BF 32 S - 4 OHM

Overview

The Visaton BF 32 S - 4 OHM is a compact full-range speaker transducer designed for audio applications. It features a nominal impedance of 4 Ohms and a power rating of 10 W. The unit operates within a frequency range extending from 150 Hz to 18,000 Hz. Key acoustic specifications include a sound pressure level of 86 dBA and a resonance frequency (Fs) of 150 Hz. The physical dimensions are approximately 32 mm in diameter with a depth of 14 mm, utilizing solder lug terminals for connection.

Feature Summary

• Compact full-range driver design suitable for space-constrained audio enclosures
• Balanced frequency response optimized for midrange clarity
• Robust construction with standard solder lug termination for easy integration

Applications

• DIY loudspeaker kits and open baffle designs
• Small portable audio devices
• Replacement drivers for vintage or custom audio equipment

Procurement Notes

Verify the specific suffix against official Visaton documentation to confirm impedance and power ratings. Ensure compatibility with existing enclosure volumes and crossover networks. Check for RoHS compliance status if required by project specifications. Confirm terminal type matches assembly requirements.

Selection Notes

Select this component when a small form factor is critical alongside adequate midrange performance. Consider the 4 Ohm impedance for matching with compatible amplifiers. Evaluate the 10 W power handling against peak signal levels. Compare Fs and Qts values with simulation tools to predict enclosure behavior accurately.

Part Context

This model belongs to the Visaton BF series, which focuses on high-quality full-range drivers for audiophile and professional audio markets. The BF 32 variant specifically targets applications requiring minimal footprint without sacrificing tonal balance. It complements larger woofers in multi-driver systems or stands alone in dipole configurations.

Replacement Considerations

Direct substitutes may include other Visaton models with similar diameter and impedance, such as the BF 25 S or BF 40 S, depending on spatial constraints. Verify mechanical mounting hole patterns and magnetic structure dimensions before substitution.
