Infinity Systems Alpha 10 Bookshelf Speakers

Infinity Systems Alpha 10 Bookshelf Speakers 


The Alpha Series takes advantage of Infinity's long history of speaker design, pulling technologies like C.M.M.D. (Ceramic Metal Matrix Diaphragm) drivers from much more expensive high-end lines for use in these speakers. That's why you get such great sound! The Alpha 10 bookshelf pairs a 1" C.M.M.D. tweeter and a 5-1/4" C.M.M.D. woofer in an small, sleek video-shielded cabinet. Dynamic, lifelike mids and highs, as well as significant mid-bass, flow from these little troopers. The Alpha 10s are a good choice for surround speakers; they can also be used as front and rear speakers in a smaller home theater system, or simply paired with a subwoofer and used as stereo speakers.

I must say that I was not satisfied with the sound performance of Infinity alpha 10. I say this because although the highs turned out to be pleasant, although a little metallic in some songs especially in the vocal songs. On the other hand I liked the bass because it was well controlled but weak. In audition tests, I cannot say the same with the musical passages and timbres of the instruments. The instrument stage had a distance that looked like the musicians were behind the stage, but the passages of the notes of the piano and the violin revealed me dead without life between the low and high octaves. The vocal range has a very satisfying timbre, but it could be better. The voices proved to be pleasant, but not divine enough to enter my soul. Summary: Good treble, but with a slightly metallic tonal presentation, in voices. The lows were weak but balanced, but not deep. The notes and melodic passages of the piano and violin reveal themselves to be linear without noticing vivid oscillations in the passages between low and high notes and vividly not captivating in my ears. I give two stars for the finish and designer of Infinity alpha 10 and 20. Musically, the columns do not have tonal balance. The treble works higher than with the intermediate range and to make the bass worse it is weak and does not contribute at all to the entire musical scale. This model did not encourage to keep in the list of collection of speakers of sound option.


Melodic passages of the piano and violin low and not very enveloping.
