Big, Warm, loud, well made and detail

The following review is for Perfect 300M, which is a part of the bundle you are viewing.

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!

The following review is for Perfect 300M, which is a part of the bundle you are viewing.

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

The following review is for Perfect 300M, which is a part of the bundle you are viewing.

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!!!

The following review is for Perfect 300M, which is a part of the bundle you are viewing.

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!

The following review is for Perfect 300M, which is a part of the bundle you are viewing.

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

The following review is for Perfect 300M, which is a part of the bundle you are viewing.

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

The following review is for Perfect 300M, which is a part of the bundle you are viewing.

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!
