Priced Per Pair

Speaker Specifications

Series
This is the manufacturer product line of speakers.
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.
5-1/4"
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
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.
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".
89 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).
80 - 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
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.
2-7/16"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4-11/16"
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.

A little pricey, but well worth the money.

September 18, 2011

At first I wasn't sure they would be worth it but after hearing them I was glad I bought them. They create amazing special sounds. They can be accommodated in almost any enclosure and always sound amazing.

Great little speakers

April 16, 2009

Great speakers for anyone that is aiming for clarity (even at high volume levels). When they say 80-23k Hz they mean that these speakers can punch you in the ear drum with their highs. The highs on these speakers will be described as very bright or even harsh to some. The crossover is comes with does have a -4db setting which evens them out fairly well. This being the case I would strongly recommend listening to them before you complete the re-paneling of your doors. Keep in mind that these were designed with crisp highs in mind. The lower mid range in these speakers is nearly non-existent. With heavy EQ modification they can produce accurate lower mid range, but not at any serious volume (think laptop loud) without driving them into clipping. If you listen to rock you will likely want to supplement these with a set of 6.5" or 6 x 9" speakers with solid lower mid range even if you have one to two 10's or 12's. If you're running 8's it might be alright. If you only have two speakers in your vehicle these probably wont be the speakers you want. The above may sound like strong negatives. I didn't intend this review to be negative what-so-ever. Every speaker has an intended use and these strongly deliver what they were intended for -crisp, clean, and loud upper mids and highs. My only complaint would be the size of the crossover. It was intentionally designed to be much larger than it really needed to be. Being that I bought these knowing how big it was, I can't really count it against them.. This intent fits my system perfectly so I'm giving them 5's across the board.

specifications are good

June 9, 2006

I won a 93 corolla, and i am looking for component speakers going in to my front doors and i came accross these which are of same size as my front speakers. As I have gone through the specification for the speakers I find them to be good, best but a bit expensive, but worth for real music lovers.

WoW!

November 2, 2005

I bought these speakers for my front doors on my 95' Monte Carlo, and I couldn't be more impressed. The sound quality on every pair of Infinity speakers, especially these ones, has always astounded me. If you are obsessed with car audio, and have a spot for a large crossover you need to get a pair of these!
