NE123W-04

Speakers Overview

The Peerless by Tymphany NE123W-04 is a 4-inch (100 mm) full-range woofer featuring a cast aluminum frame and a high-strength compact neodymium magnet system. It has an impedance of 4.15 Ohms, a frequency range of 60 Hz to 8 kHz, and a self-resonant frequency of 156.35 Hz. The driver utilizes a paper cone with a voice coil diameter of 1.28 inches and a gap height of 4 mm. Its sensitivity is rated at 85 dB, with a maximum power handling of 70 W and an Xmax of 4.3 mm.

Speakers Feature Summary

• Cast aluminum frame promotes motor cooling
• Sculpted design improves airflow and reduces reflections
• High-strength compact neodymium magnet system

Speakers Applications

• Full-range audio reproduction in compact enclosures
• DIY loudspeaker construction
• Mid-bass applications in multi-driver systems

Speakers Procurement Notes

Verify the specific datasheet revision when ordering, as parameters such as Fs and Vas may vary between documentation versions. Confirm impedance and power ratings against your amplifier capabilities. Ensure enclosure designs account for the specific Thiele/Small parameters provided in the official manufacturer documentation for this exact part number.

Speakers Selection Notes

Select this component for applications requiring a compact full-range driver with neodymium magnet efficiency. The cast aluminum frame offers thermal advantages over standard steel or plastic frames. Consider the 4-inch form factor for space-constrained installations where broad frequency coverage from a single driver is prioritized over extended low-frequency extension.

Speakers Part Context

This model belongs to the Peerless Platinum series, characterized by the use of neodymium magnets and cast aluminum frames. The series focuses on high-efficiency transducers suitable for audiophile-grade DIY projects. The NE123W-04 specifically targets the 4-inch segment, offering a balance between size and acoustic output.

Speakers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching Thiele/Small parameters precisely, particularly Fs, Vas, and Qts, which may differ significantly between manufacturers even for similar physical dimensions.
