SLS-P830945

Overview

The Peerless by Tymphany SLS-P830945 is a 5.25-inch paper cone woofer designed for compact subwoofer applications. It features a rigid steel basket, a wide rubber half-roll surround, and a ferrite magnet motor equipped with an aluminum shorting ring to improve distortion performance. The driver has a nominal impedance of 4 ohms, a power handling rating of 50 watts, and a frequency response range of 20 Hz to 20 kHz. Key electrical parameters include a DC resistance of 2.71 Ohms (±5.0%) and a total Q factor derived from its low Fs design.

Feature Summary

• Paper cone construction paired with a wide rubber half-roll surround for high excursion capability
• Ferrite magnet motor system integrated with an aluminum shorting ring to reduce distortion
• Rigid steel basket structure providing mechanical stability for compact enclosure mounting

Applications

• Extremely compact subwoofer enclosures
• High-excursion bass reproduction systems
• Compact audio speaker designs requiring low Fs characteristics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required impedance and power ratings. Confirm that the aluminum shorting ring specification matches the intended acoustic performance goals. Check for any recent updates to the SLS series documentation regarding mechanical dimensions or thermal limits before finalizing procurement orders.

Selection Notes

Select this component when designing small-volume subwoofers that require high excursion and low resonant frequency. The 4-ohm impedance and 50-watt rating suit moderate-power applications. Ensure the enclosure design accommodates the specific Thiele/Small parameters associated with the paper cone and rubber surround combination for optimal bass extension.

Part Context

This model belongs to the Peerless SLS Series, which focuses on compact speaker solutions. The SLS-P830945 specifically targets the subwoofer segment within this family, utilizing a 5.25-inch format. It shares design philosophies with other SLS drivers but is optimized for lower-frequency reproduction through its specific motor structure and suspension materials.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. When sourcing alternatives, match the 5.25-inch diameter, 4-ohm impedance, and similar Thiele/Small parameters to maintain acoustic performance in existing designs.
