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.
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 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.
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.

Silk
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.
Glass Fiber
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.
Butyl 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.
500 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.
120 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).
65 - 20,000 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.

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.
2-15/16"
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
3-5/16"
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.
5-3/4" x 5-3/4" 
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

Killer sounds

February 20, 2013

Ive had the speakers in the front doors/dash in stock locations in my 05 xterra for a few months now, and after they've broken in Ive become more and more impressed. Ive been running them off of a SKAR audio SK85.4 (85 watts rms per channel) and am using the supplied crossovers. They are begging for more power.

Mids
the motor structure on the mids is really impressive, and is just about the size of the cutout to mount the speaker (I had to make 1.5inch thick rings to be able to roll down my windows). These things are absolutely capable of some midbass if you have a decent install (my doors are deadened with murdermat bl on outer skins and deadened/sealed with it on inner skins). They will even pick up some of the bass notes from my decaf mixes (if you dont know who this is and you like bass, look him up on youtube and get his zips, you will thank me later). If i felt like glassing up some kicks, theyd probably dig even deeper.

Tweets
alot of people say the tweeters are super bright. I actually quite like them, while i could see where many people would feel they are over the top, this is not a high end SQ setup by any means, and is more intended to be a loud set for SPL inclined systems. I just bumped them down 2db @ 8khz on my H/U and called it a day.

Summary, if you want a killer set of comps with great output, and that sound great doing it, pick up a pair of these massive rk6s and I doubt youll be disappointed.

SPL not SQ

June 30, 2012

I bought these speakers based on some other reviews on them thinking they would be my all in one solution for my car and require me not to need a sub. Boy was that wrong. Reviews had indicated these were very bassy and overall pretty good speakers. I installed these and was immediately disappointed. No bass response and crazy ear bleeding highs. The woofer seemed mismatched from the tweeters by an amazing amount. In an email with Massive they informed me that these speakers are mainly designed for high SPL situations. They did however offer a solution to tame the tweeters. Unsolder some components from the crossover and install a L-pad resistor network to result in 11dB attenuation on the tweeters. At the current moment I chose a attenuation L-pad network resulting in 6dB of attenuation and I am using my Kenwood X996 to further attenuate 8dB after 2.5khz. This seemed to really help and I am pretty happy with them as they sit. I notice the low end really starts to die off around 90hz. I have fixed my low end issue by adding a sub. What I can say nice about these is they have a very strong mid range and that is something I typically not used to so it took a little adjusting. They seem pretty detailed in the sound they produce. They also are very sensitive speakers so they dont need much power to get really loud.
