SDS-P830855

Overview

The SDS-P830855 is a 4-inch bass-midwoofer from the SDS series by Peerless by Tymphany. It features an 8-ohm nominal impedance and a 30-watt power rating. The driver utilizes a coated paper cone with a rubber surround, suspended in a ferrite magnet motor. Key electrical parameters include a sensitivity of 83.1 dB at 1 meter/2.83 volts and a resonant frequency (Fs) of 66 Hz. The unit employs a truncated cosmetic steel frame and includes maximum motor venting for thermal management.

Feature Summary

• Coated paper cone construction paired with a durable rubber surround
• Ferrite magnet motor system with high-power voice coil suspension
• Truncated cosmetic steel frame design
• Maximum motor venting for enhanced thermal dissipation

Applications

• Woofer in small format two-way speaker systems
• Midrange driver in three-way speaker configurations
• Compact subwoofer applications

Procurement Notes

Verify the specific datasheet version before procurement to ensure compliance with current manufacturing standards. Confirm that the 8-ohm impedance and 30-watt rating align with your amplifier output capabilities. Check RoHS compliance status if required for your region. Ensure mounting dimensions match your enclosure design specifications prior to ordering.

Selection Notes

Select this component when a compact 4-inch driver is required for mid-bass reproduction. The 66 Hz resonant frequency suits applications needing extended low-frequency response in small enclosures. The coated paper cone offers a balance of rigidity and damping suitable for general audio reproduction. Consider the 8-ohm impedance for compatibility with standard consumer audio amplifiers.

Part Context

This model belongs to the SDS series, which focuses on cost-effective drivers for compact audio solutions. The series typically combines treated paper cones with rubber surrounds for durability. Peerless by Tymphany designs these units for integration into portable or space-constrained speaker systems where size constraints limit larger driver options.
