Sony XB 20 Power Output

The Sony XB 20 Bluetooth speaker is a small to medium power, desktop style unit with enough music output to fill a common household size room with full 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 audio output 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 XB 20, as a smaller wireless Bluetooth speaker, is a decently loud model for all the bigger it is. Its power output can fill a room with crystal clear music. See below for details on its power output.

Sony XB 20 Power Output: Notes

    1. The system tries to conserve battery power as the battery get close to total depletion.  The XB 20 does this by reducing the audio output power somewhat.
    2. The XB 20 BT speaker may not input enough enough power from a low power USB AC adapter to keep the battery from discharging when playing at full volume, depending on what you’re listening to.  So it’s possible that even with the unit plugged in, you could still see it shut OFF unexpectedly.  Thus on the (rare) occasions that this occurs, just stop playing the 20 for an hour or two, to let it build up some reserve power while charging. Then, fire it up again for continued party enjoyment.
