ABOUT TONSIL Tonsil has kept a low profile outside of Poland under it's own name, but like many companies it's output relies heavily on OEM (Original Equipment Manufacture) contracts. Clients we manufacture for include Pioneer, Motorola, Fiat, Daewoo, and several other well known brands. Acoustical perfection is designed, built and tested in Tonsil's research and development Hi-Tech laboratories, which includes the largest anechoic chamber in Europe. The test equipment is a blend of traditional instruments, scopes, signal generators and Bruel & Kjaer mics, alongside computer-driven technology including MLSSA and LEAP software.
