In April 2023 discovered a formula in ML Classic ELS 9 instruction manual for inside room speaker optimal or precise placement. If not precise optimal placement then close to optimal or within one feet radius of ideal or perfect placement in the room.
Measure the distance of the wall in front of LP from ground to ceiling in inches. Multiply by 0.618 .Each Monolith front midpoint must be kept this distance from the front wall or wall in front of LP. Now you know the placement of Monolith lengthwise in the room.
Next calculation for placement from the sidewall. Measure total distance in inches between left and right sidewall. First divide this measurement by 18. Second multiply by 5. The result is the required distance expressed in inches from side wall to front midpoint of Monolith.
Please try to place Monolith in the bigger room in harmony with the above formula. May save you time and effort getting the placement precisely right.
