Right front view of the Sony SRS XB40 speaker.
The SRS XB40 Sony Bluetooth speaker is a small to medium power, tabletop style unit with enough output power to fill a typical household size room with big sounding tunes.
But what does the amount of power output a wireless speaker has, tell us about how good it is? Firstly, the watt is a measure of how much power the speaker consumes or outputs. Plus, this metric is a convenient comparison measure. E.g. Generally speaking, speakers with more output audio power tend to play louder than those with less. And while they do cost more, have bigger, heavier batteries and chargers, along with larger drivers and magnets, they nonetheless offer greater dynamic range, have a deeper bass response, and the models that do stereo offer typically a bigger soundstage and better imaging to listeners.
Thus in general, the more powerful the speaker, the better it sounds, even at lower volume. You get improved clarity due to higher accuracy reproduction of the bass, midrange, and treble musical content. More reserve power could mean less clipping distortion too. So, the speaker’s maximum power output is a primary indicator of speaker quality and performance. And as such, this value is of great interest to audiophiles and novice listeners alike.
In this case, the Sony XB40, as a smaller wireless Bluetooth speaker, is a decently loud model for all the bigger it is. Its music power output can fill a room with crystal clear music. See below for details on its power output.
