T1 can be used for medium absorption in small rooms or in large rooms where additional absorption is
necessary to provide acoustical comfort.
T3 can be used where high absorption is necessary. The panel in this form is effective for controlling
reverberation and echo formation inside rooms designed for speech related activities due to higher
absorption performance at mid-to-high frequencies.
T4 can be used where high absorption is necessary on wall surfaces and can function to provide optimum
reverberation desired for a room.
T6 can be used where high absorption is demanded for low frequency range, especially suited for
electroacoustic sound reinforcement with music material of dominant low-frequency energy content in such
