SLS-85S25CP04-08

Overview

The SLS-85S25CP04-08 is a woofer manufactured by Peerless by Tymphany. It features an impedance of 8.45 Ohms and a rated power handling of unspecified watts in the provided data, though similar models indicate high power capacity. The frequency range extends from 74 Hz to 2.5 kHz, with a self-resonant frequency (Fs) of 73.74 Hz. Efficiency is rated at 83.30 dBA. The driver utilizes a coated paper cone and a ferrite magnet motor equipped with an aluminum shorting ring. It is housed in a rigid steel basket and employs terminal connections suitable for standard wiring.

Feature Summary

• Coated paper cone construction for balanced audio reproduction
• Ferrite magnet motor system integrated with an aluminum shorting ring to reduce distortion
• Rigid steel basket providing structural stability
• Designed for powerful bass response in compact speaker enclosures

Applications

• Consumer audio systems requiring compact bass drivers
• Small speaker designs needing powerful low-frequency output
• High-fidelity audio equipment integration

Procurement Notes

Verify the specific datasheet for complete Thiele/Small parameters as some values may vary by revision. Confirm availability status directly with authorized distributors, as product lifecycles change. Ensure the enclosure design matches the driver's mechanical dimensions and suspension requirements for optimal performance.

Selection Notes

Select this model when a compact woofer with a coated paper cone and ferrite magnet is required. The aluminum shorting ring makes it suitable for applications demanding reduced harmonic distortion. Consider the 8.45 Ohm impedance for amplifier matching and the 74 Hz lower frequency limit for enclosure tuning.

Part Context

This component belongs to the SLS family of drivers from Peerless by Tymphany. The series is characterized by components designed for consumer audio applications, offering a balance of performance and size. The SLS line typically includes various sizes to fit different acoustic requirements within small form factors.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. When replacing, ensure the new driver matches the 8.45 Ohm impedance, 74 Hz - 2.5 kHz frequency range, and physical mounting dimensions of the original unit.
