SLS-P830946

Overview

The SLS-P830946 is a 8-inch subwoofer driver from the Peerless by Tymphany SL Series. It features a paper cone with a rubber surround and a cast aluminum frame. The motor assembly utilizes a copper shorting ring (Faraday shield) to reduce inductance modulation. Key parameters include an 8-ohm nominal impedance, a resonance frequency of 27 Hz, and a maximum linear excursion of 10 mm. The effective radiating area is 352 cm², supported by a compliance of 1.1 mm/N.

Feature Summary

• Copper shorting ring integrated into the motor structure for reduced distortion
• Rubber surround designed for high excursion capability
• Cast aluminum frame providing structural rigidity

Applications

• High-fidelity loudspeaker systems
• Home theater subwoofers
• Professional audio low-frequency reproduction

Procurement Notes

Verify the specific revision code on the datasheet or manufacturer confirmation before ordering. Ensure mechanical mounting dimensions match the enclosure design. Confirm thermal handling requirements align with the intended amplifier power output. Check for any recent updates to the terminal configuration or material specifications.

Selection Notes

Select this component when designing sealed or vented enclosures requiring deep bass extension. The 10 mm Xmax supports high SPL applications without significant non-linear distortion. Consider the 8-ohm impedance for compatibility with standard consumer amplifiers. Evaluate the Qts value for optimal enclosure volume calculations.

Part Context

This model belongs to the SL Series, which focuses on balanced performance between size and output capability. The series is engineered for both professional and high-end consumer audio markets. The use of a paper cone aims to provide a neutral tonal character while maintaining durability under high stress conditions.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Alternative drivers require recalculation of enclosure volumes and crossover networks due to differences in Thiele/Small parameters.
