Lii Song / Lii Audio F-15

15” Full-Range Driver for a Natural, Direct and Emotionally Engaging Sound

The Lii Song F-15 is a 15-inch full-range loudspeaker driver designed for music lovers who seek an open, fast and physically present sound. Sold as a matched pair, it belongs to Lii Song’s F Series, a range created for high-sensitivity loudspeaker projects, special cabinet designs and open-baffle configurations.

Its philosophy is beautifully simple: one large driver covering the full musical range, without complex crossover networks that can reduce immediacy, coherence or naturalness. The result is a direct and highly musical listening experience, with impressive scale, expressive midrange and surprisingly solid bass performance for a full-range design.

The F-15 is especially attractive for enthusiasts using tube amplifiers, low-power amplification and systems where musical emotion matters more than technical complication. With a declared sensitivity of 97.2 dB, it can deliver a vivid and dynamic sound even with modest amplifier power, making it a very interesting partner for triode, single-ended and classic low-wattage designs.

Sound Character

The F-15 offers a large, open and physically engaging presentation. Music appears with body, scale and a sense of immediacy that recalls classic high-efficiency loudspeaker systems. Voices have presence, instruments breathe naturally, and the sound never feels forced.

Thanks to its large cone surface, the F-15 provides a convincing sense of size and musical weight, especially with jazz, vocal music, blues, classical recordings and acoustic instruments. This is not a driver designed merely to impress with microscopic detail; it aims for something more important: to make music feel alive, present and emotionally real in the room.

Lyric Audio Comment

The Lii Song F-15 is not a conventional loudspeaker driver. It is a product for listeners who understand the value of well-executed simplicity: a large radiating surface, high sensitivity, no complex crossover, and a way of reproducing music that feels more direct, more physical and more emotional.

In a carefully designed system, especially with tube amplification, it can offer a very special experience: a big, natural and immediate sound, with that sense of presence that many smaller, more complex modern loudspeakers do not always achieve.
