Loudspeaker Sforzato is designed as two-way system with closed
enclosure. At design not only sound quality was of importance but
also appearance and conception of loudspeaker cabinet and support
NN1 as a whole. In set there is used middle bass speaker with dia
5,7inch and paper membrane painted with special dispersion paint
which is dashed in a special way.
This measure should avoid possible transmission of vibrations. There
is a tweeter with a 0,98inch silk dome. Both speakers are fixed to
enclosure in a special way developed by VOBA e.a.f.. This way
eliminates transmission of resonance from speaker to enclosure and
back. This solution enables for both speakers optimal working
condition and positive effect in whole frequency spectrum was proved
by many listening tests. All edges are rounded. This eliminates
eventual sound diffraction and sound reflection from front side.
Loudspeaker cabinet is made from MDF and natural massive wood
painted and stained with quality italian and scandinavian paints in tint
which was developed especially for this model.
For construction of inside part of enclosure a sandwich system
specially designed and by many tests proved was used.
System consists from three parts with total thickness 1,18inch and it
compensates acoustic pressures and feed back originated inside the
system. To prevent origin of standing sound wave and to set right
mechanical effectivity there is inside of cabinet special polyurethane
substance.
Front side of the cabinet is made from sandwich consisting f
rom five parts with total thickness 1,57inch. Back side of baffle is
made in the same way. Front layer of sandwich is from special
material GLASSBOARD (6mm thick) which has got optimal reflective
features. Back side of baffle is made in similar way where a pair of
gilded terminals is located enabling connection in all common ways.
Crossover (passive frequency filter) is fitted with top quality
components e.g. (backed wire coils with air core, MKP capacitors,
top quality cables etc.).
Wiring among all parts of passive frequency filter are made without
using printed circuit. Loudspeaker system VOBA Sforzato is
recommended to be placed on VOBA support NN1.
