K 28 WPC BL - 8 OHM

Speakers Overview

The Visaton K 28 WPC BL - 8 OHM is a miniature general-purpose loudspeaker featuring an 8-ohm nominal impedance and a 1-watt power handling capacity. It delivers a frequency response range from 300 Hz to 20 kHz with a self-resonant frequency of 700 Hz. The unit utilizes a plastic Mylar diaphragm and includes a top round port design for sound projection. Its efficiency is rated at 75 dBA, providing balanced audio reproduction suitable for compact electronic assemblies.

Speakers Feature Summary

• Features a plastic Mylar diaphragm for balanced frequency response
• Includes mounting ears or fastening strap for secure installation
• Designed as a general-purpose full-range miniature speaker

Speakers Applications

• Compact consumer electronics audio output
• Intercom systems requiring small form factor speakers
• Portable notification devices

Speakers Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure correct impedance and terminal type. Confirm physical dimensions match the enclosure design, specifically noting the 37.6 x 28 mm footprint. Check for any specific mounting hardware requirements associated with the fastening strap or ears before finalizing procurement orders.

Speakers Selection Notes

Select this component when space constraints require a 2.8 cm diameter driver with standard 8-ohm impedance. It is appropriate for applications needing moderate efficiency (75 dBA) and voice reproduction clarity. Ensure the driving circuit can handle the 1-watt maximum power rating without distortion during peak signal levels.

Speakers Part Context

This model belongs to Visaton's line of miniature loudspeakers designed for integration into small enclosures. The K series typically offers cost-effective solutions for basic audio tasks. The specific variant uses a Mylar cone material, distinguishing it from paper or composite diaphragm options in the broader product family.

Speakers Replacement Considerations

Direct substitutes must match the 8-ohm impedance, 1-watt power rating, and similar frequency response range. Verify that alternative models accommodate the same physical mounting dimensions and terminal configuration to ensure compatibility with existing PCB layouts or wiring harnesses.
