ACOUSTIC CHARACTERISTICS
The VIO Series has been designed with particular attention to the optimization of weight and size.
The wooden cabinet, coated in polyurea, weighs 63 lbs (28.6 kg).
The measurements are: 28.35 in (720 mm) (L), 12.3 in (312 mm) (H), 20.5 in (520 mm) (W).
The acoustic optimization begins with the careful choice
of the wooden cabinet's materials, shape and geometry.
There are several devices within the module that ensure
accuracy in a very wide range of frequencies.
In particular, the two 10" high quality woofers with
neodymium magnets and a 3" titanium compression driver
(1/4" output) are optimized thanks to:
1) two aluminum PHASE PLUGS (with diamond holes), which
provide closer low-frequency emission points by increasing
off-axis listening consistency.
2) sound insulation foam, used to remove internal reflections
of the phase plugs.
3) a waveguide designed to control vertical directivity in high
frequencies and obtain a cylindrical wave front.
These details ensure a perfect match between the modules,
thus allowing optimal frequency response for both long
distance and off-axis listening.
