Sony XG500 Watts Output, Input, Battery, Etc.

The SRS XG500 Sony Bluetooth boombox speaker is a medium power, party stereo  with abundant audio output watts to fill a common size room or yard with plenty loud, far reaching tunes.

But what do the watts of a BT speaker tell us about it?  Firstly, the watt is a measure of how much power the speaker consumes or outputs.  Furthermore, this metric is a handy comparison measure. E.g. Generally speaking, the more watts speakers can deliver. the louder can play. Plus, they sound bigger than those with less.  They cost more, have larger, heavier batteries and AC power supplies, along with outsized drivers.  They offer more dynamic range, have a deeper bass response, and stereo models like the SRS XG500 offer typically a bigger soundstage to listeners.

Thus in general, the more watts the speaker can drive, the better it sounds, even at lower audio wattages. You get clearer sound due to more accurate reproduction of the bass as well as midrange and treble content of the music. So, the speaker’s watts output is a key indicator of speaker capability and quality, and as such, is of great intrigue to audiophiles and novice music lovers alike.

In this case, the Sony SRS XG500, as a portable indoor / outdoor boombox, is a decidedly hefty model.  Indeed, its tens of watts can fill a medium size room inside or outside with easily heard tunes. See below for details on its power output.
