== Interesting Quotations ==
=== Road Proof ===
From: Hilmar-at-Bose

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.

=== Extreme Cold: Operating L1® below -10° C  ===
From: MikeZ-at-Bose

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.

=== Extreme Cold Suggestions ===

Hi 

In winter, when the outdoor temperature is -39F, the school buses pick up the kids at the road. Unless the wind causes the wind chill factor below -40F then the kids can stay home.

Winter tours are common and most of the gear travels in unheated trailers. The biggest concerns:

* condensation forming on ice cold gear in high humidity environments
* condensation forming on the inside of gear that has ventilation holes in high humidity environments
* cable jackets cracking if uncoiled while still frozen
* plastic parts breaking from impacts while still frozen
* moving lights: attempting to operate gear driven items when the grease may be frozen 


In very cold weather I recommend:

* Getting to the gig earlier than usual to allow for gear warm up time.
* Leave the gear inside their bags or cases while it warms up in high humidity environments (extra warm up time will be required since the bags or cases act as an insulator and will slow the warming process).
* Handle the gear with extra care while it is in it's frozen state. 

In winter when I have afternoon gigs, I load the car at home in the morning and unload everything at my workplace. I reload the car just before leaving for the gig. This way it doesn't take long for the gear to warm up.
