Because Physics Happens!
Just having the theater inside a room, whatever size it may be, creates problems due to reflected sound and low-end/bass build-up within that space.
Adding acoustic treatments is a simple way to take a standard room from good to great.
Following are several basic ideas that can be used even with the smallest of budgets to help the overall performance of a theater or media room.
1. Put absorptive material behind the screen, (Fiberglass, Recycled Cotton or Foam)
This will take the front to back reflections out of play and works well on narrower rooms.
Covering the front wall with treatment that includes bass traps will increase listening pleasure and speaker performance. This requires stretching the front wall with fabric; see SA’s Stretched Front Wall solution.
2. Place fabric wrapped acoustic panels around the listening area
This absorbs the side wall reflections that arrive later in time to the listener and “Smear” the sound continuing to come from the Center Channel Speaker
These panels can also cover In-Wall Surround Speakers and create a more aesthetically pleasing environment
3. Avoid putting speakers in the wrong position.
Seems like a no-brainer but I see it all the time. Speakers are usually put in convenient locations and not in correct positions
Weigh the pros & cons of the location versus speaker type
4. Place seats at optimal positions, avoid worst places to sit.
Against the rear wall is a horrible place to sit! Home owners want as big a screen as possible so the seats are pushed back against the wall.
Bass builds up against boundaries (walls) and creates a very difficult listening environment. Bass is turned down to allow speech to be heard or the entire row suffers
If seats have to be placed against the rear wall, adding absorptive treatments to the back wall can help absorb the build-up.
