True 4 Ohm Impedance

These speakers are specially designed with true 4ohm technology. The impedance of these speakers are 3ohms, but when you pair them with thin factory wiring, the impedance will naturally rise up to a true 4ohms resulting in a maximum amount of power draw from your 4ohm rated factory receiver, aftermarket deck, or external amplifier. What it comes down to is efficiency. If you need a speaker that will get the most out of your current sound system, the Reference X series is for you.

Plus One Cone Technology

Each of the Reference X speakers features plus one woofer cone technology. This means the cone has been designed to be slightly larger than comparable speakers, giving you even more output on the same amount of power. This drastically increases the efficiency of the speaker, and also extends the frequency response even lower to give you that nice thump you’ve been looking for.

The Reference of Audio

Want an easy upgrade for your factory speakers without going over your budget? The Infinity Reference X Series is for you. Its engineered to bring your factory audio system to life, or to add clarity and depth to an aftermarket system. With innovative, patented technologies, and the kind of premium quality and construction that you would expect from the worlds top-selling premium car speaker brand, Infinity Reference X speakers will transform your listening experience into something amazing.

Priced Per Pair

Speaker Specifications

Series
This is the manufacturer product line of speakers.
Reference-X (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
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.
Dome
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
1"
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.

Textile
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.
Polypropylene
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.
180 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.
60 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".
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).
53 - 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.
3 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.

No
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.
2-1/16"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-1/16" x 5-1/16" 
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.
Yes

Phenomenal Speakers!

November 14, 2013

I have 4 of the 6-1/2" Infinity REF-6502ix speakers in my 98 Dodge Dakota. They do a great job in my opinion of projecting both high and low notes. I listen to Hip Hop/R&B music with a lot of bass. These speakers hold up to a lot of bass even with the music turned up loud. However I have found that the speakers do distort after listen to music loudly with a lot of bass after a prolonged amount of time.

Smooth sounding

September 17, 2013

I needed a speaker with a tweeter that can pivot. Also I like to listen to music without hearing distortion, this speaker is perfect. If you like to listen to rock, classical songs with vocals this is the perfect speakers. These speakers play very accurately and that is important to me. I highly recommend them to anyone who like audiophile grade in the car. Don't purchase these speakers if you don't plan to play them with an amp because you won't get the full performance out of them just playing them through a receiver.

Infinity REF-6502ix

March 5, 2013

These are really good speakers as long as you have something to push the bass. These speakers dont have that much bass but have really fantastic highs and mids. I had 5 1/4 alpine speakers and now that i have these i can hear the vocals and everything else over the bass from my 2 12s. Plus the speaker grilles look really nice even though i dont have them on my speakers due to space restraints
