It features a sophisticated audio system consisting of two woofers and two high-performance tweeters, delivering 100W RMS in AC mode and 70W RMS when running on battery. This setup ensures a wide frequency response from 44 Hz to 20 kHz, providing a balanced listening experience regardless of where you are. Built for durability and sustainability, the speaker is encased in recycled plastic with a grille made from recycled fabric.

Measuring 297 x 149 x 141 mm and weighing 2.1 kg, it balances a substantial presence with portability. Connectivity is handled via Bluetooth v5.3 for a stable wireless link. You can enjoy up to 24 hours of continuous playback on a single charge, and the Speed Charge function brings the battery back to full in about 3.5 hours. Additionally, the integrated powerbank function allows you to charge your smartphone or tablet directly from the speaker, ensuring your devices stay powered while the music keeps playing.
