How LIVE SOUND mode works
The speakers of the SRS-XB31 are carefully designed to give you a real three-dimensional experience. The blue lines show how angled speakers with new DSP technology send your music to a wider area, creating a festival vibe, wherever you are.
Dual 48 mm speaker units
A 48 mm speaker means a powerful sound and bass
Made with Mica Reinforced Cellular (MRC), the rigid and lightweight speaker cone contributes to the sound quality.
There's no fun without party lights, and the SRS-XB31's new line lights go around the speaker.
The SRS-XB31's flashing strobe adds the ultimate party vibes to your music.
Give your party the extra boost with Party Booster
Simply tap your speaker in different places to make different sounds—like a scratch, snare, kick drum and cowbell. Control the volume with force, tap gently for a soft sound or give it a good hit for a loud output.
