BC25SC15-04

Overview

The BC25SC15-04 is a 1-inch (25 mm) high-frequency driver manufactured by Peerless by Tymphany. It features a treated soft dome diaphragm and a neodymium magnet assembly for high output in a compact size. The unit has a nominal impedance of 4 Ohms and a rated power handling of 100 Watts. Its frequency response spans from 1.4 kHz to 20 kHz, with a resonant frequency (Fs) of approximately 1400 Hz. Sensitivity is rated at 93 dB (1W/1m), and it utilizes a polymer faceplate with recessed waveguide loading.

Feature Summary

• Treated soft dome diaphragm for smooth, extended high-frequency response
• Neodymium magnet assembly providing high output efficiency
• Polymer faceplate with recessed waveguide loading design
• Compact 1-inch form factor suitable for space-constrained applications

Applications

• High-fidelity music audio systems

Procurement Notes

Verify the specific datasheet version before integration, as component specifications may be subject to change without notice. Confirm that the 4-Ohm impedance aligns with your amplifier or crossover network requirements. Ensure mechanical mounting dimensions match your enclosure design. Check for RoHS compliance status if required for your region. Contact the manufacturer or authorized distributors for current availability and lead times.

Selection Notes

Select this model when a compact tweeter with high sensitivity and robust power handling is required. The neodymium magnet allows for a smaller magnetic structure compared to ferrite alternatives. The recessed waveguide design aids in dispersion control. Consider the 100W rating for high-power applications. Verify compatibility with existing crossover components designed for 4-Ohm loads.

Part Context

This driver belongs to the BC series of dome tweeters from Peerless by Tymphany. The series is known for combining advanced acoustic materials with efficient magnetic structures. These drivers are engineered for demanding audio applications requiring clarity and reliability.
