How to listen speakers? [step-by-step]

1. I suggest, listen speakers in usual position (like it shown in speaker user guide).
   Speaker have apperture (angle dependency of frequency response). So different positions can cause different impression.
    
2. Listrening room is very important matter. It should have middle of high sound absorbtion. Don't use rooms with many glass and ceramic surfaces.
    
3. As test stuff, I recommend:
   - bass note sequences from lowest to almost midrange.
   What listen: Resonances, how notes are separate.
   - cymbals.
   What listen: So callsed "send". Distortions on high frequencies.
   - trumpets.
   What listen: "Oil" in sound.
   - stick on snar, acoustic guitar.
   details so touch to instrument, scratches of strings, attack of notes.
   - classical compositions with very loud and quiet places.
   check  sound "transparency" and so called "air" on quietest level places of a tested musical piece.

Number channels is not matter. Before listening multichannel system should be adjusted/calibrated (if you like calibrated sound more).
