Speakers or drivers for an non heated garage

Canada is a big place and you guys have a special kind of cold (in NWT, etc), sooooo...judgment prevents assuming temperatures.

In Canada "cold" also ranges from +2C and horizontal rain in Vancouver to "the propane has gelled" cold in Yukon, NWT, and the like places. It would be nice to know in which end of the spectrum OP finds himself and also if the shop will be used during those temperatures.

I would have concerns about any type of suspension much below freezing for example. Rubber gets pretty hard below -25 or -30.
