XT25SC30-04

Overview

The XT25SC30-04 is a 1-inch dual ring radiator tweeter from Peerless by Tymphany. It features a silk diaphragm and a neodymium motor for low distortion. The design includes a rear chamber to extend low-frequency response. Key specifications include a 4-ohm impedance, 91.9 dB sensitivity, and a frequency response range of 400 Hz to 20,000 Hz. The resonant frequency (Fs) is 440 Hz.

Feature Summary

• Patented dual concentric ring radiator diaphragm
• Waveguide center plug for improved dispersion
• Silk diaphragm material
• Rear chamber for extended bass response

Applications

• High-resolution audio systems
• Professional loudspeaker drivers
• Hi-Fi home theater speakers

Procurement Notes

Verify the specific suffix 'SC' against official Tymphany documentation to confirm magnet type and exact electrical parameters, as datasheets may vary by revision. Ensure compatibility with crossover networks designed for 4-ohm loads. Confirm physical mounting dimensions match enclosure designs before purchase.

Selection Notes

Select this model for applications requiring wide dispersion and high sensitivity. The neodymium motor offers a compact form factor compared to ferrite alternatives. Consider the rear chamber requirement when designing speaker enclosures to utilize the extended low-frequency capability effectively.

Part Context

This component belongs to the XT series of ring radiator tweeters by Peerless by Tymphany. The series utilizes patented dual-concentric diaphragm technology. The XT25SC30-04 variant specifically denotes the 4-ohm impedance version with a silk dome construction.

Replacement Considerations

Direct substitutes include the XT25TG30-04 (ferrite magnet) or XT25SC90-04 (neodymium magnet, different response). Verify impedance and sensitivity differences when swapping between these variants to maintain system balance.
