Acoustic treatment for side glass doors / please, need ideas.


Sadly, wife's home renovations forces me to move my audio system from the family room (not the best place anyway) to a small room but with side glass doors (sadly yes, BOTH sides). Room is small, 15"(L) x 10"(W) x 9"(H) . I was considering install drapes (maybe better, roller shades) because in that area cant have fixed solutions. I really need some advice here because this change can ruin my relax moments listening my records and having a glass of scotch.
Thanks in advance

Very easy and not expensive either. Buy white or room darkrening pleated shades. You can pull them up and down like blinds and they certainly soften the acoustics of a hard glass door. They look nice too. 
In addition to shades please consider adding something to damp the glass. The Marigo 40mm VTS Tuning dots are ideal for this purpose

If for for some reason you decide against drapes I have also had very good results addressing room acoustics with a lot of glass using the Synergistic Research ART system (the resonating bowls). This gets pretty expensive fast but it works well and looks very nice

if you check out my room (similar size to yours) you will see both of these methods applied to a large window (plus I also hung ASC panels on it as well)
Thanks folkfreak for your ideas, in other situation I can consider them but I need to make the room nice also so I think I need to go with the shades.
roxy54, sorry about my english but when you mention pleated shades you mean the ones that have a design that looks like a v regular and then inverted right?, basically no flat. What about thickness? material? any link of something that you recommend? thanks again both for the input.
