Getting started with Boston Acoustics's G1 Series

G112-44 subwoofers are perfect when looking for a comfortable amount of bass. The dual 4 ohm voice coil will allow you to run one sub at 2 ohms or a pair of subs at 4 ohms or 1 ohm giving a tremendous amount of versatility and thus making them ideal for any set up.

Boston Acoustics is well known for their amazing quality and products in the home audio world. Their dedication to quality and performance is seen in all of their products, including the G1 series subwoofers. Available in an 8", 10", and 12" size woofer along with the option of either a single 4 ohm voice coil or dual 4 ohm voice coil for multiple wiring options that better suits your personal needs. All G1 series subwoofers are equipped with Boston Acoustics specific technologies such as SureSet™ impedance selection that makes wiring easy and accurate as well as adds protection from overdrive to the voice-coil. G1 subs also feature a RadialVent® cooling system that decreases heat dissipation as well as distortion cause by thermal discharge. This improved the subwoofers ability to perform at higher power handling levels while still producing quality bass output. All G1 series subwoofer feature a co-polymer woofer cone and foam surround for rigidity and increased excursion. So if you are looking for entry-level bass from a product that will still deliver high quality performance, the G1 series subwoofers are the perfect match at a competitive price.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
G1
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
200 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).
20 - 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".
94 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.
10.5 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
Silver
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.
1.0 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.
1.0 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.
2.0 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.
2.0 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.
5"
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.
11-3/16"
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.

sound quality

September 25, 2012

I try almost all kinds of subs from kicker, rockford t2, orion, alpine type r, etc. I buy this sub just for temporary cuz i blow my sub t2 and i play all the same music in my usb its not that loud but its big change in sound quality. I under estimate this sub this is under rated for 200rms now i still buy different sub for my experiment. This sub im sure much better d g2 and g3 or maybee g5 buy this and use a 500 rms amp for this.

Great Subs

February 20, 2012

I have owned these subs for just over a year now and they are great. I got mine before the price hike and for what i paid I was ready to order 2 more. Since my trunk is already low on space I dont see a need for 4 12s in a 95 honda accord when 2 get the job done. The only thing is the sponge around the speaker cone has little cuts from me putting stuff in the trunk moving back and fourth from school. Overall these are a great sub and when I bought them there was no way you were getting better at the same price.

Good solid driver

February 6, 2011

I use it as a sub-woofer for my home stereo system. We wired it up in a dual-voice coil configuration. Solid base without a big unwanted boomy peak. It would be nice if this configuration was documented somewhere. My son purchased one a year earlier and I liked his so much I purchased one too. It made a noticeable difference in how my speaker system sounds. Much better.

Good sub

December 1, 2010

This sub sounds good. Doesn't need a lot of power to sound good. I have mine in a sealed box built to proper specs. I own a extended cab Frontier and it fills it with good sounding bass

Great Sub careful with the 50rms rating.

March 31, 2010

Installed the BA G112-44 in the stock rear deck cut-out of a 94 Lexus GS300. Once I removed the factory mounting bracket for the stock 10" sub the BA dropped perfectly in to the stock mounting position. When I received the unit I read the paperwork and noticed that the manufactures rating was 200rms! Immediately I called Sonicelectronix to be sure I got the right sub. This particular install require low wattage (factory amp). Customer Service stated to me that when used in a free-air application that they recommended 50 RMS. I have no idea how the recommendation came about but under A/B testing this sub needs every bit of 150rms watts to perform. With all this in mind the value of this sub can not be overstated! The fuses to change from 2ohm to 8ohms alone is worth the money. And in the free-air application even with 400rms watts going to it, it never bottomed out! Quite impressive for a free-air $80 sub. Highly recommended for any application.

You don't need 3000 watts to be heard miles away with Boston Acoustics!!!

May 17, 2009

I purchased 4 of these subs from Sonic electronix (they were great). 2 subs acoustically paired in same chamber of a still quite small box (4 cuft total). Running 200 RMS to each one I really sound like I have thousands of dollars in my Honda Passport! I am using a HiFonics Amp Brutus. Amazing--Boston Acoustic is up there with the audio gods as well! Sound quality is wonderful. J. House

Great power for the wattage

March 6, 2009

I recently purchased 2 12" Boston G1 subs, they are wired to a 400 watt Rockford Fosgate amp, I had really wanted to go with Alpine, but my dad instead got me Boston. I am very impressed, the sound is very crisp and clear, they cover low bass amazingly. I do not plan on getting rid of them anytime soon.
