Stereo Stand

I am thinking of moving my stereo to a better spot so that you can actually the display without crouching to the ground and to make using the remote a bit more reliable.  Currently the stereo hides in a couch side table and is crowded by a storage unit.  

I need a minimal structure that will work with hover over my subwoofer and provide some flat space by the window.  What I have drawn utilizes 2x2 and 2x4 cedar lumber in a simple fashion.  The legs pass through the cross members in such a way that the 'wobble factor' is taken care of with the joinery.  And to keep the joint from working apart over time I have used a single bolt as a fastener.  

A top has not been settled on but I picture something thin; plexiglass, copper pan, painted plywood? Probably what ever comes cheapest, copper is out then, but it would be sweet.
