The "Triangle-ROUNDS-F" is a high-performance corner bass trap designed to absorb low frequencies and reflect sound. Made from acoustic foam and laminated HDF, it features velvet fabric for an elegant finish. Its compact size (420x420x420 mm) allows for easy integration into various interiors without disrupting decor.
These bass traps target the low-frequency energy that accumulates in room corners, improving bass clarity and definition. They reduce standing waves, flutter echoes, and unwanted reflections, making them ideal for any acoustic setup. By minimizing natural reverberation, they enhance sound quality, particularly in the lower frequencies.
