The Qlang M4s acoustic systems feature thin enclosures made of solid wood, with a depth of only 12 cm. Inside, a dense matrix structure is used, designed to reduce the resonances of the enclosure walls. The acoustic design follows a closed configuration with a passive bass radiator. Each speaker is equipped with an 18‑cm SEAS mid/bass driver with a paper cone and a special coating, and a Morel tweeter with a silk dome from the manufacturer’s high‑end series.
