🔹 Pro Tip

💡 Power at 20–24 V for maximum output and clean headroom. Use good quality speaker cables and keep them short to minimise resistance losses at 25 W levels. The Bluetooth connection range is approximately 10 m — ideal for room-scale streaming.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
