SLS-135F32CP01-04

Overview

The Peerless by Tymphany SLS-135F32CP01-04 is a 133 mm (5.25 inch) bass-midwoofer featuring a coated paper cone and rubber surround. It utilizes a ferrite magnet motor structure with a nominal impedance of 4 Ohms and a DC resistance of approximately 2.88 to 3.14 Ohms. The driver has a power rating of 50 W and an energy bandwidth product (EBP) calculated as fs divided by Qes. Its frequency response spans from 50 Hz to 5 kHz, with a self-resonant frequency around 50 Hz, making it suitable for low-mid bass reproduction in compact enclosures.

Feature Summary

• Coated paper cone construction paired with a durable rubber surround for linear excursion
• Ferrite magnet motor system providing efficient magnetic flux for the voice coil
• Designed specifically for dedicated low-mid bass duties or compact full-range applications

Applications

• Dedicated low-mid bass driver in multi-way speaker systems
• Compact subwoofer units requiring controlled bass extension
• Small enclosure audio projects prioritizing mid-bass clarity

Procurement Notes

Verify the specific datasheet version when ordering, as impedance values may vary slightly between documentation sources (e.g., 4 Ohm nominal vs. 2.88 Ohm DC resistance). Confirm package contents and terminal types directly with the supplier. Ensure the application environment matches the driver's thermal and mechanical limits. Cross-reference the part number suffix to guarantee exact component matching.

Selection Notes

Select this model when a 5.25-inch form factor is required for low-mid frequencies. The ferrite motor offers a cost-effective solution compared to neodymium alternatives while maintaining high power handling. Consider the EBP value to determine suitability for sealed versus vented box designs. This driver is optimal for applications where paper cone warmth and rubber surround compliance are preferred over rigid composite materials.

Part Context

This unit belongs to the SLS series from Peerless by Tymphany, which focuses on robust bass-midwoofer performance. It shares design philosophies with other models like the SDS-135F25CP02-04 but distinguishes itself through its specific 50 W rating and 4 Ohm configuration. The series emphasizes reliable mid-bass output using traditional materials like paper cones and ferrite magnets.

Replacement Considerations

The SDS-135F25CP02-04 is a related model within the same family, offering similar dimensions and material construction. Verify if the slight differences in power handling and resonance parameters meet the specific acoustic requirements before substituting.
