BG 20 - 8 OHM

Overview

The Visaton BG 20 - 8 OHM is an 8-inch (20 cm) full-range electromagnetic speaker featuring a tweeter dome. It operates within a frequency range of 38 Hz to 18 kHz with a self-resonant frequency of 38 Hz. The unit has an impedance of 8 Ohms, a sound pressure level of 92 dBA (measured at 1W/1m), and a power rating of 40 W. It utilizes panel mount installation with solder lug termination. The circular driver measures 205 mm in diameter and 82 mm in depth, designed for robust audio reproduction.

Feature Summary

• Integrates a dedicated tweeter dome into the full-range design for extended high-frequency response.
• Provides high efficiency with a 92 dBA sound pressure level output.
• Features a round shape suitable for direct panel mounting applications.

Applications

• Small vocal monitors
• Guitar monitors
• Mid-range units in multi-driver systems

Procurement Notes

Verify the specific suffix matches the required impedance and power handling before ordering. Confirm that the panel cutout dimensions align with the 205 mm diameter specification. Ensure the solder lug terminals are compatible with the intended wiring harness. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate the 40 W power rating against the amplifier output capabilities.

Selection Notes

Select this component when a single-driver solution is required for mid-to-high frequency coverage without complex crossovers. The high efficiency reduces the demand on amplification power. Consider the physical depth of 82 mm for enclosure constraints. The 8 Ohm impedance is standard for many consumer audio circuits. Evaluate the 38 Hz low-frequency limit to ensure it meets bass requirements.

Part Context

This model belongs to the Visaton full-range speaker series, which combines midrange and treble reproduction in a single transducer. The inclusion of a tweeter dome distinguishes it from basic cone speakers, allowing for clearer high-frequency articulation. It is engineered for compact audio systems where space and simplicity are prioritized over wide-bandwidth fidelity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing enclosures and mounting hardware when considering alternative models from other manufacturers.
