SDS-P830656

Overview

The SDS-P830656 is a 6.5-inch (165mm) full-range loudspeaker driver manufactured by Peerless by Tymphany. It features a paper cone with a rubber surround and a steel frame construction. The unit operates with a nominal impedance of 8 ohms and has a recommended frequency range extending from 45 Hz to 20,000 Hz. Key electrical specifications include a resonance frequency (Fs) of approximately 42 Hz, an equivalent volume (Vas) of 37 liters, and a total Q factor (Qts) of 0.49. The sensitivity is rated at 87 dB, with a maximum SPL of 104 dB.

Feature Summary

• Full-range design utilizing a paper cone for balanced acoustic reproduction across the audible spectrum.
• Robust steel frame construction providing structural stability and thermal management for the voice coil.
• Rubber surround integration designed to enhance low-frequency excursion capabilities and durability.

Applications

• Home audio speaker systems requiring full-range drivers
• DIY loudspeaker enclosure projects
• Mid-bass applications in multi-way speaker configurations

Procurement Notes

Verify the specific manufacturing batch and revision status against official Peerless by Tymphany documentation prior to procurement. Ensure that the physical dimensions and mounting hole patterns match the intended enclosure design specifications. Confirm impedance ratings align with amplifier output requirements for optimal performance and safety.

Selection Notes

Select this component when a single-driver solution or a dedicated mid-bass element is required for enclosures with sufficient internal volume. Consider the Vas and Qts values to determine appropriate box tuning frequencies. Evaluate the mechanical limits regarding Xmax to ensure the driver can handle the expected power levels without distortion.

Part Context

This model belongs to the Peerless SD series of full-range drivers, known for combining efficient magnetic structures with lightweight cone materials. The series targets audiophile and professional audio markets seeking high-fidelity reproduction. The P830656 variant specifically addresses applications requiring a balance between bass extension and midrange clarity within a standard 6.5-inch form factor.

Replacement Considerations

Direct replacements must match the 6.5-inch diameter, 8-ohm impedance, and similar Thiele-Small parameters. Verify mounting depth and baffle cutout dimensions to ensure physical compatibility. Consult official substitution lists from Peerless by Tymphany for updated models with improved material compositions.

FAQ

What is the recommended enclosure type for this driver?

Due to its Qts of 0.49 and Vas of 37 liters, it is suitable for both sealed and vented enclosures, provided the internal volume is calculated to maintain optimal bass response.

Is the cone material susceptible to moisture damage?

The paper cone may be treated with protective coatings depending on the production batch; however, prolonged exposure to high humidity should be avoided to preserve acoustic integrity.
