Tang Band W4-655F Full-range Driver

The Tang Band W4-655F features a 4" paper cone and rubber surround combination, delivering smooth midrange response and rich tonal character. With a sensitivity of 89 dB (1W/1m) and a frequency response ranging from 70 Hz to 14 kHz, it performs exceptionally in compact full-range enclosures or as a midbass unit in multi-driver systems. Its golden phase plug is not just visually distinct but also optimizes dispersion, reducing phase cancellations in the upper frequencies. A 25 mm CCAW voice coil on a Kapton bobbin, mounted in a magnetically shielded motor, ensures thermal stability and low distortion. The unit handles up to 50 watts peak and is well-suited for nearfield listening and audiophile-grade builds. Whether you're designing a desktop monitor or custom bookshelf speaker, the W4-655F is a solid sonic foundation.
