Hybrid Cone

Egyptian Papyrus-Blend Cone [+]

The NVX X-Series features an ultra stiff, lightweight cone material custom made from finely milled pulp & Egyptian Papyrus fibers. The cone is treated with a soft matte black finish for a stylish and modern look.

Vertically Attached oSD Surround

Patented Surround Technology [+]

XQW woofers are engineered with a unique oSD (oversized SD) surround. This patented technology involves attaching the surround on a vertical edge for increased surface area, which translates to more bass. Additionally, the surround itself is constructed with a multi-radius elliptical edge for incredibly symmetrical, linear cone movement.

Aluminum Shorting Ring

Aluminum Shorting Ring [+]

Another feature which seperates the X-Series from other woofers on the market is the innovative aluminum shorting ring. The shorting ring is basically a conductive aluminum ring placed between the pole piece and the voice coil former. The purpose of this ring is essentially to reduce the negative effects of the inductance that is inherently present in any loudspeaker. In short, this shorting ring will:

  • Improves power delivery to the voice coil
  • Decreases distortion
  • Contributes to linear cone movement
  • Improves high-end extension
  • Decreases risk of overheating
Optimized for Small Enclosures

Space Efficient Design [+]

These subwoofers only require 6" of mounting depth to produce intensely powerful bass. NVX utilized the latest loudspeaker technology to design a space-saving subwoofer without the anemic sound of typical shallow-mount woofers. NVX claims that the X-Series is "The discerning listener's alternative" to such shallow subwoofers, and we agree.

High Temperature Voice Coil

3" High Temperature Voice Coil [+]

The stout 3" high temperature voice coil is constructed from a copper wire wrapped around an aluminum former. This industry standard design is powerful enough to readily drive the cone with strict linear control, yet at the same time remains efficient enough for the compact, space saving magnet structure.

Low Turbulence Basket

Custom Cast Aluminum Basket [+]

The custom basket of the X-Series woofer is striking in terms of both aesthetics and engineering. A particularly open basket was designed in order to improve airflow for superior cone response and reduced back-wave interference. NVX engineers chose aluminum both for its exceptional strength-to-weight ratio, as well as to eliminate interference with the magnet structure.

High-Excursion Tinsel Leads

High Excursion Tinsel Leads [+]

The tinsel leads used in the X-Series woofer are a small example of the incredible attention to detail of the NVX engineers. These tinsel leads are attached at the basin of each fold in the spider with sufficient slack for full excursion. This prevents damage to the leads from the movement of the cone, while also keeping them securely attached to prevent mechanical noise.

    Subwoofer Specifications

    Subwoofer Series
    Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
    X-Series (NVX)
    Subwoofer Size
    Refers to the diameter of the subwoofer, measured in inches.
    10"
    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.
    500 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
    Voice Coil Diameter
    Diameter of voice coil, usually measured in inches.
    3"
    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 - 200 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".
    87 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.
    20 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
    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
    Magnet Structure
    Defines the overall structure of the subwoofers magnet.
    Double Stacked
    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.
    0.25 cubic feet
    Optimum Sealed Box Volume
    This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
    0.57 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.
    0.50 cubic feet
    Optimum Ported Box Volume
    This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
    0.74 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.
    4-7/8"
    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.
    9-13/16"

    Electromechanical Parameters

    Free-Air Resonance (Fs)
    The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
    33 Hz
    Equivalent Compliance (Vas)
    This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
    25 liters
    Total Speaker Q Value (Qts)
    This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
    0.35
    Electrical Q Value (Qes)
    The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.
    0.38
    Electrical Resistance of Voice Coil (Re)
    Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
    5.8 ohms
