K 28.40 H - 8 OHM

Speakers Overview

The Visaton K 28.40 H - 8 OHM is a miniature electromagnetic speaker driver featuring a neodymium magnet and paper cone within a rectangular plastic basket. It operates with an impedance of 8 ohms and a power rating of 2 watts. The frequency response spans from 390 Hz to 20 kHz, delivering a sound pressure level of 79 dB. Physical dimensions are 2.8 cm x 4.0 cm (1.1" x 1.6") with a depth of approximately 1.6 inches.

Speakers Feature Summary

• Compact design utilizing a neodymium magnet for reduced size
• Linear frequency response achieved through optimized component interaction
• Rectangular frame construction suitable for tight spaces

Speakers Applications

• Small-format audio applications requiring wide frequency range
• Miniature speaker modules for portable devices
• General purpose speakers in compact enclosures

Speakers Procurement Notes

Verify the specific suffix 'H' against official Visaton documentation to confirm magnetic shielding or housing variations. Ensure the 8-ohm impedance matches system requirements. Confirm mechanical mounting hole patterns align with enclosure designs before procurement.

Speakers Selection Notes

Select this model for applications demanding minimal footprint due to its small physical dimensions. The 2-watt power handling limits usage to low-volume or auxiliary audio roles. Consider the rectangular shape for space-constrained layouts where circular drivers do not fit efficiently.

Speakers Part Context

This component belongs to Visaton's line of miniature loudspeakers designed for integration into small electronic devices. The use of neodymium allows for high performance in a reduced volume compared to ferrite-based alternatives.

Speakers Replacement Considerations

Direct substitutes must match the 8-ohm impedance, 2-watt rating, and rectangular form factor. Verify that replacement drivers maintain similar frequency response characteristics and mounting dimensions to ensure compatibility with existing assemblies.
