Sony SRS XB32 Watts RMS

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

But what do the watts 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 watts RMS 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 watts RMS 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 SRS XB32, as a portable BT speaker, is a decently beefy model for its size.  Its tens of watts can fill a small to medium size room with clear music. See below for details on its power output.

Sony SRS XB32 Watts RMS: Notes

    1. The system tries to conserve battery power as the battery get close to total depletion.  The XB32 does this by reducing the audio output power somewhat.
    2. This speaker 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.
