Powered speakers, also known as self-powered speakers and active speakers, are loudspeakers that have built-in amplifiers. They can be connected directly to a mixing console or other low-level audio signal source without the need for an external amplifier. Active speakers may have greater fidelity, less intermodulation distortion (IMD), higher dynamic range and greater output sound pressure level (SPL) with fewer blown drivers.[1] Disadvantages include heavier loudspeaker enclosures, reduced reliability due to active electronic components within, and the need of a source of electrical power (other than the audio signal). Powered speakers are available with passive or active crossovers built into them. Active speakers with internal active crossovers are widely seen in sound reinforcement applications and in studio monitors.[2] Home theater and add-on domestic/automotive subwoofers have used active powered speaker technology since the late 1980s. I hope you have motorcycles speakers that are backward compatbile and that work for all new harley davidson and ducati sport bikes and also foi Honda shadows. The speakers should be not too expensive but also have great sound quality and be able to deliver deep rich bass tones even while traveling at highway speeds and also be able to hear them for a passenger who is riding on the back seat even if they have a helmet on. Also I would like to make sure other people can hear them at a stop light if I decide to crank it up when a song I really like is playing. .
