Design and Construction

The SP-382PA features a meticulously engineered diaphragm that balances flexibility with structural integrity, allowing it to reproduce low frequencies with minimal distortion. The driver’s enclosure is crafted from high‑density composite material, providing excellent rigidity while keeping the overall weight manageable for installation in various settings.

Its 8 Ω impedance aligns seamlessly with standard amplifier outputs, ensuring compatibility across a broad spectrum of audio equipment. The built‑in crossover network is tuned to deliver a smooth transition between midrange and bass frequencies, preserving clarity even at high output levels.

Acoustic Performance

With a sensitivity rating of 94 dB/W/m, the SP-382PA delivers powerful sound with efficient energy usage. This makes it capable of producing substantial bass impact without requiring excessive amplifier power. The driver’s frequency range extends down to 30 Hz, enabling deep sub‑bass reproduction that enriches music, movies, and live performances.

Its low distortion characteristics are evident in the clean, articulate sound across the entire audible spectrum. Whether used as a standalone unit or integrated into a multi‑speaker array, the SP-382PA maintains tonal balance and delivers consistent performance over extended listening periods.

Applications

• Professional Audio: Ideal for live sound reinforcement, concert venues, and club systems where robust bass is essential.
• Home Theater: Enhances cinematic experience by providing deep, immersive low‑frequency effects.
• Studio Monitoring: Offers accurate bass reproduction for mixing and mastering tasks.
• Custom Installations: Its compact depth of 150 mm allows integration into tight spaces such as in‑car audio systems or portable speaker designs.

Installation Considerations

The SP-382PA’s moderate weight (3.9 kg) and shallow enclosure depth facilitate straightforward mounting on walls, ceilings, or within cabinets. For optimal performance, it is recommended to position the driver in a well‑ventilated area to prevent thermal buildup during prolonged operation.

When integrating into an existing system, ensure that the amplifier’s output power matches the driver’s 150 W RMS rating to avoid over‑driving and potential damage. The 8 Ω impedance also allows for flexible wiring configurations, including series or parallel arrangements with other drivers.

Maintenance Tips

• Inspect the speaker cone regularly for signs of wear or damage; replace if necessary to maintain sound quality.
• Keep the driver’s enclosure free from dust and debris, especially in high‑traffic environments.
• Avoid exposing the unit to extreme temperatures or moisture, which can compromise internal components.

Conclusion

The SP-382PA Woofer – 103320 stands out as a versatile, high‑quality driver capable of delivering deep, clear bass across diverse audio contexts. Its thoughtful design, robust specifications, and reliable performance make it an excellent choice for anyone seeking dependable low‑frequency reproduction in both professional and personal settings.
