360 Party Sound carries powerful sound to every corner of the room. Four tweeters deliver clear sound to both the front and rear of the speaker, with two mid-range speakers for vocal clarity. Feel the bass sound, thanks to the large X-Balanced Speaker Unit. Together, they let everyone in the room feel the power of the music, wherever they are. Powerful Sound with X-Balanced Speaker Unit
Sony's X-Balanced Speaker unit features a non-circular diaphragm, for an increased surface area compared to conventional speaker units. The approx. 320 mm x 320 mm large woofer unit is designed for clear and deep bass sound. A Richer, Clearer, Deeper Experience
The non-circular diaphragm not only maximizes the area of speaker diaphragm, but it also increases sound pressure for deeper and punchier bass, less distortion and greater vocal clarity. Altogether, it elevates your listening experience.
When ULT1/2 on, and the volume level is set to 18, lighting off. Actual performance may vary from the listed time due to the volume, songs played, surrounding temperature, and usage conditions. Batteries are consumable products, and their capacity degrades over time as they age. Sony does not guarantee the life span of the battery.
There are 3 modes: ULT off, ULT1, and ULT 2. Default setting is ULT2.
