SLS-85S25CP04-04

Overview

The Peerless by Tymphany SLS-85S25CP04-04 is a 3.5-inch mini-woofer featuring a coated paper cone and rubber surround. It operates with a nominal impedance of 4 ohms and handles 30 watts RMS power. The driver exhibits a resonant frequency (Fs) of 73 Hz and a frequency response range from 73 Hz to 2.5 kHz. It utilizes a ferrite magnet motor assembly equipped with an aluminum shorting ring to reduce distortion. The unit is designed for high excursion applications within compact acoustic enclosures.

Feature Summary

• Coated paper cone with rubber surround for natural bass response
• Ferrite magnet motor with aluminum shorting ring for reduced distortion
• Rigid steel basket construction for structural stability
• High excursion capability suitable for small speaker designs

Applications

• TV soundbars
• Pedestal soundbars
• Compact speaker systems requiring powerful bass in limited space

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with intended acoustic designs. Confirm that the 4-ohm impedance and 30-watt RMS rating align with amplifier specifications. Review mechanical dimensions and mounting requirements prior to integration into final products.

Selection Notes

This component is selected for its low resonant frequency and high excursion, making it ideal for mini-woofers where deep bass is required in small volumes. The combination of a paper cone and rubber surround offers a balanced tonal quality. Ensure the enclosure design accommodates the specific Thiele/Small parameters for optimal performance.

Part Context

The SLS-85S25CP04-04 belongs to the Peerless SLS series, which focuses on high-performance mini-woofers. This model specifically targets the consumer audio market, particularly integrated sound solutions. It represents a balance between cost-effective materials like paper cones and robust magnetic structures using ferrite magnets.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. When evaluating alternatives, match the 3.5-inch diameter, 4-ohm impedance, and similar Fs values. Verify that replacement drivers maintain comparable excursion capabilities and mounting hole patterns to ensure physical compatibility.
