When you need to seriously pump up your lows, choose MaxxBass®, the bass enhancement technology used on more hit records and major motion pictures than any other. MaxxBass® uses psycho-acoustics to calculate precise harmonics that are related to the fundamental tones of sound. When these harmonics are combined, it creates the effect of lower, deeper frequencies. For bass you can really feel, it’s got to be MaxxBass®. Extends perceived bass response by up to 1.5 octaves, preserves the dynamic range and character off the original bass, and mixed output, maxxbass, and original bass monitoring.
