Infinity subwoofers have always distinguished themselves clearly from the competition. The Infinity SSI Kappa series subwoofers are no exception and fight on a playing field all their own. Right away the coated glass-fiber cone shows off an air of sophistication and style while offering incredible rigidity that minimizes distortion.

Once you get past the cultured exterior, the interior components uphold Infinities affinity for advanced technology. This Kappa sub utilizes a triple voice coil system which gives it the incredible ability to offer selectable impedance. Selectable Smart Impedance (SSI) technology allows this sub to run at 2 Ohms or 4 Ohms with the flick of a switch. This allows you to extract the most from your subwoofer amplifier in any situation. If you decide to add a subwoofer down the line, SSI makes it easy to reconfigure your entire system without buying different subwoofers or amplifiers.

The SSI Kappa subwoofers handle a remarkable amount of power and sound incredible in sealed or ported enclosures. If you want great sounding bass with unheard of wiring versatility, Infinity Kappa subs are technologically advanced enough to handle it.


The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

    Subwoofer Specifications

    Subwoofer Series
    Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
    Kappa (Infinity)
    Subwoofer Size
    Refers to the diameter of the subwoofer, measured in inches.
    12"
    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.
    1400 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.
    350 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.
    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.
    2 or 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).
    23 - 400 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".
    91 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.
    17.50 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.
    Gold
    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.
    Coated Glass Fiber
    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.
    Rubber
    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.
    1.00 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.
    1.00 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.
    2.00 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.
    2.00 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.
    6-5/16"
    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.
