[Pre-Sale] Douk Audio S4 Dual 4-Inch 2-Way Passive Bookshelf Speakers

Features Dual 4-Inch Sound with Real Body: Built for listeners who want richer, more grounded sound from a passive bookshelf speaker, each S4 uses dual 4-inch mid-bass drivers to handle lower mids and bass with more ease. Vocals gain warmer presence, drums hit with cleaner impact, and audio feels fuller and more complete without loose boom. Three Drivers for Layered Texture: A coated 25mm silk dome tweeter with a neodymium motor keeps highs smooth and clear. Nomex composite mid-bass drivers, long-excursion design, and shorting rings support steadier cone control and lower distortion. The result is richer texture and cleaner separation, making complex music easier to follow. Acoustic Tuning for Balanced Playback: A 3kHz crossover with selected MKP capacitors and air-core inductors refines the handoff between the silk tweeter and dual mid-bass drivers. The tuned bass-reflex cabinet reinforces low-end body through controlled airflow, giving S4 a more cohesive, well-balanced playback character. Bi-Wire and Bi-Amp Ready: With 4Ω impedance and 50W AES / 100W Max power handling, S4 is designed as a natural match for most Douk Audio, Nobsound, and Ampapa amplifier setups. Bi-wire and bi-amp ready terminals let advanced HiFi systems separate high and low frequency paths for cleaner signal flow, stronger drive control, and future upgrades. Piano Gloss with Modern Elegance: Made to be seen, the white piano-gloss cabinet softens the equipment-heavy look of traditional speakers. On speaker stands, shelves, desktop setups, or audio racks, it becomes a polished focal point. Rounded edges, no veneer edges to lift, protective grilles, and anti-slip foot pads keep the pair clean, stable, and display-ready.
