FR 10 HM - 4 OHM

Speakers Overview

The Visaton FR 10 HM is a 10 cm (4-inch) full-range loudspeaker driver designed for high-fidelity audio reproduction. It features a nominal impedance of 4 ohms and a power handling capacity of 25 watts RMS, with a maximum input power of 60 watts. The frequency response spans from 80 Hz to 20,000 Hz, providing balanced midrange and treble performance. Key electrical parameters include a resonance frequency (Fs) of approximately 75 Hz and an efficiency (SPL) of 86 dB at 1W/1m. The unit utilizes a neodymium magnet system for compact size and strong magnetic flux.

Speakers Feature Summary

• Integrated neodymium magnet structure for enhanced magnetic field strength within a reduced volume.
• Full-range design eliminating the need for crossover networks in simple two-way or single-driver configurations.
• Robust suspension system optimized for linear excursion and low distortion in the mid-frequency range.

Speakers Applications

• Compact bookshelf speaker enclosures requiring integrated mid-bass and treble output.
• DIY audio projects focusing on minimalist two-way or three-way speaker designs.
• Replacement drivers for vintage or modern compact hi-fi systems.

Speakers Procurement Notes

Verify the specific suffix code on the datasheet to confirm impedance and terminal type before ordering. Ensure the enclosure volume matches the Thiele-Small parameter recommendations for optimal bass response. Check for any regional variations in mounting dimensions or voice coil wire material if sourcing from different distributors.

Speakers Selection Notes

Select this driver when space constraints limit the use of larger woofers but full-range coverage is desired. Consider the 4-ohm impedance for compatibility with standard amplifier outputs. Evaluate the Thiele-Small parameters against the intended cabinet volume to ensure proper tuning and avoid excessive cone excursion at low frequencies.

Speakers Part Context

This model belongs to Visaton's FR series of full-range drivers, known for their versatility in small enclosures. The 'HM' designation typically refers to specific magnet materials or construction techniques used by Visaton to optimize performance-to-size ratios. It serves as a core component for enthusiasts building efficient, compact audio systems without complex multi-driver crossovers.

Speakers Replacement Considerations

Direct replacements are limited due to unique Thiele-Small parameters. When substituting, match the diameter, mounting hole pattern, and depth. Compare Fs, Qts, and Vas values closely to maintain similar acoustic behavior in the existing enclosure design. Consult Visaton technical support for cross-reference availability.
