Sea Pine Cottage living room with PLUTO loudspeakers

PLUTO is set up in a relatively large L-shaped acoustic space with different ceiling heights. At only 2 feet from the wall behind it and in a corner of the space the setup is not ideal. Still, the sound is impressive. Imaging improves significantly by pulling the speakers 4 feet into the room. The wall to the right and the open space to the left of the speakers does not seem to affect imaging. The speakers disappear, the tone is neutral and bass is in the proper proportion. The system does not have the clarity of the LX521 in the vista-room. Sound output is ample for the activities in the living, dining and kitchen areas.

4) - Interpretation of Data

 

 

 

 

What you hear is not the air pressure variation in itself 
but what has drawn your attention
in the streams of superimposed air pressure variations 
at your eardrums

An acoustic event has dimensions of Time, Tone, Loudness and Space
Have they been recorded and rendered sensibly?
