Overview
Premium Subwoofer for Superior Performance
Durability and Longevity
The Image Dynamics ID12 V.4 Subwoofer is constructed with a durable rubber surround that ensures longevity and resistance to wear. Its Poly/Mica cone combines strength and lightweight properties for a balance between durability and accurate sound reproduction. The subwoofer also features a Nomex spider, which enhances the suspension system for better sound control and long-term reliability. These components make it highly durable, capable of performing in demanding environments.
Precision Sound Engineering
This subwoofer is equipped with a polycarbonate neck joint that strengthens the connection between components, ensuring precise audio output even under high loads. The extended Y-35 motor structure provides greater power handling and improved magnetic efficiency, resulting in cleaner and more accurate bass. Its universal enclosure application makes it versatile for use in both sealed and ported boxes. This flexibility allows users to customize their setup for the best possible sound experience.
Product Highlights
Product Specifications
| General Specifications | |
|---|---|
Continuous Power Handling (RMS) Continuous Power Handling (RMS) refers to the amount of power a subwoofer can handle continuously, measured in watts. This ensures the subwoofer operates efficiently without distortion or damage during extended use, providing reliable performance.
|
|
Peak Power Handling Peak Power Handling is the maximum power a subwoofer can handle in short bursts, measured in watts, without damage. It represents the highest power level the subwoofer can manage for brief moments, unlike continuous RMS power.
|
|
Recommended Amplifier Power (RMS) Recommended Amplifier Power refers to the optimal power range, measured in watts, that a subwoofer should receive from an amplifier. This ensures the subwoofer performs efficiently without risking damage or distortion during use.
|
|
Frequency Response Frequency Response refers to the range of frequencies a subwoofer can reproduce, typically measured in Hertz (Hz). It shows the lowest and highest tones the subwoofer can effectively deliver, with wider ranges providing more detailed sound reproduction.
|
|
Voice Coil Size Voice Coil Size refers to the diameter of the voice coil in a subwoofer, typically measured in inches. It impacts the subwoofer’s power handling and performance, with larger voice coils generally allowing for more power and better heat dissipation.
|
|
| Physical Specs | |
Overall Diameter Overall Diameter is the total outer measurement of a subwoofer, from one edge to the opposite edge, including the mounting frame. This dimension is important for ensuring the subwoofer fits correctly in the intended installation space.
|
|
Mounting Hole Diameter Mounting Hole Diameter refers to the size of the hole required to fit the subwoofer into an enclosure. This measurement ensures the subwoofer can be properly installed without gaps or fitment issues.
|
|
Bolt Hole Circle Diameter Bolt Hole Circle Diameter refers to the diameter of the circle passing through the centers of all mounting bolt holes on a subwoofer. It ensures proper alignment for securing the subwoofer to an enclosure or mounting surface.
|
|
Mounting Depth Mounting Depth refers to the distance from the mounting surface to the back of a subwoofer. It indicates how much space is needed for the subwoofer to fit properly in an enclosure or vehicle without obstructing other components.
|
|
Net Weight Net Weight refers to the total weight of a subwoofer, excluding packaging or any additional accessories. It is an important factor for installation and handling, as heavier subwoofers may require more secure mounting and can affect vehicle performance.
|
|
| Parameters | |
Free Air Resonance (Fs) Free Air Resonance (Fs) is the frequency at which a subwoofer's cone naturally vibrates without an enclosure, measured in Hertz (Hz). A lower Fs value indicates better low-frequency response, allowing the subwoofer to produce deeper bass.
|
|
Electrical “Q” (Qes) Electrical "Q" (Qes) measures the electrical damping of a subwoofer, primarily determined by the voice coil and magnet system. It influences how efficiently the subwoofer converts electrical power into motion, affecting its performance in different boxes.
|
|
Mechanical “Q” (Qms) Mechanical "Q" (Qms) measures the mechanical damping of a subwoofer, focusing on the suspension components like the surround and spider. A higher Qms indicates less mechanical resistance, affecting the subwoofer's efficiency and transient response.
|
|
Total Speaker “Q” (Qts) Total Speaker "Q" (Qts) is the overall damping factor of a subwoofer, combining mechanical (Qms) and electrical (Qes) properties. It helps determine how the subwoofer performs in different enclosure types, influencing sound quality and bass response.
|
|
Equivalent Compliance (Vas) Equivalent Compliance (Vas) represents the volume of air that has the same compliance (springiness) as the subwoofer's suspension. Measured in liters, it helps determine the ideal enclosure size for the subwoofer to achieve optimal performance.
|
|
Mms Mms refers to the total moving mass of a subwoofer, including the cone, surround, and voice coil. Measured in grams (g), it affects the subwoofer's responsiveness and bass output, with lower Mms typically providing faster and more accurate bass.
|
|
One-Way Linear Excursion (Xmax) One-Way Linear Excursion (Xmax) is the maximum distance a subwoofer’s cone can move in one direction without distortion. Measured in millimeters (mm), it indicates how much air the subwoofer can displace, affecting its ability to produce deep bass.
|
|
Efficiency Efficiency refers to how effectively a subwoofer converts electrical power into sound. It is usually measured in decibels (dB) per watt at a 1-meter distance. A higher efficiency rating means the subwoofer can produce more sound with less power.
|
|
Effective Piston Area (Sd) Effective Piston Area (Sd) is the surface area of a subwoofer cone that moves air to create sound, measured in square centimeters (cm²). A larger Sd increases air displacement, resulting in stronger bass output.
|
|
| Sealed Enclosure Specifications | |
Sealed Volume Sealed Volume refers to the internal air space within a sealed subwoofer enclosure. This volume is crucial for controlling the subwoofer’s movement and affects bass response. A properly calculated sealed volume results in tight, accurate bass.
|
|
| Ported Enclosure Specifications | |
Ported Volume This is a net volume, which does not include speaker displacement or port displacement.
|
|
Tuning Frequency Tuning Frequency is the frequency at which a subwoofer enclosure is designed to resonate, maximizing bass output. It’s typically measured in Hertz (Hz) and is crucial for balancing deep bass response and loudness, particularly in ported enclosures.
