Speaker Specifications

This is the manufacturer product line of speakers.
Kappa (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.
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.
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 Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.

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.
Carbon Composite
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.
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.
270 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.
90 watts
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".
93 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).
45 - 35000 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.
2 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-1/8" x 5-1/8" 
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.

Incredible Speakers

October 12, 2013

I currently have a set of 6.5 Kappa 60.11cs wired up to a Kenwood 4ch amp getting about 90w RMS, HOLY SMOKES! these speakers get LOUD and amazingly Clear! I will be installing the 5.25 Kappa components in the kick panels soon and could not be more excited to have a full range of sound. people say when they install a quality set of speakers they hear notes that they have never heard before, and now i get to say the same thing. put on some Stevie Ray Vaughn and hear EVERY note. and lets talk about loudness, cranked it 3/4 way up and walked away from the truck with the windows down and doors closed... Clean and Crisp sound can be heard 150+ ft away. Would recommend these speakers hands down,

Great speakers

August 17, 2014

I recently bought these speakers about a month ago. I own a Mitsubishi 3000gt and it has a small interior. My goal was to get really great front speakers since it is a coupe. These speakers are a huge step up from stock speakers and 100 an under aftermarket speakers. What can I say? these speakers provide incredible sound but barely met my expectations for speakers within this price range. Like any component speaker, the high and low frequencies are divided very well by the crossover. The speakers are very loud for their size as well. I am running a kenwood kdc x397 unit with a 100 W max / 55 W rms amplifier. I love the high and mids that the speakers produce but they do lack on bass. At around 60 - 70 % volume the bass reaches its max and distorts a bit. Im running some Pioneer TS-A6975 6x9s in the back. The 6x9 are decent speakers that are very loud and produce great bass; They are my main source of bass in my car. I love these speakers and combined with songs that have great sound quality, not downloaded and converted from youtube, they produce amazing sound. I would recommend these to anyone looking for speakers with great high and mid frequencies.

I have 2 pairs of these installed in a 2015 Toyota Tacoma and they sound crisp, clear, and loud. I have the cross-over on the Kenwood head unit set to 100hz and are driving them with a 4 channel Polk Audio amplifier. Very bang for the buck, well designed and engineered.

These are replacing the stock 2ohm 6x9 in my beats by dre system in my 2014 dodge charger.
Rodney M on Mar 1, 2015
I thought they would be good but I found out that they only perform the way they should if you have a sq build. Wouldn't recommend for a loud or spl system.
Adolfo A on Aug 24, 2015
I chose these components because they are one of the best components out there. I have been looking at them for quite some time. Sonic threw in the price drop and I was hooked.

hello im really struggling on wat 4 channel amp to get? one that i could run this and two other kappa speakers for rear havent got them yet but will as soon can get help choosing a good amp or best any suggestions?(rear will not be coponet speakers)
melissa a on May 4, 2016
Best Answer: I don't normally power my rear speakers with an amp as I prefer them to be used solely for rear fill, but if you're working with a large interior or you just really want to amplify the rears; the JL JX400 is a great choice for a tight budget. I run my front components off of the JX200 and my rear coax' directly off of the deck. If you have the room in your budget, the JL Slash series amps are among the best amps available in their price range and the XD400 isn't far behind it.

Best Answer: Hi Erik,

Please elaborate, as we get the feeling that we don't understand the question. There is only one way, straight to the amp. Below is a copy of the manual, which illustrates the wiring.
