Feel the bass with Boston Acoustics

If you are looking for a drop-in subwoofer solution, Boston Acoustic's GTuned Series Loaded Enclosures are the way to go. Available in single 10", 12" or dual 10", 12" models. These high quality MDF enclosures feature PowerVent tuning for optimum efficiency, impact and extension. Loaded with G1 car subwoofers that incorporate features like RadialVent cooling for increased power handling and SureSet impedance selection and protection. SureSet uses fuse protection to prevent damage from overdrive. For convenience the fuse protection has been moved from the subwoofer to the terminal cip for easier access. These loaded enclosures feature a GTuned port which uses an oversized port to reduce port turbulence giving you crisper, deeper and clearer bass.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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
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
Total RMS Power Handling
This is the total RMS power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.

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 giving your subwoofer(s) 75% - 90% of the recommended RMS rating.
200 watts
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.
400 watts
Total Peak Power Handling
This is the Total Peak Power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.

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.
400 watts
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.
Not Specified
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.
Not Specified
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).
34 Hz
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.
Not Specified
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.

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Vented / Ported
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
1
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Hatchback Style, Angled Back
Height
The height of the item, measured from top to bottom, in inches.
13-/18"
Width
The width of the item from left to right (side-to-side) measured in inches.
27-1/4"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
12-1/8"
Second Depth
The second depth is used only when the box is slanted or angled. This value is the top measurement and it is measured in inches.
15-1/8"
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
1
Terminal Type
Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Spring posts
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Two Tone Color
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

Great sub for the money i got on sale for $89.99 currently have it on a 300w Rockford Fosgate punch amp sounds amazing for so little power. If you're looking for a good sub but don't have a lot to spend i would recommend this one given the proper environment it'll hit pretty hard.

Great Sub

September 24, 2012

This sub is great. I bought it to replace my Lanzar 1000 watt sub. At first I was very pessimistic thinking that 400 watts would not do anything compared to 1000 watts. I could not have been more wrong! This sub hits at least 3x harder than my 1000 watt. It is an amazing sub for such a low price.

July 23, 2012

I put it in my 2002 Dodge Neon and hooked it up a Cerwin Vega 150 watt rms amp( HED 300.2) with line converter for the factory head unit. Its a little underpowered but it sounds awesome. This sub can reach very low frequenecies quite nicely if you dont want boomy mid bass. I have my amp's low pass set to 50 hz and its perfect. The enclosure is very large so you might consider the 10 inch version if concerned about trunk space. The sub itself is high quality, strong material with good excursion range. At 150- 200 watts you can hear it outside of the car but you wont be shaking the whole block, just so you know. Good sub, good price, respected brand-name, sounds great, nuff said.

Great Bass

July 5, 2012

This deal was too good to pass up. I have owned Boston Acoustic products for nearly 20 years and prefer their sound to most other brands in their price range i.e. Polk and Infinity. This speaker hits hard with only 150 RMS from a small Kenwood amp. The only feature I wish it had is a way to seal the port because I prefer sealed boxes, but it plays loud and clean. The fuse located on the speaker terminal cup is a nice touch, but I hope to never need to replace it. BTW it arrived with an improper label on the speaker terminals but customer service was great at helping me figure out the discrepancy.
