The SUB S4 can suit all spaces, put it on display or tuck it away. Whichever you choose, your audio is unhindered.
Smart learning means that you only ever have to pair once. Turn the SUB off and your speaker will react by increasing its bass to compensate. Switch the SUB S4 back on and it will automatically connect again.
The SUB S4 effortlessly takes over the lowest frequencies, increasing the overall output of your speaker system. The result? An unbelievably big sound from such a small unit.
Subtle in appearance and striking in sound, the wireless SUB S4 is designed to blend into any environment. The SUB takes care of the lowest frequencies, leaving the DOCK E30 to take care of the mid and high range frequencies.
