My room is not very big, 14’ x 16’.
My speakers are on the short wall, about 3.5 feet out, about 9 feet apart slightly towed in, I am about 8 feet back. I have acoustic panels in the critical spots in the room.
My speakers are Jeff Bagby’s "Kairos" monitors, sitting on a a pair of his "Kairos woofer modules". These are NOT subwoofers, they are designed to turn 2 way monitors into a 3 way system.
The Kairos, use SB Acoustics drivers, and besides incredible transient response, coherency, transparency, timbral accuracy, they are imaging and soundstage champs.
I get percussion from the back of the orchestra seemingly coming from 20+ feet behind the speakers, violins extending beyond the outside edge of the left speaker, and cellos and basses from beyond the outside of the right. The image and soundstage extend well beyond the walls of my listening room.
It sounds about how it would sound form say, 12-15 rows back at Disney Hall.
I have chamber ensemble recordings, that have such an open soundstage, and a 3D image within that soundstage, that I can ’see’ each musician. It seems as if I could stand up from listening seat, and walk among the musicians in the soundstage.
These aren’t mine, but mine are not too dissimilar. Except I have not finished the woofer modules, they are bare MDF.
