Does Storage Damage Equipmnt?

@bernadie5317 ”….has my system been damaged….?
 

Maybe your system was abducted by alien forces and genetically altered before return?

Great. As a starting place, cover the floor with a thick carpet in front of and back at least to the listening area. If you could photograph what is on the sides and in back, that would also be helpful. 

You will need corner bass traps. To simulate this you can pile couch cushions and dense pillows in the corners. Also, I see the acoustic panels. You might try covering it all with an absorbent thick wall hanging. 

Corner traps for the upper corners (these are cheap)... little triangular pillows. 

Have you experimented with toe-in yet?

I would not anticipate any humidity or temperature related damage in a typical storage facility after just a few months.  

Yes room is important some dsp can sound out the rooms and find the frequency problems.but letting equipment sit is like breaking in new equipment cardas has a great article on cables even if moved need more breakin time. Look at thier web site.also other articles have said same things.the compliance of speakers tighten up around the surrounds if not used and stored. Enjoy the science and the music.

If current system photo is the state of your system's room, then please consider some dampening behind/beside speakers, Speaker toe-in, and floor covering. In other words refection treatment(s).  Not expensive relative to other bits. Mr. Gorbachev take down that plywood.

If door doesn't swing into room moving L speaker move more to left should help too.
