It coated Rs900 for two such brackets. Instead of stainless steel, if we do with mild steel, we can do in 600may be. I checked some models online around 1500 or 2000, they look nice but some reviews say they are flimsy. So didn't take the risk.
Main problem is my kid. She may push the speaker away. I also taught of glueing it with double sided tape. Adding a border all around with aluminum angle is another idea, didn't decide which way to go yet.
In any case, speaker won't be isolated from the stand (like mounting spikes) which is not ideal.....
In the last i will look into cosmetic area. May be a paint or a thick and strong colour paper etc
