The bassmen
Standing in the background, adding to the lower tonal spectrum, ELAC subwoofers cover the full range of audio performance according to individual requirements and room design.
App-based control interface
Simply pair your iPhone, iPad or an Android device with the new ELAC subwoofers and adjust the sound to your preferences. The ELAC app required can be downloaded free of charge. Now what is really clever about the system is that there are no complicated network connections necessary as subwoofer and mobile device communicate directly via BLE (Bluetooth Low Energy).
