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.  \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"STYLE2\"\u003e \u003c\/p\u003e\n\u003cul class=\"STYLE2\"\u003e\n\u003cli\u003eAcoustic 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.  \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"STYLE2\"\u003e \u003c\/p\u003e\n\u003cul class=\"STYLE2\"\u003e\n\u003cli\u003eBi-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.
