Note (internal)

• Height adjustment: Source 2 (ALLNET) states 15 cm, Source 1 (Icecat) 150 mm (equivalent to 15 cm), Source 7 (web search) indicates 120 mm to 150 mm. The value 15 cm (150 mm) is considered consistent.
• RMS speaker power: Source 1 (Icecat) states 4 W, Source 2 (ALLNET) 2x 2 W (total 4 W). No contradiction.
• Tilt range: Source 1 (Icecat) states -5° to +23°, Source 2 (ALLNET) +20°/-3°. These values contradict. The value from Source 1 (Icecat) is accepted as primary, as it is more detailed and aligns with the description. Source 2 (ALLNET) is considered incorrect or incomplete.
• USB hub: Source 1 (Icecat) states No", Source 2 (ALLNET) states "2x USB-A 8,1 cm ( 3,2 inch ). These contradict. Since Source 1 (Icecat) is considered official manufacturer data, "No is accepted as valid. The ALLNET claim is deemed unreliable.
• Weight, country of origin, tariff code, warranty: Not verifiable in sources, therefore not listed.
