Alpine SWR-10D2 Specification

The Alpine SWR-10D2 is a high-performance subwoofer designed to deliver powerful and precise bass for car audio systems. It features a 10-inch dual voice coil configuration, allowing for flexible wiring options and compatibility with a variety of amplifier setups. The subwoofer has a power handling capacity of 1000 watts RMS and a peak power of 3000 watts, providing robust sound performance suitable for enthusiasts seeking deep, rich bass.

The SWR-10D2 is built with a Kevlar reinforced pulp cone, which is both lightweight and rigid, ensuring accurate sound reproduction and durability. Its HAMR (High Amplitude Multi-Roll) surround allows for greater cone movement and excursion without compromising sound quality, enhancing its ability to produce low-frequency sounds. The subwoofer also incorporates a cast aluminum frame with a radial vented design, contributing to efficient heat dissipation and prolonged performance reliability.

The frequency response of the SWR-10D2 ranges from 26 Hz to 200 Hz, making it capable of handling a wide spectrum of bass tones. Its sensitivity is rated at 82 dB, which, combined with its power handling capabilities, ensures that the subwoofer can deliver deep bass at high volumes without distortion. Additionally, the dual 2-ohm voice coils provide installation flexibility, allowing for series or parallel wiring to achieve the desired impedance load.

Overall, the Alpine SWR-10D2 is engineered to offer exceptional sound quality and durability, making it an ideal choice for users looking to upgrade their car audio systems with a subwoofer that delivers powerful, clean, and precise bass.

Alpine SWR-10D2 F.A.Q.

What is the optimal enclosure size for the Alpine SWR-10D2 subwoofer?

The recommended sealed enclosure volume for the Alpine SWR-10D2 is 0.65 cubic feet, while the ported enclosure should be 1.0 cubic feet for optimal performance.

How do I wire the Alpine SWR-10D2 for a 4-ohm load?

To wire the Alpine SWR-10D2 for a 4-ohm load, connect the voice coils in series by connecting the positive terminal of one coil to the negative terminal of the other. Then, connect the remaining positive and negative terminals to your amplifier.

What amplifier power rating is recommended for the Alpine SWR-10D2?

The Alpine SWR-10D2 is rated for 1000 watts RMS, so it is recommended to use an amplifier that can deliver between 750 to 1000 watts RMS at the desired impedance for optimal performance.

How can I troubleshoot if my Alpine SWR-10D2 is not producing sound?

First, check the wiring connections to ensure they are secure. Verify that the amplifier is receiving power and that its gain settings are correct. Additionally, inspect the subwoofer for any visible damage.

Can the Alpine SWR-10D2 be used in a free-air setup?

The Alpine SWR-10D2 is not designed for free-air applications. It requires a properly sized sealed or ported enclosure to perform optimally.

What is the frequency response of the Alpine SWR-10D2?

The frequency response of the Alpine SWR-10D2 is 26 Hz to 200 Hz, allowing it to handle a wide range of bass frequencies effectively.

How do I maintain my Alpine SWR-10D2 to ensure its longevity?

Regularly inspect the subwoofer for any physical damage, ensure the enclosure is sealed properly, and avoid overpowering the subwoofer. Clean the subwoofer and surrounding areas to prevent dust buildup.

What are the mounting dimensions for the Alpine SWR-10D2?

The mounting depth for the Alpine SWR-10D2 is 6.375 inches, and the cutout diameter is 9.125 inches, ensuring it fits appropriately in most standard enclosures.

How do I break in my new Alpine SWR-10D2 subwoofer?

To break in your Alpine SWR-10D2, play music at moderate volume levels for the first 10-15 hours of use. This allows the subwoofer's suspension system to loosen up and perform optimally.

What should I do if my Alpine SWR-10D2 is distorting at high volumes?

If distortion occurs at high volumes, check the gain settings on your amplifier, ensure the enclosure is sealed properly, and verify that the subwoofer is not being overpowered. Adjust settings accordingly to minimize distortion.
