RedSIinPA,

What you want can probably be fabricated from wood easily enough. If the speakers have a wood grain finish the 'ramp' could be stained and finished to match.

The 'ramps' could be attached to the wall and your hanging brackets for the speakers attached to the ramps.

There are a lot of variables. The ramps could even be made somewhat adjustable to give you flexibility in the aiming pattern. A picture or two would be a help if you're interested in farming out such a project. Of course a lot depends on what you're willing to spend. But isn't great sound priceless?
