BCD-3951-17-4-006

Overview

The BCD-3951-17-4-006 is a magnetic tweeter manufactured by Glass Acoustic Innovations Co. Ltd., currently classified as obsolete. It features a top port design with an oval or rectangular frame and operates within a frequency range of 500 Hz to 20 kHz. The unit has a nominal impedance of 4 Ohms, a power handling capacity of 30 W, and a sensitivity of 86 dB. Its self-resonant frequency is specified at 1.2 kHz.

Feature Summary

• Top port acoustic configuration
• Oval or rectangular frame geometry

Applications

• High-frequency audio reproduction in speaker systems

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is limited to existing stock or secondary market sources. Verify part authenticity and condition carefully when sourcing from distributors. No new production units are expected. Ensure compatibility with existing enclosure designs before procurement.

Selection Notes

Select this model only for legacy system maintenance or specific retrofit applications requiring its unique top-port and oval frame characteristics. Consider modern equivalents if current production support is required. Evaluate acoustic integration needs against its fixed 4 Ohm impedance and 30 W power rating.

Part Context

Glass Acoustic Innovations produces specialized acoustic components. This tweeter belongs to their magnetic driver lineup, distinguished by its specific porting and frame shape. It serves niche audio engineering requirements where these physical and electrical parameters are critical for system performance.

Replacement Considerations

No public confirmed substitute part numbers are available for this obsolete component. Engineers must evaluate generic replacements based on matching impedance, sensitivity, and frequency response curves rather than direct cross-referencing.
