EXTRA BASS™ adds power to every bass line

Push the EXTRA BASS button to add some serious low-end power to your music. It works by reinforcing basslines to create deep, punchy bass. Simply press the button to activate the mode and be blown away by resounding bass.

Vertical and horizontal setting

A flexible two-way setup gives you great sound, wherever you place the system. Set it up horizontally for a classic boombox feel or flip it upright if you’re short on space. A built-in sensor optimizes how sound is processed into stereo, whichever setup you choose.

Just like being there

Hear your music in a whole new way – just hit the LIVE SOUND button and cleverly angled speakers and DSP technology send your music to a wider area. Bring your party to life with a unique three-dimensional sound experience, creating festival vibes wherever you go.

Light up the party

The GTK-XB72 has built-in multi-colored LED line lights on the front, sides and top, pulsing speaker lights within the main body, and a flashing strobe light for added impact. The perfect way to create a club-like atmosphere.

Customize your settings with the Sony | Music Center app

Take control of your settings with the Sony | Music Center app. Simply download it to your smartphone and enjoy wireless control of your music. You can adjust audio settings, select your favorite playlists from your phone or a USB, and cue the next song without being tied to the sound system.

Enhance the fun with the Fiestable app

The Fiestable app puts you in charge of the light colors and lets you activate DJ and karaoke modes using your smartphone. Tap Party Light via Fiestable and your phone's display will even start to mirror the sound system's lighting effects, flashing and changing color in time with the music. There's no limit to the number of smartphones that can join in, which makes for a unique shared experience.

Expand your sound system

Add extra power to your sound system with Wireless Party Chain via Bluetooth® technology. Connect multiple speakers wirelessly via Bluetooth® technology for a higher sound output. Activate one device to be the ‘Party Host’ and sync music and lighting so everyone’s dancing to the same beat.

Seamless streaming with NFC and Bluetooth®

Touch your NFC-enabled device to the sound system for a quick, seamless connection, then start streaming your music collection. No NFC? No problem. Connect via Bluetooth and you're ready to party.
