SDS-P830657

Overview

The Peerless by Tymphany SDS-P830657 is a 6.5-inch bass-midwoofer from the SDS series, featuring an 8-ohm nominal impedance and a coated paper cone with a rubber surround. It utilizes a high-power voice coil suspended in a ferrite magnet motor. The driver offers a frequency response of 40 Hz to 4,000 Hz, with an RMS power handling of 60 Watts and a maximum power handling of 110 Watts. It achieves a sensitivity of 89 dB at 1 meter/2.83V and has a resonant frequency (Fs) of 48 Hz.

Feature Summary

• Coated paper cone construction paired with a durable rubber surround for consistent performance.
• Ferrite magnet motor system designed to support high-power voice coil operation.
• Smooth frequency response extending into the midrange with low distortion characteristics.

Applications

• Small surround sound systems
• Two-way speaker configurations utilizing separate tweeters
• DIY audio transducer projects

Procurement Notes

Verify the specific manufacturing date code against current inventory records, as component specifications may evolve over time. Confirm that the ferrite magnet motor and paper cone materials align with your acoustic design requirements. Ensure the 8-ohm impedance matches your amplifier output stage capabilities. Check for any recent product change notices regarding the SDS series before finalizing procurement orders.

Selection Notes

Select this model when a smooth midrange transition is required alongside a dedicated tweeter. The 6.5-inch diameter provides a balance between bass extension and cabinet size constraints. Consider the 48 Hz resonant frequency for enclosure tuning calculations. The 60-watt RMS rating suits moderate power applications. Evaluate the off-axis response consistency if wide dispersion is a priority for the listening environment.

Part Context

This component belongs to the Peerless SDS family, known for combining Danish engineering principles with cost-effective manufacturing. The series emphasizes smooth frequency response and low distortion. The SDS-P830657 specifically targets applications requiring reliable bass-midwoofer performance without premium pricing. It serves as a foundational transducer for various consumer and professional audio enclosures.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Designers should evaluate other SDS series drivers or comparable 6.5-inch woofers based on impedance and sensitivity matching. Verify mechanical dimensions and magnetic structure compatibility before substituting components in existing enclosure designs.
