GBS-115N25AL01-04

Speakers Overview

The Peerless by Tymphany GBS-115N25AL01-04 is a 4.5-inch (114 mm) aluminum dome woofer designed for shallow enclosure applications. It features a nominal impedance of 4 ohms and a power rating of 20 W. The driver exhibits a frequency response range of 50 Hz to 4.5 kHz with a self-resonant frequency of approximately 80.82 Hz to 90 Hz. Sensitivity is rated between 81.80 dB and 84.2 dB at 1W/1m. The unit utilizes an anodized aluminum dome and NdFeB magnet, offering large excursion capabilities within a low-profile form factor.

Speakers Feature Summary

• Anodized aluminum dome construction for extended high-frequency response
• Low-profile design enabling installation in shallow enclosures
• High linear excursion capability for powerful bass reproduction

Speakers Applications

• Shallow-mount subwoofer systems
• Compact audio enclosures requiring deep bass extension
• Custom automotive or home theater installations with space constraints

Speakers Procurement Notes

Verify the specific datasheet version for the GBS-115N25AL01-04 to confirm exact Thiele-Small parameters, as values may vary slightly between production batches. Ensure compatibility with existing amplifier output impedance. Confirm mounting depth requirements against enclosure specifications before finalizing procurement.

Speakers Selection Notes

Select this model when space is limited but significant bass output is required. The aluminum dome offers distinct tonal characteristics compared to paper or composite cones. Consider the 4-ohm impedance for matching with standard amplifier outputs. Evaluate the shallow mounting depth against available cabinet volume to optimize performance.

Speakers Part Context

This component belongs to the Peerless GBS series, which specializes in full-range and woofer drivers utilizing aluminum dome technology. The series is engineered to balance acoustic performance with physical constraints, targeting applications where traditional deep-magnet designs cannot fit. The GBS-115N25AL01-04 specifically targets the 4.5-inch segment.

Speakers Replacement Considerations

Direct replacements are limited due to specific Thiele-Small parameter dependencies. Alternative models from the same GBS series with similar diameter and impedance should be evaluated for dimensional compatibility. Verify that substitute drivers maintain comparable sensitivity and excursion limits to preserve system tuning.
