Hi Johnny, the house is an old prairie style, rooms blend into one another creating what is essentially a 12 x 75 open floor plan. The listening area is at the front of the house, and is 12 x 15. D-15’s are placed just into a windowed bay area, with chairs for three. Our listening is not the usual as it is almost always with at least two, sometimes three people. Only one chair is on axis, the other two are closer to one speaker than the other in a triangle. Given the set-up each listener is at most 36” from a speaker, hence my concern about performance at low volume levels. Music runs from soundtracks (LaLa land/Silver Linings Playbook) thru Americana (AKUS/Carolina Chocolate Drops) to Alabama Shakes to John Hiatt/Prine with some Sacd’s thrown in of all genres. I’m thinking monitors would blend into the prairie style better than the big box floorstander and newer designed monitors might provide a better “up close” musical presentation than my D-15’s. The floor is wood with a basement underneath - no concrete. Appreciate your thoughts.
