The Ultimate Trapagon is as good as it gets – with a little acoustic treatment your sound system will perform at its absolute best.
In this design the cinema walls taper slightly towards the back whilst the roof gradually drops from the screen down to the rear of the cinema. The rear wall is then set slightly off square. In a finished room it is very difficult to see the changes but crucially the design stops sound waves reflecting back on the same path they originated from, resulting in a clear, easy to differentiate sound. The addition of some acoustic treatments also stops sound waves from reflecting too much.
