The Extremely Versatile SWS Subwoofers

The SWS-6.5 by Earthquake Sound features a mounting depth of 1-3/4". With a depth this small the applications for this woofer are endless. This shallow-woofer-system series subwoofer is perfect for those with limited space but that still want some bass in their car. The woofer features a light weight resistant PVC cone and a long-lasting UV treated high-roll composite foam surround for added rigidity, stiffness, longevity and increase power output and performance. The woofer is so small that it does not require an enclosure and works perfectly as a free-air woofer. Don't let the size of the woofer fool you into thinking it's not powerful, with an Xmax linear excursion of 15mm this woofer will hit low-frequencies with accuracy and precision for a clean, crisp, and responsive bass reproduction. Although often imitated the SWS's 3 protected U.S patents assure that it's never duplicated. If you have 2" of space to spare then there is no other option than the SWS series subwoofer.

Where Should I Install the SWS Subwoofer?

Earthquake SWS subwoofers are designed to be installed in areas with limited space. This makes them ideal for truck cabs and under seats. As noted in the diagram below, these subwoofers are perfect for installing underneath the front seats, under the rear seats, or behind the rear seats.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
SWS (Earthquake)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
6.5"
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.
200 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.
100 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.
Single
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.
1"
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".
77.3 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.
15.00 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.
Polyvinyl Chloride (PVC)
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.
UV Treated Foam
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

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.
1-3/4"
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.
5-3/4"
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.

Yes

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.
39.31 Hz
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.
9.94 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.
1.221
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.
1.723
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.
3.600 ohms
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.

Easy Fit

September 28, 2011

After looking for a replacement sub for the center console on my 2006 Jeep Wrangler, I selected this and wow, what an easy installation it was. No modification. The original has a dual voice coil with 2 sets of wires, taped a pair and just used one set and that's it. the sound is far better than stock. Eventhough they come in pairs, no problem...sold the other to another Jeep owner who heard mine.

SWS-6.5 review

June 15, 2012

I purchased this product due to extremely Limited space in my Roadster. at 1 3/4" mounting this provided me with enough room to extend my seats far enough. If you are expecting the punch that a 10" or even an 8" would deliver than this is not the product for you. If you need just a little bottom end response these will help. I wouldn't class them as subwoofers, more bass and even Mid Bass drivers. Again if you really want the sub bass response and have limited space go with shallow 8" Pioneer or the 8" SWS.

Good subwoofer

February 23, 2012

I use this subwoofer in a small box. It's very thin and suitable for a small space. And the bass impact is very impressive.

BETTER THAN I THOUGHT!!!!

September 27, 2011

I bought these subwoofers because I wanted them in the sail panels in my 95 Pontiac Firebird. They are nice sounding!! You would expect distortion with higher volumes but you wont because these subwoofers sound just great! They fit with no problem and they sound real good. They work well with stock amplifier but with an aftermarket amp you won't be displeased. I finally have bass in my car these speakers actually hit lows....I didn't believe it at first until I found a song that has more lows and wow...they are actually real good. I recommend these speakers for anyone who wants bass in their car without having all the shaking all over.
