Temperature
Notes about operating and storage temperatures for your L1® System
From the L1® System FAQ
Storage
The system can be stored in -30°C to 70°C temperatures.
Conversions:
- Operating 0°C to 50°C is approximately 32°F to 122°F
- Storage -30°C to 70°C is approximately -23°F to 158°F
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.

Interesting Quotations
Hilmar-at-Bose October 23, 2003 referring to the L1 Classic[1]
All members of our group at Bose are either musicians or sound engineers (outside their day job), so clearly we know what "road-proof" means.
The system went through rigorous design tests, including 5000 insertion and extractions of the cylindrical radiator(tm) loudspeaker (that's a LOT of gigs & rehersals Wink).
Other tests are
- long term full power (in the "bunker")
- high temperature operation (the "oven")
- low temperature operation (the "freezer")
- 3-axis vibration testing (the "shaker")
- high/low temperature storage
- drop tests (including a 220-pound fellow jumping up & down on the power stand)
and many, many more.
And yes, there are drain holes in the bottom of the power stand to deal with the occasional beverage accident.

Officially we rate our products (and guarantee operation) down to 0 C. We rigorously torture them down at these levels in unimaginable ways to make sure they work perfectly during the cold and after.
But of course you are asking about -10 C. While we haven't officially fully tested down to those levels I am confident you won't have any problems. The speakers will certainly be fine. The powerstand and electronics will heat up quickly to above 0 C internally and be fine.
If you waned to be extra cautious, when you get to the gig just plug in the L1's and turn them on. Let them run with no sound ('idle') for a few minutes. As I was saying, this will bump the internal electronics temperature up to above 0 C.
