Spatially intimate secondary system yet with reasonable scaling capabilities. Used mainly for relatively near-field (6') listening in a room nominally 11.5'w x 21'long x 8'-14'h in an open plan house. I do not advocate dedicated listening rooms. My hifis are out in the open living areas for people to enjoy, so no man-cave nonsense here. Also, no silly room treatments. If you can't get a normal domestic living space to sound good when recorded music is played into it, you're doing it wrong. This is also where components are vetted for consideration into my primary system.
