Just completed a full set of in-room measurements in 6 listening positions (individually) for each of these speakers, with independent measurement sets for each individual speaker (left vs right).
Speakers measured are:
Listening positions measured are numbered:
All measurements were taken with MiniDSP UMIK-1 calibration microphone connected to my Marantz SR7012 receiver via HDMI. All measurements were made with no changes to receiver volume level, so relative SPL between speakers should be valid as well. Each measurement consisted of two averaged log frequency sweeps (20hz to 20khz), for a total of 42 individual measurements (84 individual frequency sweeps).
