Our goal was to achieve a transparent sound with no distracting peaks or troughs. One thing this requires is clear separation of lows and mids. To ensure accuracy across this critical frequency band, weve employed what is known as an acoustic back volume. Its a small chamber within a chamber we have tuned to manage the slope and amplitude of the base lift. The way the back volume helps achieve such a clear and natural sound signature is by controlling the direction and overall volume of air as it moves through the transducer system. What you hear is a pleasantly disciplined bass and mid-range experience. Unpleasant resonances and listening fatigue vanish in this small space with a big effect.An acoustic back-volume establishes balance
