[QUOTE="Blackjack, post: 184107, member: 13343"] According to the speaker placement formula for this room "they would be placed on the narrow end of the room at the room width divided by 18 x 2 and room width divided by 8 from the rear wall and each other. (rw/18) x 5 = speaker to side wall. (rw/18) x 8 = speaker to rear wall and speaker to speaker. All measurements are to center of woofer". My room width is 6577mm / 18 =365,38 x 5 = 1826mm - from side wall 6577mm/ 18 =365,38 x 8 = 2923mm - from wall behind speaker If this speaker placement calc is correct then the distance between the speakers in my room would be 2925mm. "The traditional listening position is called the Nearfield Listening Position. It is where your head is at one point of an equilateral triangle and the speakers are the other two points" Theoretically the Nearfield Listening Position for the centre of my forehead would be 2925mm equidistant from each speaker. Ok, lets assume that I place a 3 seater couch at the Nearfield Listening Position I would be sitting 2923 (fr wall to speaker) plus approx. 2500mm (Nearfield pos) = 5423 from front wall and approx 3127m from rear wall. To conclude, my NLP will be 5423 back from the front wall and 3127 forward from the back wall. Attie, using this information, how many decibels would I need for a soft, moderate and loud volume.....remembering that I am only sitting 2923mm from each speaker and I would like to keep my eardrums intact ::) [/QUOTE]
