Characteristics and sound properties
The COUPLET LIGHT is
a compact D Appolito configuration shelf speaker. It can be used as a shelf-top
speaker or mounted on free-standing supports. In contrast to the original
COUPLET, this system uses two W 130 S 8 OHM as woofers. The tweeter and the
cabinet design with its flow-optimised BR 25.50 bass reflex tube have been taken
over unchanged.
The result is a speaker that maintains its linear characteristics right
across the frequency range. Due to the well balanced medium range, the fine
details of music reproduction, in particular, comes across particularly clearly.
The excellent omnidirectional sound distribution creates a particularly
room-filling music reproduction and clear location of each individual instrument
or voice. The lowest-range bass comes across equally powerfully. In short, the
COUPLET LIGHT is a speaker that is really good fun.

Plan de fabrication pour enceinte Visaton COUPLET LIGHT :
CONSTRUCTION
All the cabinet panels are cut from 19 mm
chipboard or medium density fibreboard, butt-jointed and glued. The chamfers on
the baffle can be applied with a power jig or circular saw set to 45° or applied
later using an orbital sander.
Next, cut out the openings for the drivers,
the bass reflex tube and the terminals.
Due to the small size of the cut-outs in the baffle, it is difficult to mount
the crossover inside the speaker cabinet. It would be possible to make the base
removable. However, it is easier to wrap the crossover in damping material and
place it through the lower cut-out in the baffle on the floor of the cabinet.
When you begin fitting the drivers, start with the bass reflex tube. In order to
be able to get the inner trumpet flange through the opening for the upper
subwoofer it will be necessary to carefully remove about 5 mm from both sides of
the flange.
Inner damping
The damping material is loosely arranged
below the bass reflex tube in the cabinet in such a way that the area around the
vent remains free.
