MMM again
Hereunder are 9 MMM measurements of the same loudspeaker (Behringer B2030A, with both LF, HF switches at -2 and -4dB) in 9 different rooms (10 to 30 m2 surfaces) at distances between 2 and 3m. It clearly shows that :
- under 300Hz, the room is the key
- between 300 and 800Hz, the room and the loudspeaker are both important
- above 800Hz, the loudspeaker is the main factor. The response is the same but the slope depends of the distance and the room absorption
