The SRS XB13 Sony Bluetooth speaker is a low power, one-person style, small unit with still enough audio watts RMS to fill a small room or personal space with strikingly full sounding music or speech.
But what do the watts a Bluetooth speaker has, tell you about it? Firstly, the watt is a measure of the amount of power the speaker draws and delivers. Plus, this metric is a handy comparison measure. E.g. Typically, speakers with more watts RMS tend to play louder than those with lower max wattages. The ones with greater power cost more, have bigger batteries and chargers, along with larger drivers. But they also offer more dynamic range, have a deeper bass response, and stereo models offer a bigger soundstage to listeners.
Thus in general, the more powerful the speaker, the better it sounds, even at low volume. You get better clarity due to higher accuracy reproduction of the bass, midrange, and treble pieces of the music. More extra watts could produce less clipping distortion as well. So, the speaker’s output watts number is a primary indicator of speaker quality and performance, and as such, is of great interest to audiophiles and novice listeners alike.
In this case, the Sony XB13, as a mini battery powered BT speaker, is a reasonably well powered model for its size. Its watts can immerse the area around a dining table with music. See below for details on its power output.
