The Ozren Bilan Akustika Prostorija Exclusive is a custom-designed system that takes into account the specific needs of each room. The treatment consists of a combination of absorption, diffusion, and reflection panels, carefully crafted to address specific frequency ranges and room modes. The system is tailored to the room's dimensions, shape, and construction materials, ensuring a precise and effective acoustic calibration.

The measurements demonstrate a substantial improvement in the room's acoustic characteristics, with a reduction in reverberation time and a more even frequency response.
