A Distinguished Look with Cerwin-Vega's VEGA Series Subwoofers

When you look at the VEGA124.2 and see a bright red rubber surround, you instantly know it can only be the infamous Cerwin-Vega VEGA series subwoofer. The VEGA series subwoofers are the most recognizable Cerwin-Vega subwoofers and are available in an 8", 10", 12" and 15" size woofer. With each size having the option of either a Dual 2 ohm or Dual 4 ohm voice coil. With this many available sizes and different voice coil impedance the possibilities are endless and the VEGA series subwoofers are sure to satisfy any bass reproduction need. VEGA woofers have a power rating of 500 watts peak and 250 watts of continuous RMS power. The woofers feature a composite polypropylene design that offers perfect weight to strength ratio to increase the durability of the subwoofers and improve performance. Its rubber surround allows for high amounts of excursion, while the rolled aluminum former increase thermal capabilities to improve power handling. The woofers also feature cross-flow window venting that reduces voice coil temperatures and radial contact convex domes that reduce cone flex and minimize distortion. The VEGA series subwoofers really are the "face" of Cerwin-Vega and for this reason have been designed and manufactured to reproducing rich, full and tight bass for any type of music and in any type of vehicle.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
VEGA (Cerwin-Vega)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
250 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
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
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
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).
Not specified by manufacturer
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".
84.7 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
4.30 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
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.
Composite Polypropylene Cone (CPPC)
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
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.25 cubic feet
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.25 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.50 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.50 cubic feet
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.
6-1/4"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
11"
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

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 10.
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 10.
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

January 2, 2012

These subwoofers are the first subwoofers that I ever purchased 2 years ago. I put 3 of them connected to an arc amp and around 700 rms bridged in individual sealed boxes. They hit pretty damn hard and made my car rattle so loud that I thought something was wrong with the subwoofers when I bumped it real loud. A year later I got a custom ported box tuned to 32 Hz built by DAVE THE BOX GUY shipped to me. Now it Bumps so much more, sounds so much cleaner, flexes my entire car. If i put a fistful of change on the top of my car and it JINGLE JINGLE JINGLES till it jumps onto the ground. Now i'm telling the truth here, A policemen from a Different town knocked on my door and said that if I were to be caught bumping in town that I would be arrested and fined. Kind of scary but a good sign showing i'm bumping loud. These subs are still working 2 years after I have bought them. They have somehow survived the constant abuse from me- an amateur. for example Tuning the amp by ear with no knowledge of how to tune an amp. I have read doing that can ruin a setup really quick. These subs are very inexpensive and easy to power. GET A GOOD BOX FOR THEM ITS CRUCIAL! Sonic Electronix helped me out EVERY step of the way. You will always have someone to help you when you call, weather you have or have not yet boughten anything. 5/5 for Sonic and the business they conduct.

pretty good subs

June 6, 2012

i have had two of these subs for seven months now and i started with a sealed box and i was not very impressed. i bought a 70$ ported box here on sonic and wow, these will actually hit hard. i have them hooked up to a 1000W amp. if you are looking for lots of bass i would not suggest these, if you are looking for a fair amount of bass and it be clean, i would suggest these subs with a ported/vented box. make sure you hook these up to a high quality amp!

didnt last long

April 30, 2012

I hooked this up to an MTX Road Thunder 250 Mono amp on a 2ohm load, it hit hard dang hard in a sealed box. Then a week later it quit. I guess MTX was too much for it. Gonna try a diffrent sub this time.

GREAT SUBS!!!!

March 27, 2012

I have 2 of these subs and there great!!! Both are in a "sealed box" wired up to 400watts RMS. They definately can take power....there hooked up to a RE Audio 2ch. amp and I don't think its enough power (it is...I just think they can handle more)! Would recommend these with a mono amp (precision power-class D) and you'll get more bang for your buck!!! Overall rating...10 out of 10....great price...great sound and great quality!!!

These cerwin vega 12s hit so hard WOW!!

March 21, 2012

I got two of these 12s with the enclosed box and the RE Audio XT 800 2.v3 and they hit like a big hammer. These 12s are built 2 last for a long time under a lot of power, witch the RE Audio amp puts out. You need to pick these Cerwin-Vega 12s up now!

They Sound Great

March 16, 2012

I purchased the kit with two of these and a RE Audio Amp 800W max and I believe 400W RMS bridged and they really do slam! Can't beat the value! There in a sealed inclosure at the moment, I want to try a ported box sooner or later.
