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.

Just an addendum to say there are a couple issues with glass doors and windows. There’s the fairly obvious vibration issue which, like room walls, can be dealt with a number of ways. But there’s also the RFI issue that might be less obvious. I suspect tiny little bowls will help with RF, although that’s not obvious. Maybe other things, too...Plus one can try to protect electronics from RF once you’ve allowed it into the room through the windows. Not to mention reflected acoustic waves.
Re Marigo VTS Dots: Marigo Dots come in various sizes depending on application - from capacitors to circuit boards to electron tubes to speaker cabinets to walls to windows. The dots operate via constrained layer damping. To whit,

”Beginning in the early 1930s a variety of theoretical and experimental research has been published regarding the development and use of damping. What began as an experiment to reduce noise and vibration in metals and plastics has become a common treatment in an amalgam of applications. Constrained-layer damping (CLD) is a specific method of treatment commonly used in the aerospace and military industries. CLD may be described as a type of shear-related energy dissipation achieved by interconnecting two or more structural materials using a relatively thin viscoelastic layer. Among the advantages of using CLD as a damping treatment are the ability to obtain high loss factors with relatively thin configurations and that the stiffness of the composite system is not markedly increased.”
