Efficiency

The ability of a driver to convert electrical energy into sound energy without wasting too much electrical energy.

Frequency Range

The range of frequencies over which a particular driver can operate effectively without creating significant distortion.

Frequency Response

The relative loudness of sound output over the entire range of frequencies. Frequency response is usually expressed as +/- dB (decibel) or as a graph.

Ideal Driver

A speaker driver that delivers excellent performance in terms of polar response, power handling, efficiency, frequency range and reliability.
