LCR Speaker Alcoves - Right or wrong idea?
I’m building a dedicated theater in my basement. I’m in the electrical stage and will be bringing in the dry wall guys in a couple of weeks. Before they get here, I want to pass by a design question to this group.
While building the wall for my front speakers / screen, I put alcoves in the wall to hold my speakers. Now I’m wondering if that was a genius move or an exercise of an uninformed mind.
Let me explain the “alcoves”, why they are there and my intentions.
Disclaimer. I’m a smart guy but know nothing about theater design or sound waves. If these alcoves are going to ruin my sound, I’ll try to figure something else out.
I’ve included a picture which is hard to understand since you can see right through the studs. I’ve also included two drawings. One top view. One front view.
I built a wall to section off the two halves of my basement. One half will be a beautiful finished Home Theater. The other half will remain an unfinished basement that I will use for a gym. I wanted to make the theater as big as possible so I built the wall right up next to the Window of the gym. In other words, I can’t move the wall any further back into the gym because there’s a window there (Figure 1).
After I measured the room, figured out where my seating was etc, I was worried that the first row would be a little too close to the screen so I thought about how I could put the screen as close to the wall as possible while still having the speakers behind the screen. That’s where I came up with the idea for the alcoves. If I made alcoves in the wall, then the speakers wouldn’t take up any room in the theater and I could have the screen as close as 4” from the wall. This would give an extra 12”-16” of distance between the screen and the first row of seats.
Figure 2 is shown as if you were in the seats, facing the screen. You can see that while I was building my alcoves, I also raised them up off the floor a bit to help the sound get over the first row and because the second row (MLP) will be raised 14-15” off the floor on a platform.
As you can see from the diagrams, each alcove is:
• 14” off the ground
• 15” wide
• 18” deep
• 75” high
Please let me know if you think this will work. If I’m just an idiot for doing this, I’d rather try and do something to fix it now though the thought of completely tearing down the wall makes me want to cry.
