acoustic vertical window blinds

Does anyone have  recommendations for manufacturers or suppliers of room blackening/darkening vertical window blinds for use in my mostly audio room? On each equal length side of each speaker ( a bit over 6' ) there are windows, on one side a standard double hung, on the other a rather large 4 panel bow window (over looking a fairly lovely private natural setting). I may or may not stay in this house for very long, so I neither want to overinvest nor shortchange my listening pleasure. I need to replace the current vertical blinds, and thought my fellow Audiogoner's might have some suitable suggestions.

Thanks in advance.

One solution that will work better than any blinds or shades is to attach a number of ASC or GIK absorber/diffusers (like the ASC sound planks) using Velcro tape. This will be fully removable when you leave and you can also take it with you. Finally adding a Marigo VTS window dot to the glass will also help

Adding to Geoff’s description the window dots, which are actually quite large being about 2” across and 1/4” thick, when correctly placed help damp resonances in the panels of windows.

I also have HFTs (and SR ART resonators) on my window as well. Each of these tools serves a different purpose
1. The marigo dots damp the glass and make it more like a wall
2. The sound planks treat reflections from the glass/wall
3. The HFTs then focus the sound at the reflection points and make the glass/wall disappear

The good thing is all three are readily removable

ps my window is also an acoustically designed dual double pane setup without any parallel surfaces ...
