Center Channel Stand

I built a new center channel stand today which has an adjustable tilt. So I can precisely angle the speaker up towards my head when the center channel is laid horizontally. I've been using the center channel vertically because it sounds much better when sitting directly in front of it, but this does mean people off-axis don't get as good of sound. But now I want to lie it horizontally again because I also lowered the projector screen. I lowered it by about eight inches after making sure people in the back row will not be blocked by the front row heads. This screen height is much more comfortable for the people in the front row.

The center channel stand is made of two 10"Wx24"L pieces of shelving, and an odd connection between them. One of the shelves serves as the base. To this I attached two 8" angle brackets in the center, lengthwise. The top shelf had two pieces of 2"x6"s screwed into the bottom so that they would fall right inside the angle brackets rising from the base. I could then shoot a 5/16" hex bolt through the angle brackets and through the 2"x6"s. Now the top shelf can freely rotate using the hex bolts as its axis while the base remains flat. To lock the shelf's angle, I can tighten the hex bolt and nut, and I placed locking washers on both sides of the 2"x6" to keep it tight.

It's works very well, although you have to be certain to tighten the nuts and bolts enough to prevent the stand from rotating while the speaker is on it. I used some mounting stickies to keep the speaker in place on the top shelf. To put the stand at the correct height, I bought some 6" tall cinder blocks and placed them on the floor below covered in some leftover black felt. I spraypainted the wood and the brackets black to prevent reflections, although I didn't spraypaint any of the nuts, bolts, or washers because I didn't want them to get thick with paint or stuck with paint either.
