I'm buying a new TV, which will be my first flat-screen TV for the home theater. I currently have an old RPTV, and our center channel speaker rests on a stand that supports it on top of the TV. Since that obviously won't work, with a new flat-screen, I plan to place the speaker in front of the new TV instead.
The problem is that most center channel speakers (mine included) are at least 5" tall, and the stands that come with most TVs these days only prop up the bottom edge of the screen by a few inches at most.
The model I purchased (that hasn't yet arrived) has a stand in the center, instead of the style that places one smaller piece at either end, so I figured I could cobble together a board to raise it up as high as I need to.
I plan to cut the boards to the size necessary (roughly 9" deep, 28" wide), stacked as high as I need (about 4"). I will glue them together with wood glue, and also fasten with some countersunk screws, and then paint the finished product to match our A/V stand (a shade of white).
First, does that sounds like a reasonable construction for such a platform?
Second, what type of lumber should I buy? Looking at Home Depot's site, I wasn't sure whether to choose from their Framing Lumber and Studs section, or the "Appearance Boards" section. I liked that the framing lumber would come in nominal 2" thicknesses, which means I might be able to get away with fewer laminated layers. But the "appearance boards" seemed like they were more intended for interior use, and the "edge glued" varieties are supposed to stay flat better.
Since I'll be painting it, the grain characteristics don't matter so much. But it's very important it not warp, and that it can support the 55 lbs the TV weighs.
Allow me to add some more info to address the comments and answers.
We're not considering wall-mounting the TV or speaker in this room for aesthetic reasons. The stand of the TV is 8.5" deep and around 27" wide. Also, I'm planning on rounding over at least the front top edge of the stand with my router for a more finished look (and I might do all four top edges).
I hadn't considered stability, though a 55 lbs TV should hopefully weigh down a flat piece of wood enough that it won't slide. Should I consider any special coating on the bottom surface? A non-skid pad would probably make it at least a little wobbly.
