Covering RPG Skyline with fabric

Of course it will work perfectly. Just use something similar to speaker grills - as near enough acoustically transparent as you can find.

Guilford of Maine is well known for acoustic fabrics. You can find a dealer or try direct - a web search will get you there. There fabric is used for a wide variety of acoustic treatments as well as speaker covers.

Whatever you attempt to cover the thing with, it will look even funkier. You know, what with the random length protruding blocks and all. Besides, better effort spent damping the thing.

I need to do it for purely aesthetic reason.They are pure white, and my front wall is painted in fairly dark burgundy color.
To paint Skylines?- too much work and messy, that's why covering them with fabric seems like an option

Or you could sell the Skylines and purchase the diffuser panels from Acoustical Solutions that are already fabric covered with many color options.
