Insulator
A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity.

Brooks QS 70 Diffraction
The breaking up of a sound wave caused by some type of mechanical interference such as a cabinet edge, grill frame, or other similar object.

Fader

Bottom
The bass frequencies (as in "needs more bottom end").

High-Pass Filter
A device that rejects signals that are below a certain frequency (called the cut-off frequency) and passes signals with frequencies that are higher.
