IL CREMONESE TECHNICAL SPECIFICATIONS
SYSTEM:
3.5 way, full para-aperiodic vented box “Stealth
Reflex System, and “Zero Vibration Transmission” technology,
vibration transmission- decoupled from the floor, staggered low
frequency floorstanding loudspeaker system.
CABINET: “Rhomboidal diamond design”, distributed thickness
triple layer cabinet walls, damped with spread resonance
spectrum system and harmonic decay internal reflections.
Sub–structural ribs are strategically placed for total rejection of
spurious vibrations and standing waves control. Two double
“dampshelves” (from “The” experience), i.e. CNC anodized
machined Avional “vibration dampers” (on the top and on
the bottom of each cabinet) “stiffen” the column structures
reducing consistently structural micro-vibrations coming
from the cabinets’ walls and the transducers. The subwoofer
enclosure has been integrated in the main enclosure through a
new implementation of the Staggered low frequencies emission
technology.
TWEETER: Sonus faber “Arrow Point” DAD (Damped Apex
Dome, synthesis of the classic dome and ring transducer) H28
XTR-04. A Sonus faber designed 28 mm moving coil driver, with
Sonus faber’s vibration optimized mechanical interface. The
ultra dynamic linearity is given by the new Neodymium motor
system. Implemented with a natural wood acoustic labyrinth
rear chamber, a mechanical anti-resonator designed for this
application.
MIDRANGE:
Sonus faber M18 XTR-04. A Sonus faber designed
180 mm neodymium magnet system ultra dynamic linearity
midrange. CCAW wire is used on a composite former “eddy
current free” voice coil. The dynamically linear magnetic field
motor incorporates triple Kellog/Goeller rings. A special custom
diaphragm is made with a real time air dried non pressed blend
of traditional cellulose pulp, kapok, kenaf and other natural fibers,
developed according to the most natural sound. To further
inhibit any residual cone coloration we are using a transparent
viscous surface damping coating. The same way as the tweeter,
the midrange is decoupled from the main baffle board and
designed synergistically with its optimized “acoustic chamber”.
A special coaxial anti-compressor is used, designed to remove
cavity resonances and distortions.
WOOFERS:
Sonus faber W18XTR-12. A pair of Sonus faber
designed 180 mm lightweight “sandwich” cone structure
(high-tech syntactic foam core and two external surface skins
of cellulose pulp) woofers are integrated in an acoustically
amorphous “stealth reflex” chamber. Designed to blend
perfectly with the special midrange and, at the same time, to
have absolute definition in their range: the sandwich structure
with outer paper pulp skins has the same sonic character of
the midrange cone. A powerful long stroke motor system with a
1,5” controlled “eddy current” voice coil is implemented for high
speed, performance and linearity.
INFRA WOOFER: Sonus faber W22XTR-16. A pair of Sonus
faber designed 220 mm lightweight “sandwich” cone structure
(high-tech syntactic foam core and two external surface skins
of cellulose pulp) infra woofers are integrated in an acoustically
amorphous “stealth reflex” chamber. Designed to blend
perfectly with the special woofers and, at the same time, to
have absolute definition in their range: in fact using exactly the
same cone sandwich structure with outer paper pulp skins. A
powerful extreme linear stroke motor system with a 2” controlled
“eddy current” voice coil is implemented for the presence of the
lowest.
CROSS-OVER:
Non-resonant design, optimized amplitude/
phase response for optimal space/time performance. “Paracross
topology”. The impedance at low frequencies is controlled for
a clear and friendly amplifier performance. Double staggered
transfer function low frequency/room interface optimized
filter. Highest quality is used in terms of the components: latest
generation Mundorf “Evo” Oil and Silver/Gold/Oil capacitors,
Jantzen inductors. Cross-over: 80Hz - 250 Hz - 2500Hz.
FREQUENCY RESPONSE: 25 Hz – 35.000 Hz, Stealth reflex
included.
SENSITIVITY 92 db SPL (2.83V/1 m).
