Topperfo units are made of wood. They absorb the full range of frequencies
from low to high. Nothing is better than uniformly high-quality acoustics. The
quality of a concert performance can never be better than the quality of the covering of the ceiling and walls. Even in your own home music can sometimes sound like noise.
Topperfo panels are available for walls, ceilings and cabinet fronts in a wide range of different perforations, including conventional M-perforation, discreet T-perforation and micro-perforation (Clou).
