Just returned from an extended visit to the “Old World”. Yesterday I decided to relocate speakers as a test after a long period of not using the system.
I relocated the woofer towers using audio arithmetic (Nordost paper) which resulted in the woofers 30 inches closer to the front wall (behind speakers) and 14" further from the side walls.
Mid/High towers/wings moved to hit a precise 83% ratio (distance from speaker to ears *.83 equals distance between speakers). Meant moving them 3 inches closer to the side walls.
Spent hours enjoying the results. Tight/clean bass and superb soundstage.
Happy days!
