Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
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.
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.
220 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
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).
38 - 200 Hz

Subwoofer Enclosure

Home Subwoofer Enclosure Type
This is the type of enclosure that the home subwoofer has. Different enclosures will vary in the sounds that they produce.

Bass Reflex: These enclosures are tuned top play louder than other types of enclosures. While the sound might not be as accurate, they are able to get louder when compared to other subwoofers with a similar amplifier.

Acoustic Suspension: These enclosures will produce an accurate bass. In comparison to a another type of subwoofer with a similar amplifier, a acoustic suspension subwoofer will not be as loud. However, the bass will be much more accurate and correct.

Bass Reflex
Powered Subwoofer
This means that the home subwoofer is powered with a built-in amplifier. If it is not powered, than a separate amplifier is required.
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Paintable Frame
This means that the frame or cabinet of the speaker can be painted to match its surroundings.
In-Wall Installation
These items are designed for installation in the walls of your home.
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

amazing buy!!!

December 8, 2011

So I had been looking for a home theater subwoofer for a long time. i dont have 400 dollars to spend on a sub, so i wasnt getting anywhere. Then i saw this sub here on sale for $75 and thought "thats exactly what im looking for". So i bought it, and seeing that no one has written a review i didnt know what to expect. Well, i hooked up the sub and was blown away by the quality. THIS SUB IS GREAT!!!! It's soooo loud, i dont even have it half way turned up and it rattles my walls, and the sound doesnt knock or distort in any way. It was built very well too. Its very sturdy and the knobs and connectors are very good quality. im very impressed with this sub and would recommend it to all of my friends.
