Here, we discuss JBL Speaker Loudness. So these figures cover audio output power, and other tidbits that you find on common mid sized JBL Speaker models.
Moreover, it’s clear from these specs, that the JBL Speaker sounds pretty good. Indeed it plays loud enough, with its twenty watts of mono power. Plus, the passive radiators give more bass than models like the prior Flip 3. It’s loud enough to fill a medium size room, and can easily be heard around a small swimming pool.
Furthermore, even at max output, the lithium polymer battery lasts up to twelve hours per charge. But you probably want to avoid playing is at max for extended periods, as doing so is quite hard on the drivers. It can damage them thus.
And finally. the specs certainly do not bely the great features JBL put into this medium level speaker. Indeed, the USB-C charging system provides faster recharging times as well.
