Alpine SWR-8D4 Specification

The Alpine SWR-8D4 is a high-performance 8-inch subwoofer designed to deliver powerful and precise bass. It features a dual voice coil configuration with each coil rated at 4 ohms, allowing for versatile wiring options to optimize amplifier performance and system compatibility. The subwoofer is capable of handling a continuous power rating of 350 watts RMS and can manage peak power handling up to 1,000 watts, making it suitable for both moderate and high-powered audio systems.

Constructed with a Kevlar reinforced pulp cone, the SWR-8D4 ensures durability and maintains sound integrity even under demanding conditions. It is paired with a HAMR (High Amplitude Multi-Roll) Santoprene surround that enhances linearity and allows for greater excursion, contributing to its robust low-frequency response. The subwoofer's design incorporates a progressive spider with reinforced layers, which enhances stability and control during extended play.

The SWR-8D4 also features an airflow management system that facilitates efficient cooling of the motor structure, reducing thermal build-up and improving reliability over time. Featuring a mounting depth of 5-3/4 inches, it is compact enough for various installation scenarios while delivering deep and impactful bass. With a frequency response range of 30 Hz to 200 Hz, the Alpine SWR-8D4 is capable of reproducing a wide spectrum of low frequencies, making it an excellent choice for enhancing the audio experience in car sound systems. Its combination of advanced materials and innovative design ensures that it meets the demands of audiophiles seeking high-quality bass performance in a compact form factor.

Alpine SWR-8D4 F.A.Q.

How do I properly wire the Alpine SWR-8D4 subwoofer for optimal performance?

To wire the Alpine SWR-8D4 subwoofer, you can use either series or parallel wiring, depending on your amplifier's capabilities. For a 4-ohm load, wire the dual 4-ohm voice coils in series. For a 2-ohm load, wire them in parallel. Always ensure your amplifier supports the impedance you choose.

What is the recommended enclosure size for the Alpine SWR-8D4 subwoofer?

Alpine recommends a sealed enclosure with a volume of 0.35 cubic feet or a ported enclosure with a volume of 0.6 cubic feet for the SWR-8D4 subwoofer to achieve optimal sound quality.

What should I do if my Alpine SWR-8D4 is not producing sound?

First, check the wiring connections for any loose or disconnected wires. Ensure the amplifier is powered on and functioning properly. Verify that the subwoofer settings on the head unit are correct and that the gain on the amplifier is adjusted appropriately.

How do I break in my new Alpine SWR-8D4 subwoofer?

To break in your Alpine SWR-8D4, play music with moderate bass at a moderate volume for the first 20-30 hours of use. This helps the suspension components settle and improves overall performance.

Can the Alpine SWR-8D4 handle continuous high power output?

The Alpine SWR-8D4 is designed to handle a continuous power output of 350 watts RMS. Ensure your amplifier's power output matches this rating to prevent damage to the subwoofer.

What is the frequency response range of the Alpine SWR-8D4?

The Alpine SWR-8D4 subwoofer has a frequency response range of 30 Hz to 200 Hz, allowing it to effectively reproduce low bass frequencies.

How do I troubleshoot an Alpine SWR-8D4 with distorted sound?

Check if the subwoofer is overloaded by reducing the volume and bass levels. Ensure that the amplifier gain is set correctly and that all connections are secure. Also, inspect the subwoofer cone and surround for any physical damage.

What maintenance is required for the Alpine SWR-8D4?

Regularly check the wiring connections and the condition of the enclosure. Keep the subwoofer clean and free from dust. Avoid exposing it to extreme temperatures and moisture to prolong its lifespan.

How do I adjust the settings for the best sound quality on my Alpine SWR-8D4?

Adjust the amplifier's crossover settings to a low-pass filter of around 80 Hz. Set the gain properly to match the input level from the head unit. Experiment with the positioning of the subwoofer within the vehicle for optimal bass response.

What are the installation considerations for the Alpine SWR-8D4?

Ensure adequate space for the enclosure and ventilation to prevent overheating. Use quality speaker wires and connectors for reliable performance. Follow the manufacturer's guidelines for proper installation to avoid damaging the subwoofer.
