Weak points:
- Spectral balance descendant: the heavier low can be corrected to the equalizer but not the severe lack of midrange
- Artificial spatialization
- Dynamic compression
Recommended Use: cinema (especially action movies), TV, radio ... but mostly no acoustic music
These speakers are not at all musical. The sound is so clean that it is "sanitized"! Listening to classical music, it seems that the microphones were placed at the bottom of a very large concert hall (not wired for sound). The sound is distant, disembodied, details and the top of the spectrum are virtually inaudible. On the Sibelius Violin Concerto (with the BSO Perlman), for example, the violin is lost in the middle of the orchestra, we no longer hear the sound of the bow, transients, harmonics ,,,
Technically, Bose used the tried and true recipes with a public who never listen to live acoustic music:
1. There is a built-in DSP, clearly stated on their website. This is already an aberration on the speakers with the analog inputs (A / D conversion and D / A). It clearly applies a spatial effect as my sound card can do it (environment "concert hall") except that the effect is not switched off the speakers. The DSP must also perform dynamic compression (such as FM radios) for the sound remains clean even on orchestral masses.
2. The speakers are physiologically equalized by digging the medium, but at a point where the upper midrange almost disappeared!
I much prefer my old Klipsch Promedia Ultra 2.0 which certainly saturate on strong orchestra and bass less firm, but have a medium and a strong and rich are much more transparent, natural.
