Components, Configuration and
Performances
The diffusion section uses high efficiency custom devices, engineered in the special configuration:
 2 x 8" w 1" compression driver with a 1.4" alluminium diaphragm .The connection of these elements offers signifi -
cant advantages for both the reliability and the acoustic performance, especially in the reproduction of the vocal range.
Some examples:
a. The double 8" woofer reduces the interacting masses by 30%
compared to the classic configuration with a single 12" speaker.
This leads to a higher acceleration factor (fasterresponse to the
transients), a wider extension toward high frequencies and therefore a
better acoustic continuity among high/low components of the system.
b. Using a 1" HF driver, made following the last generation technologies
and provided with a1.4" alluminium diaphragm (instead of a conventional
component provided with atitanium diaphragm), causes a much more
efficient high frequencies (105 dB) transduction, a wider frequency
extension, a better acceleration factor and a higher reliability.
c. The HF driver is assembled on a elliptical wave trumpet, designed for
being free from acoustic resonance and, at the same time, for being
characterised by a wide dispersion angle, an excellent quality of the
diffusion – even out of the axis – and a special intelligibility of medium-high
and high frequencies range.
All these characteristic provide an acoustic coherence that allows:
- The audience: to enjoy the same sound quality anywhere on the stand.
- The performers: to maintain a constant hearing perception, whenever the
loudspeaker is placed vertically, for monitor use, etc.
