The amp features a 12dB/octave sub-sonic filter, adjustable from 10 to 50 Hz. Ultra-low frequencies that cannot be reproduced by the subwoofer do not become sound but unnecessary oscillations, which affect sound by causing distortion. These frequencies also waste amplifier power and can cause damage to the speakers. The sub-sonic filter removes the frequencies below the frequency setting to improve the performance of the speakers by eliminating harmful distortion.The MTX TD500.1D is designed with specific features to power your subwoofer or subwoofers with a frequency range between 20 to 220 Hz. This amplifier is not designed to power a full-range speaker.
