Infinity Kappa Perfect 300M

Looking for the ultimate for in-car audio performance? You've found it. Take your Infinity component system to the next level with these Kappa Perfect 300M speakers.

Built with Infinity's Perfect component systems in mind, the 300M adds yet another layer of depth to already-superbly engineered audio products. Just toggle the crossovers from two-way to three-way on the Kappa Perfect 500, Kappa Perfect 600 or Kappa Perfect 900, add the 300M speakers and get a fuller range of sound.

From the extra-strong cone to the rugged basket that houses everything, the 300M is built to add a tight, accurate midrange response to your system. Linked up with full-size woofers and tweeters, these mid-drivers complete the Perfect systems and produce the sound that others can't. Get even more from your components to make them truly perfect.

Sound construction


These 3.5" midrange speakers are built with Infinity's patented Plus One woofer cone, engineered from carbon fiber to optimize SPL and minimize distortion. An oversized voice coil flattens the frequency response, giving some of the most accurate sound reproduction available. On top of that, they're more reliable, making sure you get more life out of your speakers.

If this is the last piece for your Perfect system, go ahead and add these 300M speakers to your cart. Hear and feel the difference on your next ride.

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.

Very Detailed!!!

Specs:
3 1/16” cutout diameter (basically a 3” with pressure fit ability)

75 watts RMS per speaker (I have more going to them but no sign of stress crossed over at 250, 280 or 315. I haven’t tried lower due to application)

Dry Carbon Fiber cone (no clear coat/not glossy but looks great)

Sewn-in Tinsel leads (I was so excited to see this tech on a 3.5”)

NO rubber magnet boot cover that I can find/see/touch.

Install:
Currently crossed over at 250-3.6k @24db (Lazy install or I would extend range to 5k)

Running

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!
