4454

Overview

The Visaton 4454 is a 7 cm (2.5 inch) flush-mounted full-range speaker designed for integration into plastic housings with a threaded mounting ring. It features an 8 Ohm impedance and a 10 W power rating, delivering a sound pressure level of 88 dBA. The unit operates within a frequency response range of 400 Hz to 5 kHz, with a self-resonant frequency of 550 Hz. Physical dimensions include a diameter of 76 mm and a depth of 34.5 mm. It utilizes wire leads for termination and carries an IP4X protection rating, suitable for indoor applications.

Feature Summary

• Flush-mount design with integrated threaded mounting ring for secure installation in plastic enclosures
• Compact 7 cm round format optimized for space-constrained audio systems
• Wire lead termination simplifies electrical connection without solder lugs

Applications

• Integration into compact plastic housing units
• Small-scale audio reproduction systems
• Indoor public address installations requiring low profile speakers

Procurement Notes

Verify the specific impedance variant, as datasheets indicate an 8 Ohm configuration for part number 4454, while aliases may reference other values. Confirm that the wire lead termination meets the system's wiring requirements. Ensure the IP4X rating aligns with the environmental exposure limits of the intended installation site. Cross-reference the 10 W power handling against the amplifier output capabilities to prevent thermal overload during peak operation.

Selection Notes

Select this component when a small form factor is required for flush installation within plastic structures. The 8 Ohm impedance dictates amplifier matching; ensure the source can drive this load efficiently. Consider the limited low-frequency extension below 400 Hz, which necessitates complementary drivers or crossover networks if full-range coverage is essential. The wire lead interface requires compatible connector planning during the mechanical design phase.

Part Context

This model belongs to the Visaton speaker transducer portfolio, categorized under audio devices. It serves as a specialized solution for embedded audio applications where standard basket mounts are impractical. The design prioritizes ease of assembly into molded plastic components, distinguishing it from panel-mount or ceiling-mount alternatives in the manufacturer's lineup.

Replacement Considerations
