I'm after a pair of wall brackets for the "Mondrian" panel speakers - need to be shipped to Finland.

Yes, I know STBbrackets makes them, but I'm afraid I'd rather take the DIY route than pay quite that much... offers please

So easy to DIY

It would be easy if I had access to proper tools... It will be difficult to drill four holes in an exact straight line into a concrete wall of unknown quality, so I'd still rather have the original style slightly adjustable brackets (but not bad enough for £60 and the trouble of being stuck somewhere UPS can find me). So, query still on.

eBay used to be full of these when I didn't need any
