Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
S2 (Cadence)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
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.
1000 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.
500 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.
2"
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 - 500 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".
83 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.
12.5 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.
Woven Fiber Pressed Paper Cone
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.
Foam
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Double Stacked
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.

06 Ram 1500 laramie upward firing at 1.5 ohm in a sealed 1.3cu ft enclosure under rear seat seat with a 500 rms amp. Subs have good base production with accuracy. Full excursion generates high spl levels and no bad roll off. From 25-55 hertz the performance is more than good. Price is good for a quality sub.

High Quality Sub For Minimal Cash

March 13, 2017

I purchased this sub for my Miata project car after going through JL, Alpine & Precision Power subs. Those previous subs have all been powered by the same Alpine mrv-500 (going from memory, it's 300x1 @ 4 ohm) amp.

For reference, the rest of the system is a RetroSound head, Alpine mrv-300 (50x4 @ 4 ohm), Alpine mrv-500 (300x1 @ 4 ohm). 4 channel amp pushing Morel Maximo coaxials in doors & (cheapo) Pyle mid bass behind seats. The sub amp is obviously powering this sub. The car has RaamMat through the entire interior & doors. I normally listen to old school rap, trap, edm, alt rock/grunge, and classic rock normally - emphasis on rap & trap music though. My daily driver GT86 has the factory upgraded BeSpoke stereo with a Precision Power sub & Precision Power amp (for sub).

I have had a 5 channel Cadence amp & Cadence components in a previous daily driver VW GTI & was impressed, so after I had blown through the other subs, I thought I'd give the Cadence one a try. The enclosure is about .45 cuft sealed. I have installed it for about 3 weeks & have about 4-5 hours (at most) on the sub, so it's not totally "broken in" yet.

I can safely say at this point it sounds much better than all the other subs I have had. The lows (approx under 60 hz) are deep and unmuffled, and it hits very accurate. I set the crossover point at about 110 hz. The sub has a pretty big excursion & although you can have the sub in a small sealed enclosure as I have, I have a feeling it would really shine in a slightly larger (.75 cuft) ported enclosure. Even how I have it - I have zero complaints. Cadence provides excellent paperwork & graphs outlining performance expectations given the different enclosure types - something I wish all manufacturers did.

If I could change anything about this sub, it would be that I wish there was some sort of grille/protection for it. It comes with a trim ring, but I have to be mindful what I put in my trunk so as not to harm the sub. Also I'm not a fan of the "badge" on the cone of the sub, it makes it look "cheap" - but aesthetics's are objective I suppose.

Overall, so far it's literally one of the best value for subs I have ever had in the 25 years of my tinkering with car audio (and well over 30 different subs). This is very high praise. I would put Cadence equipment up there with the best, most respected names in car audio & not think twice.
