W4-1337SDF 4" Titanium Full Range Speaker

The Tang Band W4-1337SDF is a remarkable 4-inch titanium full-range speaker that redefines what a compact driver can achieve. Designed to deliver clear, detailed sound across the entire audible spectrum, this broadband driver eliminates the need for a separate tweeter in many applications, making it an ideal choice for high-fidelity audio projects where space is at a premium.

This versatile speaker excels in a variety of settings, from near-field desktop monitors and portable Bluetooth speakers to custom soundbars and small-scale home theatre systems. Its full-range capability also makes it perfect for DIY audio enthusiasts building minimalist, high-quality loudspeakers or upgrading existing multi-way designs where a dedicated midrange driver is required.

Technically, the W4-1337SDF features a titanium diaphragm that ensures precise transient response and low distortion, while the ferrite magnet motor system provides efficient power handling. With a sensitivity of 89 dB (SPL 1m/2.83V) and a total Q factor (Qts) of 0.34, it offers a balanced blend of efficiency and controlled bass response. The 2.5 mm linear excursion (Xmax) and low voice coil inductance (Le: 0.03 mH) contribute to its ability to reproduce subtle details with accuracy. The 4-inch nominal diameter (101.6 mm) and 82.3 mm depth allow for flexible enclosure design, while the 95 mm cut-out diameter and four mounting holes simplify installation.

In summary, the Tang Band W4-1337SDF delivers exceptional full-range performance from a compact, well-engineered driver, making it a superb choice for discerning audio builders.
