Room response

What actually reaches the chair: every speaker in this room, each its own design at its own position with its own delay and bass management, summed coherently — plus a curve for each room ticked for comparison. This is the only chart carrying room effects; every speaker chart above it is free-field, because placement belongs to a room and not to a loudspeaker.
