Term	Definition	Demo
Bass	Low-frequency audio signals. Frequencies below approximately 300Hz (below 100Hz in cars).
Bass Boost/Cut	An electrical filter designed to increase or decrease the amount of bass reproduced by an audio system.
Bass Control	A tone control allowing the user to boost or cut the low frequency portion of the audio signal.
Bass Management	A function in a multichannel surround processor that combines the low bass frequencies from all of the channels (including the LFE channel) in a recording, and directs it to the appropriate loudspeakers. To do this, the customer must tell it the number, kind (small or large), and placement of loudspeakers, and whether there is a subwoofer in the system. See: LFE
Bass Reflex	A low-frequency loudspeaker enclosure design in which the volume of the enclosure and the dimensions and shape of a vent, or port, form a Helmholtz resonance which is designed to integrate with the performance parameters of a woofer. Such systems are characterized by increased acoustical output at certain frequencies near the system resonance, less output at lower frequencies, and the potential for reduced distortion at high sound levels.
