With ordinary loudspeakers, a single amplifier can power the woofer, mid-range and tweeter through an audio crossover, which filters the signal into high- medium- and low-frequencies (or high- and low-frequencies in 2-way speakers) – a mechanism that protects each driver from signals outside its frequency range. However, the passive crossover ...
Similarly, in a constant-voltage speaker system, the amplifier uses a transformer to step up the voltage of the audio signal to reduce power loss over the speaker cable, allowing more power to be transmitted over a given wire diameter. Each speaker in the system has a step-down transformer to reduce the voltage to a usable level.
An active full-range loudspeaker. Powered speakers, also known as self-powered speakers and active speakers, are loudspeakers that have built-in amplifiers.Powered speakers are used in a range of settings, including in sound reinforcement systems (used at live music concerts), both for the main speakers facing the audience and the monitor speakers facing the performers; by DJs performing at ...
There is a switch behind the Sound Blaster X7 to switch modes between driving a pair of 4-ohms or 8-ohms passive speakers. [ 3 ] With its bundled 24V, 2.91A power adapter, it can deliver up to 27 watts per channel to 8-ohms passive speakers and up to 38 watts per channel to 4-ohms passive speakers.

Tone control is a type of equalization used to make specific pitches or frequencies in an audio signal softer or louder. It allows a listener to adjust the tone of the sound produced by an audio system to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment.
