Big, Warm, loud, well made and detail

I paired these with the kappa perfect 600 3-way component set. These complete the 3-way system with the passive crossover. The perfect 600 is already a good 2-way but add this midrange and you be hearing things in song you didn’t even know existed. These speakers are well hilt and look beautiful. Hand tighten or you will strip terminals. I’m sending 75w from a rd400/4 and they sing. I will eventually go active to control each I do speaker level but for now I’m blown away. These are big so make sure you have room and depth to install these. Some modifications might be necessary.

Its perfect.. really its Perfect!

I bought (2) sets of these midranges for both the front and rear doors of my 2003 Altima. It is paired up with the Infinity Perfect 600 components. The sound is indeed PERFECT! These are an upgrade to the infinity Kappa Co -axials powered by (2) Kenwood Excelon XR40004 set in 2 channel mode to each set of Perfect crossovers. Such beautiful sound .. crisp, not overly bright, detailed, full and Loud!! I believe this is my best set of speakers thus far. I couldn't be happier.

Perfect. No pun intended

Sounds great as a center channel speaker in my 2017 Super Duty. Very smooth, blends well with the pillar tweeters to complete the soundstage.

Pure Perfection Amazing Sound!

I would highly recommend these amps to brighten your center stage and raise the quality of mid range sounds, especially voices. I have a 2018 Dodge Charger GT and placed these in the dash (left and right) running of the Alpine V9 pdx and they handle all the power it puts out and love it. I have not tried these speakers off the factory deck but I have read nothing but improvements there also. If you want clear, perfect quality front stage and are running an Amp these baby's are Perfect. In fact if I had more 3.5 speaker areas I would be placing these speakers in all of them they are THAT good!

Infinity Perfect 300m Midrange Driver

Amazing sound quality. These reproduce sound at amazing volume without distortion. Great weather amplified or not. I installed in my 16 Ram ant it brought the stock head unit to life. I would recommend to anyone who covers quality at a bargain price.

Outstanding midrange speaker

I’m 62 and have been a car stereo nut since my first Craig Pioneer eight-track in 1974. The Perfect 300M is the best 150 bucks I ever spent on speakers, they are incredible, warm with excellent detail. I’m more of an SQ guy than SPL but they will play loud without any harshness, I couldn’t be happier. These replaced Audison Voce 3 in mids which are very good but don’t hold a candle to the perfects. I installed these in my 17 Outback 3.6R which wasn’t easy but more than worth it. Powered by Kenwood XR600DSP. Highly recommended!

Infinity Perfect 300M Kappa, you know, you know.

I purchased these to throw in my Mustang. Before I did that I built a little box for them, powered them with a nice punch amp and WOW! If you're into audio then you probably know Infinity Kappa is a underrated and they really do sound great. The price IMHO is worth the value you're getting. They feel sturdy, like they'll last a normal person a long time... Anyway these things were clear and loud, I was blown away by these little guys. I now need another pair, sadly I accidently dropped the box and poked hooked in both of them. ???? So they never made it to my Mustang. My garage is a hazard, what can I say.

Holy grail of speakers

So I have owned 15 to 20 different car audio systems in my 21 years of driving and I also owned a high end home theater installation company in south florida so its safe to say I know good sound quality. This Kappa 600 system is the best sounding system I have ever had in my car or anyone's car for that matter. It is so dam clean and most importing its clean even when playing loud which was the most important factor for me since I listen to my music loud a buck. The 6.5 weigh more then some peoples subs and it built very well. the crossovers are again, as big as some peoples amps. Now I know the price tag isn't cheap but if your looking at these then you have seen other sets like JL Audio (which I just had and replaced with this) Alpine, Focal, Morel, CDT Audio. Now Ill say this Kappa 600 is a much much better value since I have paid more and sometimes even double to have alittle less quality sound for the names listed above. As for the rest of my system I am running 3x Sundown 8saV3's to a CT sound 3k Team amp, and the kappa's are on a Infinity KappaFour 4ch amp for now as I just installed it using the included Passive crossovers. I was thinking I would just do an Active setup using a Helix DSP but figured I would try the Kappa passive crossover for now. Last but not least I am only running this setup as a 2way because I am waiting on my custom pillars to come in so I can goto the 3 way system and I can only imagine how much nicer its going to sound which is really hard to believe to be honest. Hats off to Infinty as I knew this would sound good based on other reviews but I really didn't think it would be the best system Ive heard SQ wise.

Best I ever bought

It sounds so nice clean and clear no matter what the volume level. Infinity speakers are perfect for Infiniti car

Wowzer...

So I just installed these in my 2017 F250...WOW. Ive never heard such a clear and amazing set of speakers. I have a 2x200w RMS Kenwood amp that will play these babies at 100% volume with zero distortion. Just amazingly loud, clear and crisp sound. The last kappa's were known for really bright tweets, these are prefect, not too bright, just perfect reproduction. I wouldn't hesitate to buy these again.

Crisp & Clear

this component system sounds so clean thanks to the crossovers that came with it, Infinity never fails me.

Fannntastic

This is for sure Kappa top of the line... highs are pure and clean and lows are what I expected

By Anonymous on April 30, 2019 Verified purchase

Wow!

Upgraded my 2014 Tundra stock system (non-JBL). Kept the stock HU and added a Kappa K4 amplifier with these Perfect 600's in a 3-way set-up with Perfect 300M's in the dash and 62.11I's in the rear. A Dremel was my best friend for this install as I had to make more room in the stock space for the mids and then used a hole saw to mount the tweeters in the A-pillars. I had to Dremel the back of the recessed tweeter housing - shaving everything down except for the bevel that angles the speaker towards you.

Overall, I am pleased with my choice and I'm incredibly impressed with how the mids and tweeters sound together. It is a very pure, full sound that captures every single detail of the song. I am discovering discrete parts and details of songs that I never noticed before. I am, however, slightly disappointed with the range of the 6.5"s in this set up, but I imagine in a 3-way the lows are distributed almost evenly between the dash mids and 6.5"s. I strongly suggest planning to add a sub or two to round out the sound. For reference, I mostly listen to progressive metal/rock and haven't tried to play anything that is primarily bass driven yet.

Pros:
Very impressive, clear mids/highs
Infinitely better sound than stock

Cons:
Completely custom installation (at least for a Tundra)
Lack of lows - basically requires a subwoofer for full range

sorry folks but Infinity makes it easy for my system to sound like it was installed by a pro... this package is crystal clear with all the different cross over tones love em.

Very nice speakers

These speakers are the best I've ever owned (also the most $ I've dished out for some speakers, but you can tell the difference when you jump up in price point even from $200-300 components). Got these when they were on sale for a decent deal and I felt justified in dishing out the cash for some nice components. These things are loud, crisp, clean and clear. Have both sets hooked up to a Kappa K4 giving them the whole 100w these want and they handle it beautifully. Couldn't be any happier and looks like I won't be swapping out these any time soon.

CONS:
-Crossovers are HUGE, almost the size of 3 blu-ray cases stacked on top of each other. Due to this, I had to mount the crossovers by the amp for the fronts and run the speaker wires up for each channel as my front doors weren't able to accommodate the crossover. The rear doors I had to do some serious MacGyvering to integrate the crossover into the door panel. Overall, this made the install a serious PITA and I had to split it up into 2 days for doing both the fronts and rear components.

-Speaker terminals on the woofer could offer a little more clearance. It was a bit aggravating to jam the speaker wire in there with only about 1/2 inch of clearance between the terminal and the magnet housing.

-Crossover terminals can be very aggravating to jam the speaker wire in there. They are solid once they're in there, but it was another PITA to jam the 14AWG wire I had in there nicely with the screws in the way

PROS:
-Loud, crisp, clean and clear. Give them a week or two for break-in and they sound beautiful. Maybe not complete audiophile components, but they sound damn good and have that full, beautiful and complete, Harman/JBL/infinity sound

-Very solid and durable-looking feel to these; these should last me a loooong time. I don't see any reason to swap these out as long as my car is running.

Overall, the crossovers made the install a total PITA, but it was completely worth it
