I am looking to add some diffusers to my front wall and I need to hide them when not listening.  So I need them to be easy enough to move.  And I think it might be advantageous to have adjustable height as well because I would to raise them up 1.5 feet, then lower down and store when not in use.   I know about the Real Traps diffusers and stands, but I don't think I can afford their diffusers.  The cost would be $1200 for a pair compared to 2 pairs of the D1's at $400.  After recent bass traps purchases, I don't have the funds to splurge, as much as I would like to because they look very kewl!
So I am thinking of getting GIK D1 diffusers and mounting them on a lightweight panel, two per panel.  I imagine I could use the Real Traps stands with this design too, but I'd like to find a more affordable solution (two RT stands would cost around $200 shipped).  The D1 diffusers are very light, 9 lbs a pair.  Add a rigid but light wood panel for mounting the D1s, so maybe total weight is about 12-15 pounds each side.
Any affordable suggestions for adjustable stands that I could secure to a wood panel?
