Sony XB23 Power Output

Sony SRS XB23 speaker, the front top view.

The XB23 Sony wireless speaker is a small to medium power, desktop style unit with plenty of music power output to fill a typical room with tunes.

But what does the power output value a wireless speaker has, tell you about it? Firstly, the watt is a measure of how much power the speaker consumes or outputs. Plus, this metric is a handy comparison measure. E.g. Generally speaking, speakers with more power output tend to play louder than those with less. They cost more, have bigger batteries and chargers, along with larger drivers. They offer greater dynamic range, have a deeper bass response, and stereo versions and offer typically a bigger soundstage to listeners.

The Sony XB23 connected and finished charging.

Thus in general, the more powerful the speaker, the better it sounds, even at lower volume. You get better clarity due to higher accuracy reproduction of the bass, midrange, and treble content of the music. More available power could mean less clipping distortion too. So, the speaker’s power output is a primary indicator of speaker quality and performance. So as such, the power output figure is of great interest to audiophiles and novice listeners alike.

In this case, the Sony XB23, as a portable BT speaker, is a moderate level model for its size. Its audio power can fill a small to medium size room with music. See below for details on its RMS and peak power output.

Sony XB23 Power Output: Notes

1. The system tries to conserve battery power as the battery get close to total depletion. The unit does this by cutting the audio output power somewhat.
2. The XB23 may not input enough enough power from a USB-C power adapter to keep the battery from discharging when playing at full volume, depending on what you’re playing on it. So it’s possible that even with the unit plugged in, you could still see it shut down. Thus on the (rare) occasions that this occurs, just stop playing the 23 for an hour or two, to let it build up some reserve power while charging. Then, fire it up again for continued party enjoyment.
