Bring the energy, bring the party
Bring true energy to your party, with EXTRA BASS beats and party lights from the GTK-XB90. Incredible Infinity Mirror lighting takes visual effects to the next level, and a rechargeable battery lets you hold parties anywhere.

Feel the beat of EXTRA BASS™
Bring the dancefloor to life by activating EXTRA BASS™. It enhances the low frequencies of the track, for beats that get everyone moving.

The power to party anywhere, with a rechargeable battery
Got no mains electricity? The built-in rechargeable battery powers your party for 16 hours with the speaker lights off, and the volume turned to level 16. Even at full volume with EXTRA BASS™ sound and lighting on, you can party for 3 hours. If you’re running low, just activate stamina mode to make your battery last longer (up to 4.5 hrs).

Grab and go
Convenient carry handles make it easy to transport your GTK-XB90 from party to party.

More light, more excitement, more energy
Create an instant club experience, with pulsing strobe lights and coloured speaker lights that change with the music. Infinity mirrors are positioned around the speaker edges, bouncing light back and forth continuously to create an energizing party atmosphere.

  • Line Light – A multi-coloured lighting strip goes around the edge of the speaker.
  • Speaker Light – White LEDs move with the music.
  • Strobe Flash – A bright strobe lights up the dancefloor.

Add extra speakers, without extra wires
Want to boost your volume? Connect up to 10 compatible speakers with Wireless Party Chain for even more audio power and an exciting party atmosphere with synchronised lights. It's all done with Bluetooth® technology, so you don't need to use any connecting cables.

  • Connect with NFC & Bluetooth® technology – Create a one-touch wireless connection with your NFC-enabled device, or use your Bluetooth® settings to connect.
  • Plug in with USB – Access your MP3, WMA and WAV digital music files by connecting your USB device.
  • Add your own vocals – Be the party MC any time you want – just plug in a microphone, and you'll hear your voice in the mix (mic not included).

Control the party with Sony | Music Centre app and Fiestable
Run the party from the dancefloor, by using the Sony | Music Centre app. It lets you choose tracks, change sound settings and create playlists, all from your phone. The Fiestable plug-in puts you in charge of the light colours, lets you adjust EQ, or activate DJ control. Make changes with a flick of your wrist, thanks to the intuitive motion control.
