YES! The SOUNDBOKS alone is great, but having multiple SOUNDBOKS is even better!
If you would like a louder and a more immersive sound, grab two SOUNDBOKS and connect them with a preamplifier, to ensure that the sound quality does not deteriorate.
You can also use a simple Jack-splitter (AUX-splitter), if you need a quick solution for synchronizing two SOUNDBOKS. Unfortunately, this solution does not support stereo.
No matter if you have a SOUNDBOKS 1 or a SOUNDBOKS 2, you will be able to connect them to one another.
Wireless/Bluetooth pairing of multiple SOUNDBOKS is not possible at the moment.
