FR 8 - 4 OHM

Speakers Overview

The Visaton FR 8-4 OHM is a full-range loudspeaker driver with a nominal impedance of 4 ohms. It features an 80 mm (3.15 inch) cone diameter and a square frame design. The unit has a rated power handling capacity of 10 watts and operates within a frequency range extending from 120 Hz to 20 kHz. The speaker utilizes a coated paper cone for the diaphragm material. It weighs approximately 130 grams and complies with RoHS standards.

Speakers Feature Summary

• Square frame construction designed for compact mounting applications
• Coated paper cone diaphragm for balanced audio reproduction
• Full-range capability covering mid-bass to high frequencies

Speakers Applications

• DIY loudspeaker enclosure projects
• Small portable audio devices
• Replacement drivers in vintage audio equipment

Speakers Procurement Notes

Verify the specific suffix or variant against official Visaton documentation to ensure compatibility with the intended circuit design. Confirm that the 4-ohm impedance matches the amplifier output requirements. Check for any updated mechanical dimensions in the latest datasheet before finalizing enclosure designs.

Speakers Selection Notes

Select this model when a compact, square-profile driver is required for small enclosures. Ensure the application does not demand deep bass extension below 120 Hz, as this is a full-range unit. Verify that the 10-watt power rating aligns with the expected signal levels to prevent thermal damage.

Speakers Part Context

This component belongs to the Visaton FR series of full-range drivers. It is engineered for general-purpose audio reproduction where space constraints limit the use of larger circular drivers. The square frame allows for tighter packing in multi-driver arrays or smaller boxes compared to round equivalents.

Speakers Replacement Considerations

Direct substitutes must match the 4-ohm impedance, 80 mm effective diameter, and square frame geometry. Verify that replacement units maintain similar resonance frequency and total Q factors to preserve the original acoustic characteristics.
