Advance Acoustic UM-40

Come molti prodotti costruiti in  cina anche questo ha la caratteristica di dare tanta sostanza e qualità ad un prezzo veramente concorrenziale.   Disegnati e progettati in Francia , costruiti in Cina , un cabinet veramente ben costruito , solidissimo e con finiture ad altissimo livello.

L’impiallicciatura e in legno naturale  e il resto e di mdf di alto spessore lavorato benissimo il peso si aggira intorno a i 25 kg per diffusore !!!!!!!  Scusate se mi ripeto ma davvero la  costruzione e fantastica  per un diffusore di questo prezzo.

Dal sito ufficiale:

Advance Acoustic had decided to design the loudspeakers in three basic categories :
– Cabinetwork
– Speakers
– Filter circuit

Cabinetwork :
All Advance Acoustic speakers cabinetwork is made in medium due to its rigidity and manufacturing precision ; Moreover, partitions and strenghthening pieces prevent any vibration or interference. The internal volume of the speaker is worked out in minute details as are the dimensions of the tuning hole for every speaker used.

Speakers :
Advance Acoustic speakers are made according to specifications in a rigorous manner in order to meet with the wished-for results. Boomers are provided with a treated paper membrane in order to get a more neutral sound and pure copper moving coils are wired on capton. To prevent any harshness and enhance smoothness, tweeters have either plastic or impregnated fabric membranes. Moving coils are cooled in ferrofluid.

Filter circuit :
Despite the care brought to cabinetwork and the choice of the best speakers, the final result is determined by the filter. Advance Acoustic has devised an accurate rigorous filtering technique respecting the acoustic and electric phases. A choice of the best components, air selfs, polypropylene condensers, high standard ceramic resistances, non-radiant positioning of the componants and judicious cuts frequency.
