The MA series utilizes Soundbox custom inorganic microporous fiber composite acoustic cotton. This custom acoustic cotton differs from traditional insulation cotton, featuring semi-rigid fibers with elongated fibers measuring 35-40mm/5.5-6.0μm (insulation cotton typically consists of 15-20mm/7.5-8.5μm short, thick flexible and rigid fibers).

Baililong fiber boasts superior eco-friendly properties, with particle emission levels ≤0.06mg/m³ (national E1 standard value ≤0.15mg/m³) and zero formaldehyde (no detectable TVOC organic compound gases).
Custom inorganic semi-rigid, long-fiber acoustic cotton physically creates a network of interconnected micro-long holes layered with air pockets, generating powerful broadband absorption effects. Custom acoustic cotton products achieve sound absorption coefficients as high as ≥0.96 (equivalent to 1.5 times that of thermal insulation acoustic products). This high-performance solution significantly reduces material usage, thereby lowering investment costs.
MA30/50 is a horizontally mounted model featuring a unique space-blasted aluminum metallic finish and an acoustic fabric cover. Its rear incorporates a non-symmetrical baffle-absorber surface. The matrix not only efficiently absorbs direct sound from the space but also serves as an optimal absorption structure for low-frequency standing waves in ceiling cavities. This product is a highly efficient, wide-band sound capture solution designed to integrate seamlessly into diverse environments.
