ELLIPTICAL WOOFER DESIGN
Capitalizing on the unique characteristics of an elliptical driver,the woofer assembly delivers superior
reproduction while offering the perfect profile for Sonance Silhouette’s design criteria. An elliptical
metal cone driver yields essentially the same radiating area as an 8" driver, but with a width of only
6". The undeniable performance of this drive unit delivers these unique benefits:
The elliptical design varies the distance from center to edge that contributes to the cancellation of
unwanted cone resonance. Resonance is a type of vibration that interferes with the accuracy of the
sound source.
The use of a die-cast aluminum basket provides a rigid, stable foundation necessary for correct
driver function.
Audiophile performance requires low distortion components during high cone velocity situations.
Those goals were met with the use of a light metal alloy cone,which combines reduced mass (weight)
with high rigidity to perform as a pure piston for predictably linear excursion.Acting as a heat sink
for the voice coil, the metal cone further contributes to the Sonance Silhouette's high power
handling capability.
An extended pole piece voice coil eliminates non-linearity coloration caused by common designs
that suffer from dust cap back pressure while providing active and effective cooling for the voice
coil assembly.
A high-compliance,half-roll rubber surround and long excursion enhance power handling.
BAFFLE DESIGN
The Sonance Silhouette baffle is constructed from 1" MDF. This material is known for its extreme
rigidity and non-resonant qualities.The high-gloss,black lacquer finish is applied to the baffle in a 10-
step process that requires five days of hand finishing. This process is similar to that used so
successfully to finish pianos and guitars. Precise, smooth driver openings ensure optimum
propagation of waveforms.
MIDRANGE, TWEETER DRIVER ENCLOSURE
The midrange and tweeter driver array is acoustically isolated from outside interference by its own
enclosure attached to the back of the baffle.This enclosure is constructed with a combination of three
different thicknesses of MDF to eliminate the mutual resonance occurring between the panels of the
enclosure. The enclosure is filled with a new synthetic damping material called Myraflex®
manufactured by Owens Corning, thus properly loading the interior of the enclosure.
