I never listen to any speaker in the garage, cold or otherwise. The measurement gear is in the garage and it removes the effect of the garage so it is not even material there. All listening tests are performed where I listen to my systems: my 2-channel far field and 2-channel near-field. It is an open space requiring lots of SPL to fill it. But it is no garage. And it is at normal living temperature.
Duly noted , thanks.
