The VIBE Space Series 12-Inch Subwoofer, model SPACE12D2-V4, is engineered for high-fidelity low-frequency sound reproduction. This manual provides essential information for the proper installation, operation, and maintenance of your subwoofer to ensure optimal performance and longevity.
The Space Series subwoofers incorporate advanced technologies such as Mechanical Thermal Unity, designed to enhance cooling and overall performance. This innovative design ensures efficient heat dissipation from the voice coil through the alloy cone, maintaining stable operation even under demanding conditions.
2. Key Features
The VIBE Space Series subwoofer is built with precision and advanced materials to deliver superior audio performance. Key features include:
- Mechanical Thermal Unity: A cutting-edge technology developed by VIBE R&D, featuring a one-piece alloy cone and flanged alloy voice coil former that work in unity for enhanced voice coil cooling.
- Reversible Front Gasket: Made from high-quality machined aluminum, the front gasket offers a high-end aesthetic and is fully reversible, allowing for rear-mounted subwoofer installations.
- Advanced Surround Design: Features a specially developed foam rubber multi-roll surround, providing improved linearity throughout the subwoofer's excursion range.
- FEA Designed Aluminum Cone: The Finite Element Analysis (FEA) designed aluminum cone ensures unmatched weight and dynamics, seamlessly joined to the flanged alloy voice coil for perfect unity and efficient cooling.
- Single Spider Control: A single spider provides precise control and stability for the woofer cone, ensuring 100% linear movement.
- Alloy Torsion Basket: Machined from cast aluminum, the torsion basket offers high rigidity and robust support for the motor and moving components of the subwoofer.

4. Setup and Installation
Proper installation is crucial for the performance and safety of your VIBE Space Series subwoofer. It is recommended that installation be performed by a qualified professional. Always disconnect the vehicle's battery before beginning any electrical work.
4.1 Enclosure Requirements
The VIBE Space Series subwoofer is designed to perform optimally in a properly sized and constructed enclosure. Consult a car audio specialist or VIBE's official resources for recommended enclosure volumes and port tuning frequencies for sealed or ported designs. An incorrect enclosure can severely limit performance and potentially damage the subwoofer.
4.2 Wiring Connections
The SPACE12D2-V4 features a dual 2-ohm voice coil configuration. This allows for flexible wiring options to achieve different impedance loads at your amplifier. Common wiring configurations include:
- 1 Ohm Load: Wire both 2-ohm voice coils in parallel. This configuration requires an amplifier stable at 1 ohm.
- 4 Ohm Load: Wire both 2-ohm voice coils in series. This configuration is suitable for amplifiers stable at 4 ohms.
Ensure all connections are secure and properly insulated to prevent short circuits. Use appropriate gauge wiring for power, ground, and speaker connections to minimize power loss and ensure safety.
4.3 Mounting
The subwoofer can be mounted in a standard front-mount configuration or a rear-mount configuration using its reversible gasket. Ensure the mounting surface is rigid and free from obstructions. Use all provided mounting screws and tighten them securely but do not overtighten.
5. Operation and Optimization
Once installed, proper tuning of your audio system is essential for optimal subwoofer performance and longevity.
5.1 Amplifier Gain Setting
Set the amplifier gain correctly to match the output voltage of your head unit. An improperly set gain can lead to clipping, which can damage the subwoofer. Start with the gain at its minimum, play a test tone or music, and slowly increase the gain until distortion is audible, then back off slightly.
5.2 Crossover Settings
Utilize the low-pass filter (LPF) on your amplifier or head unit to ensure the subwoofer only reproduces low frequencies. A typical LPF setting for subwoofers is between 60 Hz and 100 Hz, depending on your main speakers and personal preference. Avoid sending full-range signals to the subwoofer.
5.3 Break-in Period
Allow a break-in period of approximately 20-30 hours of normal listening before pushing the subwoofer to its maximum capabilities. This allows the suspension components (surround and spider) to loosen up and reach their optimal compliance.
6. Maintenance
The VIBE Space Series subwoofer requires minimal maintenance to ensure its long-term performance.
- Cleaning: Use a soft, dry cloth to gently wipe down the cone and surround. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect the subwoofer for any signs of damage to the cone, surround, or dust cap. Check all wiring connections for tightness and corrosion.
- Environmental Factors: Protect the subwoofer from extreme temperatures, direct sunlight, and excessive moisture.
7. Troubleshooting
If you experience issues with your VIBE Space Series subwoofer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound from Subwoofer |
|
|
| Distorted Sound |
|
|
