EXTRA BASS™ adds power to every bassline

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 optimises how sound is processed to stereo sound, 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.

Pump up the atmosphere with speaker lights and Party Light via Fiestable

The GTK-XB72 has built-in multicoloured LED line lights on the front, sides and top of the speaker, and a flashing strobe light for added impact. Just tap Party Light via Fiestable on your smartphone and the phone’s display starts to mirror the sound system’s lighting effects, flashing and changing colour 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. 

Customise 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 favourite playlists from your phone or a USB, and cue the next song without being tied to the sound system.

Fun, easy control via the Fiestable app

The Sony | Music Center app lets you control music and sound settings right from your phone. Plus the Fiestable app puts you in charge of the light colours and lets you activate DJ and karaoke modes. Make changes with a flick of your wrist, thanks to intuitive motion control. 

DJ effects let you put your own spin on tracks

Get the crowd going with a range of DJ effects: Flanger creates a distinctive sound effect similar to the roar of a jet plane; WAH automatically moves the frequency of a filter up and down; Isolator singles out a specific frequency band; and PAN sweeps the sound across speakers. You can get creative with sampling and scratching effects too.

Seamless streaming with NFC and Bluetooth®

Near Field Communication (NFC) and Bluetooth technology remove the need for wired connections and complex set-up sequences. Simply 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.

USB port lets you plug in, play and charge

With a USB port, you’ll be able to plug in a USB memory stick, smartphone, tablet or laptop and play all your digital files. Compatible with MP3 and WMA formats, you’ll be able to keep the party moving with your favourite playlists – and charge your device at the same time.

Expand your sound system with Wireless Party Chain via Bluetooth® technology

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.

Wirelessly connect another speaker for stereo playback

With Speaker Add function you can wirelessly connect two GTK-XB72’s via Bluetooth. Then choose from double mode, where both speakers play the same sound, or stereo mode, where one speaker plays the sound on the right channel while the other plays the sound on the left channel for stereo playback between the speakers.

Multi device connection

You and your friends can pair up to three smartphones or tablets simultaneously using Bluetooth technology. You’ll all be able to play tracks from your music libraries, giving you even more choice.

Built-in microphone for hands-free calls

When you need to pause the party to take a call, use the sound system, not your phone. A built-in microphone lets you divert calls from your smartphone straight to your stereo using Bluetooth connectivity. So you can make and answer calls without having to disconnect your phone from the sound system

Voice guidance keeps you informed

Voice guidance is a handy feature that keeps you updated about key functions: for example, when pairing your smartphone with the sound system you’ll hear “Bluetooth pairing” followed by “Bluetooth connected” once the connection has been established. 

Unleash your inner pop star

Sing along to your favourite tunes. A mic input makes the GTK-XB72 the perfect companion for karaoke parties.

Audio input

Audio input lets you connect portable MP3 players that don’t have Bluetooth® connectivity.

Built-in handles for easy portability

Pick it up and party anywhere. Whether you’re hanging out with friends at home or taking the party elsewhere, the GTK-XB72’s compact one-box design features built-in handles at either end for portability and convenience.

Take dance parties to the next level with this powerful one-box sound system. Combining EXTRA BASS and LIVE SOUND with vibrant LED lighting, including line light, speaker lights and a flashing strobe, it’s like being at a major music event. With Wireless Party Chain via Bluetooth® technology you can even add extra speakers for a bigger sound.
