Tang Band's versatile W4-2142 full range driver uses an underhung voice coil, which places the entire coil inside the magnetic gap, for the utmost in control and accuracy. Designed for minimum distortion and resonance, the bamboo fiber paper cone and structured surround produces smooth response without harsh peaks or dips. The aluminum phase plug improves off axis response while also acting as a shorting ring providing greater control of the voice coil resulting in lower distortion.
