Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
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.
1200 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.
600 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.
2 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).
29 - 300 Hz
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".
94 dB
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.
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.
Butyl 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
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.
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.
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.
10-3/4"
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.

Great Subwoofer.

May 28, 2010

These subwoofers blew me away.I'm running 4 of these subwoofers to a Soundstream Rubicon 2500 watt RMS mono amplifier. They handle every bit of that amp and sound perfect doing it. I'm a M.E.C.P. installer and I never heard a subwoofer at this price sound this good. The old Phoenix Gold I use to know is back in a big way and Thank SonicElectronix for all your help and great prices.

Excellent sound quality and top notch service

February 23, 2010

Well I ordered this RSDC after hearing a lot of great things about it and all were true. This subs sound quality and accuracy rivals any focal or sub under 400 dollars. Ive owned so many different woofers and the RSDC along with the JBL GTi series are the best ive heard for SQ. This sub is geared toward sound quality but will rattle your teeth if installed correctly of course and this sub is very efficient so if you only have 300rms it will still do the job. Another thing I like about the sub is that you dont need to build a giant box for it, they are meant for smaller sealed enclosures but also do well ported. Also if you are on a tighter budget the RSD subs are great and blow away every other sub in the price range. I here a lot of guys posting reviews on here about different subs and them not being happy about the output and 9/10 times it because they are running a boss, power acoustik, pyle, or cheap non CEA certified amp. An amp is very important in powering your sub. For example, most of the cheap brands are going to rate way high watt numbers but if they are not CEA certified then there's no telling what the true wattage is. also a boss or power acoustik amp is going to be far less efficient so you can expect more light dimming and power drawn for your alt, Anyways if your looking into this sub buy it and you wont regret it.

Excellent sub!

May 29, 2010

I installed a pair of these for a friend. They were powered by a Hifonics HFi1000D (bought on SE), wired to 1ohm in a sealed 2.75cuft enclosure. He wanted SQL, he got it! These subs handled everything the Hifonics threw at them, they can probably handle more. The bad was very tight and hard hitting. On the SQ side, with a little tuning, they sound excellent. With a flip of the phase, they blended perfectly with the mids and played up front with a very convincing presence. I was very impressed with the build quality of these subs. The cast baskets are very nicely built and designed. The RSDc have a nice looking cone, if weren't for the silly looking wrap around gasket, they would look perfect. I ended up removing the gasket and magnet boot. Overall, I was ecstatic with the results, they get the job done and then some. I would recommend them to almost anyone.

Good Sub... Great Price!

February 1, 2010

Let it be noted that I rarely use this sub to it's full potential. I usually listen to Rock/Metal music so I usually have the bass set pretty low. However, when I do crank the bass up for Rap or any song with good bass the sub hits very well! At low levels of bass the sub does rumble but puts out a very pleasing thump. The set up I am using is one RSdC122 12" with the Phoenix Gold V8001 Class D Mono Block Amp in a ported box with a 1 farad phoenix gold power cap. I am very pleased with this system and was even more pleased with the price. If your looking for a true competition sub this probably isn't it but overall this is a good sounding sub for an awesome price.

SPL Monster!

August 24, 2009

I just purchased two of these subs. I am running them on a SPL 3000 watt class d amp wired at 2ohms. I have had many subwoofers over the last decade and these subs really impress me. The sound quality is amazing, the SPL levels that these subs can reach is nothing short of outstanding. Don't be deterred by the 600 watt rms rating, these subs are capable of handling much more than that. If your looking for a good quality well built bass monster these subs are for you.
