Speaker Specifications

This is the manufacturer product line of speakers.
KS (Kicker)
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.
6-3/4" (Oversized 6-1/2")
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.
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.
250 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.
125 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".
91 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).
35 - 21000 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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
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.

Very good speakers, nitpicks only for downsides

June 10, 2014

I got these after realizing that I was pushing the JBL GTO628s too hard with my amp and needed more power handling. I did a lot of shopping and almost got the Polks but I wanted enough power handling to be bullet proof with my amp and I have Kicker 6.5" subs in the back holes so figured I might as well stick with one brand. I was hesitant due to the higher price and my underwhelming experience with the lower end Kicker coax speakers I listened to in a retail store. I do not regret my choice however.

I'm driving them through a Pioneer GM-D8604 being fed by a Pioneer MVH-X560BT head.

First the one real down side: The crossover is huge. I still found room in the doors of my 2000 Corvette, but they were much larger than I expected. Good news, they don't look like they'll be failing anytime soon. Beefy is a good adjective. Only other niggles, documentation could be a little better, crimp on connectors for the crossover would be nice addition to the package.

The look great, they're convertibles, so you can use them as coaxial speakers if you want, the power handling is fantastic, and they sound amazing. I had to modify the Metra adapter for my Corvette doors because it was a 6.5" hole and these take advantage of every bit of room they can find in the 6.75" package. I used a drum sander to open the mounts up a little and they work great. They did a great job of maximizing speaker area and it shows in the low range. It also keeps the installation depth quite shallow. They even have a channel in the back if you run it as a coax so that the wires don't stick out past the magnet.

I mounted the tweeters with the angled bezel in the door adapters as well and the staging of the highs is great. The silk dome tweeters aren't harsh or directional like a lot of less expensive tweeters. With the coax JBLs the highers were much more directional. 4x the price, you expect better.

All in all, great speaker, handle lots of power, flat through a very wide range, including some decent bass. Paired with the CVT65s in the back I'm extremely happy with the sound. I don't have booming lows but there's plenty of tight punch. It's no heavier than the blose system I removed and I didn't give up any storage space.

Bottom line: Be nice if they were cheaper and the crossover more compact, but I don't think you can find anything that compares for the price point with this much power handling.
