Speaker Specifications

Series
This is the manufacturer product line of speakers.
Kappa Perfect (Infinity)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
6-1/2"
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way Component System
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Aluminum
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Deep-anodized aluminum
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Rubber
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
400 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
100 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
90 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
75 - 23000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
2-3/4"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-1/16"

meh at best

October 13, 2010

I didn't really like this set , they weren't worth the money to me, an equally valued set from JBL did much better, the tweeters of this set were very harsh and bright, but to harsh, couldn't do some music very well.

bah

April 29, 2010

I really don't like these, the mids are very good, with very good clean crisp hits, but not to powerful. i got them because of infinity being known for their bright highs, i wanted them to lead...but aside from being very bright, they have no power behind them, the tweeters were extremely twangy sounding in comparison to the JBL's in my rear seat set. they really aren't sharp at all, they can produce acoustic guitars and vocals decently, but they are worth 100-120$ tops, which is pathetic since this is infinitys top end set.

Fantastic Reproduction and Stage

October 24, 2012

I've paired these with a Pioneer D9500F 4 Channel Amp and Pioneer 80PRS headunit, deadened the doors with dynmat and I can honestly say that the quality, clarity and precision of these speakers is superb. These speakers reproduce higher frequencies extremely well. If you're after speakers for mids and highs, don't look past these at all (Note: I've got tweeters at -3db as they were a little harsh imo). Would recommend to supplement these with a sub or some kind to fill out the lower frequencies (I have a small 6 1/2 in a sealed enclosure).

prefered kappa 60.9cs

May 29, 2012

I purchased these online and installed them in my 2006 corolla. They replaced the kappa 60.9cs. I was not really impressed by them, I love the infinity sound and I highly recommend the kappa 60.9 cs. The tweeter on the perfects were to quiet and the components sounded like one big tweeter when you really turned them up. I hightly recommend kappa 60.9cs they have excellent sq and the tweeter is perfect!

good sound at great price.

January 5, 2012

These speakers have good bass but the tweeters are somewhat harsh. They only bothered me a few times but got better after break in. I was feeding them 300w each and they took it like a champ. They look like some well built speakers. I will probably end up buying them again when i do another build. my only real complaint is that they do not have a BIamp option, but most components do not have that option.

Good sound and value

May 3, 2010

I've installed this set in my Nissan 370Z after being very disappointed with the factory sound set up. For those interested these speakers are run off an Eclipse AVN62D headunit and being powered by a Boston Acoustics GT2125 amp putting out 125 wts RMS each at 4 ohms. These speakers scream! Very clear sound up to the point where my ears hurt. I have the crossovers set at the +5 setting for the highest highs as I like my treble to be very crisp (I have two huge subs in the hatch to cover the rest) and the sound is very clean. The mids kick out a very nice amount of bass - somewhat comparable to a high output 8" sub - and fill out the range very well. I think for an average consumer this set up with a powerfull 8" or a good 10-12" sub would create a very admirable system worthy of compliments from anyone. One thing to note - the tweeters are dome shaped. Was hard for me to tell in the pictures. This required me to make a custom bracket to mount them lower in my dash so the stock grill would cover them. But, it also allowed me to angle them directly to the center point between the driver and passenger for optimal sound. For me, this was worth the investment and money well spent.

Outstanding clarity at high levels and durability.

April 1, 2010

I have these installed in my 2003 Cobra as well as my brothers 2003 Chevy 1500 Sierra. In both vehicles they're powered by Infinty amps (the reference 475a and the Kappa 4 channel) and both sets sound AMAZING. The x-overs have adjustable volume settings for the tweeters which enables you to set it the way you like based on their distance and mounting options and the mids are smooth and clear with no distortion or image fouling at even high volumes. I ended up putting CDT's in my other truck and I'm starting to think I made a big mistake, I should have stuck with what I knew and got these again. The only option I'd like to see with these is the ability to add an extra image tweeter to the X-over, but then again only CDT has that option right now so I guess I'm asking for a little much.

Infinity Perfect 6.1

July 30, 2009

I recently purchased these speakers and i was very disapointed in the crossovers. I disagree with the frequncy they r being crossed at. I installed them with a different set of crossovers and the clarity of these speakers is what i have been looking for. Great sound at all ranges and after i tuned them i was blown away by their performance. I highly recommend these. (Buy an adjustable crossover with them)

Oustanding longevity and Performance

January 21, 2009

I have owned these speakers along with their 6x9 counterparts for at least five years now. I ended up blowing one of the 6's due to a wiring issue. I have to say these speakers are absolutely the best sounding and best quality for the money. Still to this day the speakers have great highs and a solid mid-range. I think my car will end up dying before the speakers. Overall I am very satisfied with the speakers. I would recommend these to anyone who truly appreciates music. If you are looking for just bass don't buy these. If you want to hear your music for the first time all over again, these are the speakers for you.

By far the best speakers I have ever owned. I install car audio for B*** B** and hear different speakers in all kinds of cars every day but these are by far the best speakers I have ever worked with on a realistic budget. I would recommend to anyone who wants an amazing sound, just be sure you have a good amp behind it.

Best speakers I've ever heard.

July 13, 2007

These are literally the best soundinding speakers ever. They can hit any note, high or low. The bass is amazing. I thought my subwoofer was on when I first listened to them. They never distort no matter how much I tun them up, and I am feeding them their rated 100 watts. Only problem is the crossovers are a little big.
