AccuEQ

AccuEQ calibration technology reveals the true potential of your speakers by eliminating standing waves from your listening space. These acoustic peaks distort the audio image and prevent your loudspeakers from voicing the sound as their designers intended. AccuEQ lets you experience the whole sonic picture without changing your speaker system’s unique personality.
