As long as the wall is not facing the sun for most of the day there should be no problem, in my area SE is to be avoided. I am selling a pair of speakers and if you look at the pictures you will see my wall of albums behind the chairs. That is an outside wall. Another issue will be weight, make sure you reinforce the floor if not in the basement.
record storage question
I want to install shelving along an outside wall to hold my LP's and CD's. Will the back of the LP's get too cold? Is this detrimental to the records being colder on one half? Thanks in advance. Joe
