W 170 S - 4 OHM

Overview

The Visaton W 170 S - 4 OHM is a 6.5-inch HiFi woofer featuring a coated paper cone and elastic rubber surround. It operates with a nominal impedance of 4 Ohms and a rated power handling of 50 W, with a maximum power capacity of 80 W. The frequency response extends from 36 Hz to 8 kHz, supported by a self-resonant frequency of 36 Hz. Efficiency is rated at 86 dBA (1W/1m). Key mechanical features include 4.25 mm Xmax and a ±10 mm excursion limit, designed for use as a small subwoofer or in various speaker systems.

Feature Summary

• Coated paper cone construction for balanced audio reproduction
• Elastic rubber surround ensuring extended linear excursion
• Powerful drive unit with extended rear pole plate
• Designed for integration into diverse speaker system architectures

Applications

• HiFi woofer assemblies
• Small subwoofer configurations
• General-purpose speaker system design

Procurement Notes

Verify the specific impedance variant matches the required circuit design, as the model designation explicitly indicates 4 Ohms. Confirm that the rated power of 50 W aligns with the amplifier output capabilities to prevent thermal damage. Ensure the physical dimensions accommodate the intended enclosure volume and mounting constraints. Cross-reference the frequency range specifications with the target application's acoustic requirements.

Selection Notes

Select this component when a balanced mid-bass performance is required with high excursion capability. The 4 Ohm impedance suits standard amplifier outputs. Consider the 86 dBA efficiency for sensitivity requirements. The treated paper cone offers a specific tonal character suitable for HiFi applications. Verify compatibility with the desired crossover network frequencies given the 36 Hz to 8 kHz range.
