Active speakers have a custom built-in amplifier (typically a PC speakers). Conversely, passive systems require an external amplifier, from which the sound goes to each speaker.

It is defined as the amount of energy per unit of time and is expressed in watts.

In terms of frequency range, speakers are produced with different properties. It is due to both, its purpose and secondly, the physical properties of individual structures. It is the lowest value in...

The number of bands refers to the number of frequency bands that the loudspeaker or system reproduces. A single-band loudspeaker produces all the sounds from a single transducer, while a multi-band loudspeaker has multiple transducers, each optimised for a specific frequency range (e.g. high, mid, low frequencies). Multiband systems often provide better sound quality because each band can be reproduced by a transducer designed specifically for that frequency range.
