Note Commona is the two-way loudspeaker system with enclosed baffle-board. Middle-bass driver with paper membrane of a diameter 7,4 inches is used in the system. Tweeter used in the loudspeaker has soft dome from silk cloth of a diameter 0,98 inches.
Baffle-board of the NOTE Commona loudspeaker
is made up from MDF (Medium Density
Fibreboard) with sufficient quantity bonding
agent of a thickness 0,7 inch. Cabinet is
stiffened by the system of accurately designed
HDF and wooden reinforcements, ingenious
muting resonance, which originate inside the
cabinet duringreproduction. 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 surface.
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
without circuit’s connection. Input terminals are
gold plated all-metal euphuistic clamps for
conductors for the cross-section 0,23 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. Front plates of the
NOTE Commona cabinets are modified by the
specially designed textile foil, which aims
the absorption of an unsuitable resonance of the
loudspeaker drivers on the baffle’s front side.
Loudspeaker system Mona is recommended to be placed
on special "anti-vibration-dumping-absorbers" Com.Mona stand (NN SE).
