Notes about operating and storage temperatures for your L1 System
From the L1® Model II / FAQ
Can I use the system outside?
Yes. The system has been tested to operate in 32°F to 122°F (0°C to 50°C) temperatures; it can also be stored in -22°F to 158°F (-30°C to 70°C) temperatures. Take precautions in light rain to cover the back panel of the power stand. Keep water out of the air inlet slits inside the back panel, on the loudspeaker drivers or inside the L1 cavity on the power stand.
