Sony XB32 Power Output

The XB32 Sony Bluetooth speaker is a small to medium power, desktop style unit with plenty of audio power output to fill a typical room with full sounding tunes.

But what does the power output value a Bluetooth 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.

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, and as such, is of great interest to audiophiles and novice listeners alike.

In this case, the Sony XB32, as a portable BT speaker, is a decently beefy model for its size. Its tens of output power watts can fill a small to medium size room with clear music. See below for details on its power output.

Sony XB32 Power Output: Notes

1. The system tries to conserve battery power as the battery get close to total depletion. The speaker does this by reducing the audio output power somewhat.
2. The XB32 may not input enough enough power from a USB power 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 32 for an hour or two, to let it build up some reserve power while charging. Then, fire it up again for continued party enjoyment.
