TG9FD10-04

Overview

The Peerless by Tymphany TG9FD10-04 is a 3.5-inch (89 mm) full-range driver featuring a patented NRSC fiberglass cone and rubber surround. It has a nominal impedance of 4 ohms, with a DC resistance of 3.2 ohms and voice coil inductance of 0.07 mH. The unit utilizes a ferrite magnet motor system with a copper pole piece cap to control impedance. Rated for 10 W power handling, it delivers an efficiency of 84 dB and operates within a frequency range of 100 Hz to 20 kHz. The mechanical Q (Qms) is specified at 3.

Feature Summary

• Patented NRSC fiberglass cone construction
• Copper pole piece cap for impedance control
• Ferrite magnet motor system
• Rubber surround design

Applications

• Portable audio devices
• Compact speaker enclosures
• Cost-effective full-range systems

Procurement Notes

Verify the specific ordering suffix matches the required impedance and configuration. Confirm datasheet revisions align with current production standards. Ensure compatibility with intended enclosure designs regarding Thiele/Small parameters. Check for any regional availability restrictions or alternative part numbers from authorized distributors before finalizing procurement.

Selection Notes

Select this component when a compact full-range solution is required for portable applications. The fiberglass cone offers distinct acoustic characteristics suitable for general reproduction. Consider the 4-ohm impedance for matching with standard amplifier outputs. Evaluate the 84 dB sensitivity against enclosure volume constraints to ensure adequate output levels without excessive amplification.

Part Context

This model belongs to the TG family of full-range drivers from Peerless by Tymphany. These units are engineered for cost-effective performance in small form factors. The series typically employs polymer chassis and specialized cone materials to balance weight and rigidity. This specific variant focuses on delivering extended high-frequency response within a limited physical footprint.

Replacement Considerations

Direct substitutes may include other 3.5-inch full-range drivers with similar 4-ohm impedance and mounting dimensions. Verify Thiele/Small parameter compatibility to maintain original tuning. Alternative models might offer different cone materials or magnet types while fitting the same application space.
