Customization with Boston Acoustics G3 Subwoofers

Boston Acoustics' G3 series subwoofers provide deep, crisp, responsive, and quality bass that has come to be expected from a high-end company like Boston Acoustics at an affordable price. Featuring Soft Part System (SPS™) technology that will allow the removal of soft parts in case of an impedance change when adding more subs, repair if the voice coil fails and is damaged, and it also allows for customization by allowing the basket and back screen to be removed from the motor structure. This will then allow the option to paint, chrome, or even powder coat to make your subwoofer really stand out. G3 series subwoofer also feature SureSet™ impedance selection that makes wiring easy and accurate as well as adds protection from overdrive to the voice-coil, and a RadialVent® cooling system that decreases heat dissipation as well as distortion cause by thermal discharge. This improves the subwoofer's ability to perform at higher power handling levels while still producing quality bass output. G3 series subwoofers are versatile, dependable, loud, and affordable making them an easy selection for any car audio system.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
G3 (Boston Acoustics)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
10"
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.
375 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.
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).
24 - 350 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".
87.3 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.
14.5 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.
Copolymer
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.
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.
0.5 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.
0.5 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.
1.3 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.
1.3 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.
6-3/8"
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.
9-1/4"
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.

Wow...What a great little sub for the money and really worth alot more !.... I have 1 of these in a ported box in the trunk of my crown Vic...and I compete for SQ with MECA and Ive won 2 first places with this little guy taking care of all the lows. When I want to tune for bass ...it Kicks pretty dang hard ...I've hit 132.2 decibels... not too shabby for such an inexpensive sub. Oh yeah ...and Im only throwing 300W at it !!! I'm powering it off the sub channel of an Alpine 5 channel digital Amp ... PDX-5 ... Totally satisfied customer here ...everything Ive ever bought from Sonic Electronix has been a good deal ...they have the best prices and everything is perfect when it arrives here. Thanks Sonic E !!!

I bought this sub and put it in a 0.5" cu ft sealed box, as per manufacturer's spec, and it sounds amazing in the back of my '97 tahoe, no joke. I'm using this with Alpine SPX-13PRO on a Hifonics ZXI-6410 amp. First and foremost, this sub sounds VERY good! I have to be honest, this is my first car sub, but I've been listening to high end headphones for a couple of years now so I know what good sound sounds like, and this sub is it! You can feel the scratchy growl of a bass guitar reverberate in your ears, easily distinct from the dull thud and pulsing impact of every bass drum hit. This sub provides sound that is thick, textured, and layered, without a hint of distortion. With the gain turned up to about half for the sub, and with good EQ'ing, the sound is very satisfying at 0db, and in fact on many songs I feel there is a bit too much bass for my musical tastes and turn it down to -2db. on some songs, the car rattles with the sub at 0db on the head unit, which goes up to +10db, so...yeah. I couldn't imagine it in a ported box. or two...which I might be doing soon (long story).

SQ winner!!!

December 26, 2010

It's not going to win any competitions based on volume output but no one is making a sub that can accurately reproduce bass with as much clarity as the G3. I have tried them all and it's very easy to be fooled by loud woofers versus quality sound. Also, it's amazing that such a high performer can only require a sealed enclosure at .5cu ft which is usually never enough despite what the manufacturer states. This thing is fully operational and humming beautifully with that setup. I'm throwing at least 400w/rms at it and it's handling it without breaking a sweat so stop looking at all these "loud" subs and get to buying the far superior G3. Heck, you can replace the parts and it comes with a built in fuse so you never burn out your sub for cryin' out loud! What are you waiting for?

Great Sub!!!!!

March 25, 2010

This sub sounds awesome. It is loud enough to pound with rap or hip hop music, but tight enough to sound great when your jamming to some rock music. It is definitely one of the better subs I have ever heard. You can't beat it for the price!

Awsome Subs!!

February 15, 2010

These subs are amazing! I have two of these in a bassworx box running on a 1200 watt amp and these things pound! its some of cleanest bass Ive ever heard, and it blows my friends subs away. I definitely recommend these subs for the price. Oh and the rms rating is way under rated
