The new Perdue Acoustics' Variable Acoustics invention maximizes every aspect of acoustics - transforming performance venues from spatulated reflection, to diffusion, to maximizing its absorption abilities in every way. The result is manufactured units that can transform rooms from long reverb times without apparent echo, to rooms so tight that the loudest, punchiest performances come across crystal clear. The world's first rolling reverberation chamber is an experience like no other in acoustics, and proves, not only the value of Variable Acoustics, but the value of acoustics itself.
