FR 7 - 4 OHM

Speakers Overview

The Visaton FR 7 - 4 OHM is a general-purpose full-range speaker driver manufactured by Visaton GmbH & Co. KG. It features a rectangular square frame design with a nominal impedance of 4 Ohms and a rated power handling capacity of 5 Watts. The unit operates within a frequency range of 130 Hz to 20 kHz, with a self-resonant frequency of 250 Hz. It delivers an efficiency of 86 dBA when tested at 1W/1m. The physical dimensions are approximately 2.6 inches in diameter, with a shallow mounting depth suitable for compact enclosures.

Speakers Feature Summary

• Compact full-range design with shallow mounting depth
• General-purpose audio reproduction capability
• Square frame construction for versatile installation

Speakers Applications

• Compact audio enclosure integration
• DIY speaker projects requiring small form factors
• Replacement drivers for legacy equipment

Speakers Procurement Notes

Verify the specific impedance rating matches the target circuit requirements before procurement. Confirm that the mechanical dimensions fit the intended enclosure space. Check for RoHS compliance status if environmental regulations apply to the final product assembly. Ensure the power handling capacity aligns with the amplifier output specifications to prevent damage.

Speakers Selection Notes

Select this component when a small, full-range driver is required for tight spaces. Consider the 4-ohm impedance for compatibility with standard low-impedance amplifiers. Evaluate the 86 dBA efficiency against system gain requirements. The square frame may offer different mounting advantages compared to round chassis designs in specific cabinet layouts.

Speakers Part Context

This model belongs to Visaton's line of general-purpose full-range speakers. It is designed for applications where size constraints limit the use of larger drivers. The product is currently listed as active by the manufacturer, indicating ongoing production support and availability through authorized distributors.

Speakers Replacement Considerations

Direct substitutes must match the 4-ohm impedance and similar frequency response characteristics. Verify mechanical mounting hole patterns and depth compatibility. Consult manufacturer documentation for cross-reference lists or recommended equivalent models from the same product family.
