Alan Shaw has discussed on Harbeth's forum about ambient temperature affecting test measurements. Temperature affects the stiffness of rubber surrounds in cone drivers, and also absorption quality of materials in the room (including insulation in the wall). So yes, room temperature does affect the sound.
Does room temperature affect your sound?
I am interested in hearing if you guys and gals have experienced a sound difference in your system under different room temps. We are now in a major cold spell in Texas and I don't seem to hear my system as clearly as I usually do. It is a little more subdued. Maybe it's my cold body and ears that make a difference. Anyhow, chime in if you have experienced sound at different temps. More specifically, is there an optimum temp for a vinyl TT system? Thanks.
