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

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.
Pleated shades or a roller blind will have little to no effect as they are in practice acoustically transparent. It may ameliorate some of the excess HF but that’s about it. If you really want an acoustic impact you will need heavy lined drapes. I’m sure your significant other won’t mind the tuning dots so do think about them, they may foul the action of a sliding door however as they are quite thick

One other thought is to do as I did and use the ASC sound planks or GIK panels others suggest

I have them attached via velcro (hook/eye) tape. You can leave the velcro on the glass but only attach the planks when you are listening seriously. Again it’s going to end up costing you but this would work and be flexible
You're not worried about the glass glass which you use for your Scotch? It's a primary reflection point since it's in that sweetest sweet spot. 

Best place to start would be something like a Mapleshade brass or maple scotch tumbler.

On a serious note, I'm dealing with a similar issue. The far wall is mainly glass windows, and the designer just doesn't get it. I'll be using a 15-inch woofer as shield for the Tuesday battle, err meeting. Their recommendation is to do nothing...to let the beautiful light in. Since it is three against one, maybe 2 and a half since one of the designers is moderately sympathetic to the whole audio thing...anyways, you know where this one is going.

Curious to see what is recommended. I'm considering GIK free standing panels that can be moved out of the way easily. Though I'm sure I'll need to get designer sign off on the fabric color.
You might want to look at groffkait's website, he sells very small adhesive copper strips, that tune the glass, highly effective & inexpensive, work well with pretty window treatments.
Don't do anything until you've setup your system in the new room.  It reads as if you're speculating about a potential problem.  Wait until you find out if it's a real problem.
