BC25SC08-04

Overview

The Peerless by Tymphany BC25SC08-04 is a dome tweeter featuring a neodymium motor and ferrofluid-filled gap. It utilizes a damped fabric diaphragm for smooth frequency response. The unit has a nominal impedance of 4 ohms with a measured impedance of 3.27 Ohms. Frequency range spans from 2.5 kHz to 20 kHz, with a self-resonant frequency of approximately 1663 Hz. Sensitivity is rated at 94.90 dBA efficiency, reaching up to 99.3 dB SPL at 1m/2.83V. The voice coil handles up to 100 watts of power.

Feature Summary

• Neodymium magnet motor structure
• Ferrofluid filled motor gap
• Damped fabric diaphragm
• Enhanced voice coil cooling

Applications

• High-fidelity speaker systems
• Professional audio equipment
• Home theater installations

Procurement Notes

Verify the specific suffix -04 indicates the 4-ohm impedance variant when ordering. Confirm the presence of the integrated waveguide if required for your acoustic design, as this model includes it. Ensure compatibility with your crossover network given the 4-ohm nominal impedance and high sensitivity ratings. Check physical mounting dimensions against your enclosure design specifications before finalizing procurement.

Selection Notes

Select this component when high efficiency and smooth treble response are prioritized in compact enclosures. The neodymium motor provides strong magnetic control relative to size. Consider the 4-ohm impedance for standard amplifier matching. The fabric dome offers a natural sound signature suitable for critical listening applications where distortion must be minimized across the upper frequency spectrum.

Part Context

This tweeter belongs to the BC family of drivers by Peerless by Tymphany. The series is characterized by the use of neodymium motors and ferrofluid cooling to enhance power handling and thermal stability. The BC25SC08-04 specifically denotes the 4-ohm version within this lineup, sharing core construction elements like the 25 mm voice coil and fabric dome with other impedance variants.

Replacement Considerations

The BC25SC08-08 serves as a direct substitute offering identical acoustic performance but with an 8-ohm impedance rating. Verify that the target amplifier or crossover network can accommodate the impedance difference without affecting damping factor or frequency response characteristics.
