The G2 Boston Acoustics Experience

G212-44 subwoofers are great when looking for bass that won't over power you. With this subwoofer you will be able to experience a fuller sound when listening to your music at a level that is comfortable but still deep. The dual 4 ohm voice coil makes the subwoofers great for wiring a single subwoofer at 2 ohms or a pair of subwoofers at 1 ohm or 4 ohms final impedance. This makes them the perfect subwoofer for any application.

Boston Acoustics has built from their previous subwoofer to bring you their new G2 series subwoofers. These subwoofer are not only an improvement but stay true to the quality and performance that comes with Boston Acoustics products. Available in a 10", 12", and 15" 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 G2 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. G2 subs also feature 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. All G2 series subwoofers feature a co-polymer woofer cone and foam surround for rigidity and increased excursion. So if you are looking for a subwoofer that can deliver deep bass, high sensitivity and long excursion, then the G2 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.
G2 (Boston Acoustics)
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.
300 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
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".
92.3 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.
13.3 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
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
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
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.
7-3/16"
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.

Awesome subs

October 6, 2012

I installled 2 dvc's in a box I built to 2 cu ft. and I am thoroughly impressed. Unreal lows even at high power levels yet still give great mid sound as well. I've put close to 400wrms of Rockford power to each and haven't given off signs of hating life yet. Underated for sure. Would advise single coils though to get the impedance down w/o needing 1 ohm stable amp. Excellent build quality. Highly recommend these subs.

way under rated

July 28, 2012

Beats both my Tornado Kenwood 12's

August 10, 2011

This sub hits harder than both my Tornado Kenwood 12 inch subs. That's amazing and it also sounds better at a higher volumes as well as cleaner at lower frequencies. If I had two of these I think I could blow out my back window, but that would be no fun and I still want to keep my hearing. Awesome sub.

Fantastic sub that hits hard and is a great price

September 19, 2010

I had an alpine e10 and traded it out for this boston g212 and im blown away. the boston hits harder and cleaner and makes my suv rumble. im giving it 300 watts from my amp and could probably be giving it around 400 and it would hit even harder. id say its almost as loud as 2 10s. great sub. highly recommend.

boston g2-jl w3`s 12`s

May 29, 2010

This sub is just the best sub on earth. boston acoustic g2 is amazing for simple reasons really the sub can never blow. it has fuses on the sub so they pop before your voice coils do, very important important when tight on money. subs maybe need 100 watts to make this baby knock. or if u got a nice 300 rms amp don't be afraid to turn that amp up sub can handle it and will show for it. i had just the one boston g2 in a 32 ht ported box prefect i am a bass freak it was exactly what i was looking for got the sub on ebay brand new for 60$ half price from here but still wanted to comment of how great the sub really is. but like i said i am bass freak so i ended getting a sicker setup in two 12 jl w3s in a jl prowedge box with the g2 all 3 running off a rockford fosgate 300.1 tested in a db run at 148.

Great product

March 10, 2010

This is a great sub for the price. It started off slow, but after a month it bangs louder than the two MTX subs I had before. don't be afraid to push it. Looking forward to picking up a G3 at some point.

Boston Acoustic 12in G2

May 14, 2009

I have owned two bostonacoustic G2's for about six months now these speakers are amazing. They are clear and hit extremely hard. Matched with a good amp and the right size box these will give a lot of other subs a run for there money. I have mine in a sealed box right now, they are louder than some of my friends vented and ported setups. Personally i think having them vented would produce too much base. But overall these subs exceeded my expectations by far and still hit as hard as the day i got them.

WOW!

February 24, 2009

I just bought This Boston G212-44 sub in a G-tuned box and all I can say is wow! I was on a tight budget, so I paired this package with an Alpine mrp-500 monoblock and it sounds so good. The amp puts out more than enough power. This sub hits the lows very well, and will boom when you need it to. The bass is so tight and clean i can\'t get over it. I would take this subwoofer over the JL W3 any day!

great subwoofer

January 30, 2009

ok so i just installed my stinger 4 gauge amp kit and my boston acoustics g2 12 is broken in all the way and i have to say WOW!! it hits a lot lower than i thought. i am giving it about 500-600 watts i am trying not to give it the full power but there is no power level thing so i just keep the bass boost at 6 db's and it hit it really does. i have only one in a 2 cubic foot ported box tuned to 32-33 hz and it is so smooths just amazed me. if you are looking for a subwoofer that does not need that much power to get low and pretty loud for a single 12 trust me this is all you! if you want something that is going to hit 140+ db's get a memphis m3 mojo and about a 1000 watts or a Fi BL 12 and about a 1000 watts. this is primarily a SQ woofer but being that it is so efficient it can get loud it is very affordable and i promise i have bout a lot of cheap subwoofer this one is by far my best buy, boston is the way to go

Great subwoofer

January 21, 2009

I have this subwoofer in my 1996 grand am and it is hooked up to a profile 1000 watt monoblock that puts out about 600 watts and it sounds great. It's not broken in yet but I can only imagine what it will sound like. I can turn the bass down and listen to super clean bass or I can crank it up and let it bang with the best of them. This subwoofer is worth its weight in gold, to me!! I have heard several subwoofers and i could not make up my mind on what I wanted, I finally decided to go with this one cause I have heard nothing but good news about it, and it was worth it. If you get one you will not be disappointed. I can't wait to get the new boston acoustic g5 when they re-design it.

Warm Boom

August 22, 2008

Before I bought this sub i spent a month and half researching subs. I've read nothing but good things about this sub. So when i hooked mines up i had high expectations and it met them. Goes low, hits cleans, and most of all is just a warm sound coming out of it. I listen to a wide range of sound and it brings it every time. I'll say the same thing i've seen in countless other reviews. I can only wonder what the G5 sounds like. I run a single sub system and i can be heard pretty far away if thats' your thing. Im a audiophile so i'm all about listening experience and this sub has raised my standard for sound.

Top 10 Deal on this site.

April 25, 2008

I was hesitant about ordering from this site but couldnt pass up the deal on 1 of these subs. It was a toss up between this sub and an Alpine Type R. I listened to the Alpine at a local retailer, but my gut instinct was tell me to go with the The Boston. I'm glad I did. I have it in a 1 cft box pushed by an Alpine M500 and this thing is amazing. What ever U listen to this sub can keep up. The bass is so tight and well controlled, yet can go deep when needed with out sounding excessively boomy. It says it handles 300 watts rms but I have 500 watts rms running to it with the gain half way Oops! It hasn't bottommed out yet. Just let her break in for a few hours. If it blows I will just get a G5. That's another great deal by this retailer.
