Engineered for Clarity and Precision

The Lii Audio ST-5 is a high-performance 5-inch full-range speaker driver built for audiophiles who appreciate crisp detail, accurate imaging, and a modern, open sound signature. Featuring an aluminum cone, the ST-5 offers increased stiffness and reduced breakup, delivering clean transients and precise mid-to-high frequency response in a compact format.

With 91 dB sensitivity and a wide frequency range extending from 55 Hz to 20 kHz, the ST-5 is ideal for nearfield listening, desktop HiFi, or compact full-range enclosures. The driver’s ceramic Y35 magnet, precision-wound 25 mm voice coil, and robust motor structure ensure articulate dynamics and solid bass performance—without the need for a crossover.
