    Subwoofer Specifications

    Subwoofer Size
    Refers to the diameter of the subwoofer, measured in inches.
    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.
    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.
    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
    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.
    600 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.
    300 watts
    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.
    Nitrile Butadiene Rubber (NBR)
    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.
    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.
    0.45 cubic feet
    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".
    82 dB
    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.
    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.

    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.
    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.

    Why did you choose this?
    Sonic Electronix Store
    i have a jeep and wanted a sub that would fit in the back seat of it.also why i ordered a marine grade one is because if it rained with the top off it would be fine.
    Jeffrey T B on Apr 25, 2015
    I see some of the Subs spec indicate non amplified. explain please and which would you recommend for a boat?
    A shopper on May 26, 2015
    Best Answer: Hello,

    You are going to want to consult your installer and/or do a bit more research to establish an answer to your question. Amplified vs Non-Amplified literally means one is amplifier (i.e. there's an internal amplifier Powering the subwoofer) and the other is NOT (i.e. you will need to purchase an external amplifier). Which is "better" or "recommended" is established by YOU and YOUR project. Please give our sales team a call for details, as there are far too many variables to give you an elaborate answer at this time.
