Note Cello is the two-way loudspeaker system with enclosed baffle-board. Middle-bass driver VOBA with CardisP membrane of a diameter 6 inches is used in the system. VOBA tweeter used in the loudspeaker has soft dome from organic polymers impregnated silk dome of a diameter 0,98 inches.
Baffle-board of the NOTE Cello loudspeaker is made up
from HDF (High Density Fibreboard) with sufficient
quantity bonding agent of a thickness 0,86 inch.
Cabinet is stiffened by the system of accurately
designed HDF and wooden reinforcements, ingenious
muting resonance, which originate inside the cabinet
during reproduction. Inner side of the loudspeaker
cabinet is effectively dumped by the thick film of
special masses on the base of “bitumen” that aims to
mute further remaining resonant modes onthe baffle’s
This solving method displays practically mainly during
reproduction in the lowest frequency spectrum. To
prevent standing waves and to optimalize the (working)
settings of the loudspeaker efficiency a special
melamine-polyurethane matter of a corresponding
volumetric weight is installed on the critical places
inside the cabinet.
Frequency filter (crossover) is always engineered with
the use of first-rate parts (special CABLE4YOU sealed
and baked air inductors, top quality C4Y metalized PP
film capacitors with high VDC, MOX resistors) without
circuit’s connection. Input terminals are gold plated
all-metal euphuistic clamps for conductors for the
cross-section 0,2 inch. For speaker interference
purposes for frequency filter there are used cables with
sufficient cross-section from CABLE 4 YOU production
inside the system.
Enclosures are manufactured by default of natural
veneer modification and surface finished with exquisite
Italian PP lacquer. Front plates of the NOTE Cello
cabinets are modified by the specially designed glass
composite with diverse customizabled colour tones.
On the face wall around speaker drivers is fixed special
designed (for reference loudspeaker modular system
VOBA Know-How) absorption material AUDIOBAC
(Audio Bandpass Absorber Compound), which aims the
absorption of an unsuitable reverberations from the
front side of the baffle board.
NOTE Cello are fitted as standard on specially designed
stands BASEBOY, which which aims the absorption of
an unsuitable resonance between the loudspeaker
cabinet and floor.
