Massive Audio at A Minimal Price

These ultra-responsive speakers by Massive are audiophile quality at a tiny price. These high-powered speakers can be mounted as a component system, or even co-axially with the included hardware. The 28mm Silk Dome tweeter has a 3-stage level adjustment so you can choose how you want to hear your music. The durable cast aluminum basket will dampen almost all resonance for a crisp, non-cancelling sound that will not fatigue your ears. The efficient neodymium tweeter magnet provides ultra responsive music that blends great with the 6-1/2" mid-woofer. The 18db external crossover will roll off the frequencies that these speakers cannot physically produce, for ensured durability and long life of both speakers drivers. Try Massive Audio today, and you will be surprised at the quality you get for the small price you pay.

Speaker Specifications

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.
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.
Soft 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.

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 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.
280 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.
130 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".
89.9 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).
20 - 22000 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.
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.
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.
5-1/2" x 5-1/2" 
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.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Way underrated speaker!

July 20, 2012

I actually own 2 sets of the CK6 and a set of the CK6.9 and are great speakers (SQ) for the price! After reading great reviews on these everywhere, I looked I decided they met my needs for budget wise for my SQ project. Couldn't be happier they have lived up to their reviews! Would recemmend them to anyone looking for a nice set of SQ speakers, but don't have the thousands to spend! Awesome comps, great value, just make sure you have the power to throw at them and you'll be pleased with their performance!

AWESOME!!! Compared side by side with boston pro audio's!

June 27, 2012

I own a set of these and they are great. I have previously had rockford power t1 6.5" , image dynamics CTX6.5 , Old school Boston Pro Audio and some new CDT 6.5" components all have been on the same head unit (kenwood 25th anniversary) same car and same amp( kicker zx700.5 bridged to 150 watss rms x2). All i can say is wow the only ones i would compare these to in my arsenal is the boston pro's. And even then its close. The factory ck6 crossovers even on the -3db setting for the tweeters are harsh. The boston are a little more dynamic but these are still good. The build and feel of these are great i currently now run them acftive on 125watts RMS x 4 and they are great. I properly tuned the amp and guessed on the EQ i am running a 250 amp alt and have 0 gauge for the amp so if they are fed clean power at all times they show no fatigue no distortion even on my previous 10 hr road trip. I would reccommend these to anyone and everyone i will be purchasing another set.

Awesome system

November 21, 2011

These speakers have far surpassed what I ever would have expected. There is actual bass, and clean bass at that. For many people you might not even need a sub, the balance is already very good. The tweeters are magical. They're big, deep, and robust. They reach down low in frequency response, and they've been crossed over low as well, so when they're mounted up on the door or A pillars (as in my install) it really brings the soundstage up. So much so that I pulled the center speaker in my car, it wasn't needed with these speakers. The tweeters are a little strong at 0db on the crossover, but there's a -3 setting as well. The most surprising thing is how well they perform with just the factory head unit in my '11 Regal. Once I get them hooked up to my amp I expect them to perform better still. Even at double the price these are going for they would easily be worth it for the sound they produce. I can't recommend them enough.

Cottonwood, AZ


December 7, 2011

These speakers are awesome! The midbass is fantastic, and the overall sound is very even and realistic. The tweeters can be slightly harsh at first, but that seems to go away quickly after being played for a little bit. The tweeters can be set at +3Db, 0Db, or at -3Db - mine are at -3. I have 145 watts RMS going to these speakers, and they take it and play very loud and clear without any problems. Like I said before, these sound very realistic without any significant peaks/dips in the frequency response - at least nothing that I noticed. My deck has an EQ on it, and I have it set almost completely flat! The only deviance from flat is one notch down and 2.5kHz, and one notch down at 8kHz. I honestly think you cant go wrong with these speakers, and at this price it's just a fantastic deal. Do yourself a favor and stop searching and BUY THESE SPEAKERS NOW!!
