Choosing the perfect model of wireless speaker systems is difficult whilst faced with a large number of various terms and specifications, for example “sound pressure level”, “output power” etc. I am going to explain the specification “speaker output power” a bit more in this commentary. If you are looking to get a pair of speakers in order to install in your house, you will often be faced with a series of strange terms describing its performance. Many smaller home speakers merely can be driven with several watts power which usually is adequate for a small room. If you intend to shake your walls then you clearly want to opt for a speaker that has up to several hundred watts. “Peak power” describes how much wattage the loudspeaker may endure for a short burst. Music and voice signals naturally always vary regarding their power, i.e. The main reason is that audio signals will show brief peaks of large power which the speaker has to endure. Rms power is measured with a constant sine signal which barely compares with a music signal regarding the power envelope.
Typically the impedance of the loudspeakers that you connect to your audio amplifier will determine how much power your amplifier can provide. On the other hand, ideally the maker of your amp is going to tell which speaker impedance the amplifier can drive.
