. Honestly, what are you to do? In my car I have an Alpine 9885 head unit, stock speakers, Kappa Perfect Sub hooked to a Kappa One Amplifier. I was between getting these infinity speakers to go along with my infinity Sub or getting Alpine Type-R speakers to go with my head unit. Long story short I bought the Infinities for two reasons; a) Type R speakers were sold out on this site and b) the Infinity's were 2 ohm which is a plus because I am running them off the head unit. So how do they sound? Well, they sound awesome, these things really sing. Running off the head unit they still get plenty of power and get way to loud for me before they distort. The sound is clear and the lows are complemented very well with my sub. I am glad I bought these speakers. I have no idea how the Type r's would have sounded but I don't care because the infinity's are great speakers and I am happy and that's all that matters. Also, if you read this entire review than you are probably an audio freak like me that spends way too much time scrolling the products on Sonic Electronix and I just thought you should be aware of that. Keep your volume up and your windows down, You'll hear me before you see me.

good sellers

I recommend Sonic Electronixbecause I like the way ideal with them and they're fast shipping specific and details on their descriptions of the item

Thumping speakers

I put these speakers in my 2003 dodge Dakota with the infinity system because my old speakers were blown due to them being 11 years old and some very heavy bass. I replaced them with the 62.9i's and they are great replacement speakers for a factory system with an amp, wonderful bass and great sharpness. I'm highly satisfied with them, they ROCK!

Infinity Kappa 62.9I

Great speaker, excellant sound, watch mounting depth. Pig tail is awkward when mounting as front speaker.

infinity kappa 62.9i

These speaker rock!! They support surround sound and they sound very clear even at high volume. I recommend them very highly to anyone.

sounds great

For the money these speakers sound great.

Great Sound

These 2 ways have a great sound once amplified, but were lacking without the amp. I would recommend them to anyone planning on amplifying them.

Great buy

For the money you can't go wrong with these speakers exactly what I was looking for , have to replace one more on the dash board & I will go with infinity

Great sounding detailed speaker

Infinity has been my standard for over 15 years now with infinity Kappa's as my go to speaker. These speakers are replacing the former set due to one of the door speakers developing a rattle in the speaker after a few years of daily hard use. This version of the Kappas excels the earlier version that I had installed as far as build quality and slightly better in term of sound quality. I appreciate the built in crossovers and rotating tweeters that other manufacters do not offer. I actually purchased another manufacturers speaker but returned them since they did not match the sound I had grown accustomed too with the Kappas.

Great speakers

These are great speakers everything about them great sound clear and u can't beat the price

awesome speakers for the price

I put this on a 95 honda paired with 2 6.9 in the back and the sound is amazing crisp clear sound.I would definitely recommend this speakers they are solid

LOVE LOVE LOVE my Kappa's!!!

Great sound, full range, and can handle some POWER, so please, GET A AMP!!!!

Awesome sound

These speakers are clear with an awesome sound. They handle a wide range of music. Great value. I would rank the sound quality alongside of speakers priced twice as high.

best speakers in the market

hands down! If you don't believe me, try it yourself! It's a party in your car

Great Bike Speakers on 2014HD

Got these to replace the oem speakers in the front fairing on my 2014 street glide. The originals were 2 ohm, so I chose these as a direct replacement. HUGE improvement! much more clarity, punchier bass, crisper highs, and a good bit more volume. I ended up added a Fosgate PBR300x2 amp and the Infinitys really came to life. Bike sounds better than most cars now. Only MINOR complaint is the crossover/connection point hangs off the speaker so you have to add extra steps for mounting it.

Awesome Deal

These are some good speakers! I would recommend them to anybody! The sound is amazing, you want these in your car! Quit stalling and buy them already!

Awesome

GREAT SPEAKER , WORKS BETTER FOR ME ON A AMP BUT GREAT UPGRADE FOR STOCK SPEAKERS.

Pure Sonic Bliss in small ride!

These are installed in a old school Toyota that could only fit 6" speakers in the doors.. powered by a Kenwood Excelon XR-4S. WOW! Nice quality sound that won't break the budget. Get these Kappas .. you will love them. They are crisp, full and dynamic! Nice SQ speakers. Good job Infinity!

FANTASTIC COAXIALS!

Absolutely LOVE these coaxials. These are 2 (ok 2ish) ohm speakers so they get the perfect amount of power from your amplifier or even from your radio's built in amp. The tweeters are not overly metallic and have a pure natural sound. Very reminiscent of the Emit-R tweeters in my home speakers. PLUS they are directional and have the ability to attenuate their output to easily match your stereo and personal preferences. Lots of midbass from the oversized woofer cones and all nice and tidy in a great 6.5/6.75 package. These went right into the rear doors of my Traverse and match the 3.5" kappas that I installed in the 3rd row factory holes. Beautiful speakers, beautiful sound.

Awesome Speakers

My brother bought these for his car back in the early 2000's. I was amazed with the sound quality and bought some for my car at that time. I've been buying these ever since then for my vehicles since the quality and durability is excellent.
