Overview
The Visaton 4503 is an electro-dynamical exciter loudspeaker designed for audio reproduction applications. It features a rectangular body construction with dimensions of 46mm x 46mm x 15mm and weighs 63 grams. The component operates at a nominal impedance of 4 ohms and has a power handling capacity of 10 watts. Its frequency response range extends from 25 Hz to 70 kHz, allowing for broad audio coverage. This unit is classified as a discontinued or no longer available product within the manufacturer's current lineup.
Feature Summary
- Electro-dynamical exciter design for direct sound transmission
- Rectangular frame geometry suitable for panel mounting
- Wide frequency response capability up to ultrasonic ranges
Applications
- Hi-Fi loudspeaker driver integration
- High-end audio system construction
- Panel-mounted acoustic transducer systems
Procurement Notes
Verify availability status carefully as this model is listed as no longer available. Confirm exact physical dimensions and electrical specifications against current project requirements before ordering. Check for discontinued part status with authorized distributors. Ensure compatibility with existing amplifier outputs given the 4-ohm impedance rating.
Selection Notes
Consider the specific rectangular form factor when designing enclosure or panel layouts. Evaluate the 10W power rating against expected signal levels. Assess the wide frequency range suitability for intended audio content. Verify mechanical mounting constraints due to the compact 46x46mm footprint.
Part Context
This component belongs to Visaton's line of electro-dynamical exciters, which are specialized transducers designed to convert electrical signals into mechanical vibrations for direct panel excitation. Visaton specializes in German-engineered audio solutions for Hi-Fi, public address, and industrial applications. The 4503 represents a specific rectangular variant within their broader speaker driver portfolio.
Replacement Considerations
No confirmed substitute part numbers are publicly documented for this specific discontinued model. Users may need to evaluate other Visaton rectangular exciters or similar 4-ohm 10W units from alternative manufacturers based on dimensional and electrical compatibility.
