38% best position? What if the room is angled?
Hi there,

I found on the RealTraps site that the best listening position is 38 percent into the length of the room, when measured from either the front or rear wall.
But... what if the sidewalls are angled?
Let me give you the room sizes;
length is 5,03 m (16,5 ft)
width is 5,90 m (19,35 ft) in the back, 5,40 m (17,7 ft) in the front!
hight is 3,73 m (12,23 ft) in the middle of the room

How much distance from the frontwall would be the best listening position?yingyang

The 38% is only a starting point, which you may/will find that moving forward or back will yield a better response. So just start there but know you might need to move a bit.

You can use the following to test your room to find the best spot.

The side walls are irrelevant because the 38 percent "rule" is concerned only with the length modes. But even in a perfect room, you still need to measure to find the best spot.
