Dipoles are often used as surround speakers. See also Bipole . Discrete output transistors Discrete devices are real transistors, capacitors and resistors that make up an amplifier. Discrete outputs offer higher current capacity, handle more heat, work over a wider impedance range, react faster to sonic transients, and thus in general produce lower distortion, more dynamic and lifelike sound. The degree to which a speaker's sound is spread over the listening area.
Dynamic range Refers to the difference between loud and soft sounds.
Efficiency Indicates how well a speaker system converts power into sound. This is measured by sending one watt of power and measuring the decibels at one meter distance. Flat Flat is a good thing. It is the ability of the speaker to accurately reproduce a signal without adding colorations to the sound. The human ear responds to frequencies from approximately 20 to 20,000 Hz.
