Bombard is an evolution of the basic model of floor standing Bassoon
loudspeaker. The principal differences lie in the use of a higher class
of transducers, the crossover filter components, internal wiring and
JAF Bombard represents an acoustic system in open, non-resonant
technology with asymmetrical dipole nature of sound propagation, in
which the radiation of rear side cone is obtained by a slit in
enclosure. The SFR technology (Smooth Frequency Response) allows to
obtain a low frequency range and high efficiency. The loudspeakers has
compact dimensions retaining the equivalent of 840cm baffle width.
In the Bombard model, four full-range transducers work with a diameter
of 21cm and magnetostatic ribbon tweeter. There are appiled broadband
drivers with stiff and ultra-light cone made of high density plant
fiber with a mass of 7.8g. The advantages are a proper pulse answer and
the correct transients reproduction.
Bombard loudspeakers are equipped with Room Gain Control module. This
solution allows to adjust the range of the bass , enables exact tuning
the loudspeakers to size of the room. In addition, independent
adjustment of each loudspeaker makes possible to adjust the stereo
balance of medium and high tones. Such need may appear in case of the
asymmetry of: the room, placement of diffraction or damping elements
and uneven of channels in other devices.
Single gold plated speaker terminals are located on the plinth. This
allows to use shorter speaker cables laid directly on the floor and
ensures safe operation. The standard internal wiring is made of a high
quality oxygen free copper with an area of 4mm2 cross section. The
essential components of the crossover is a high conductivity toroidal
coils and high pulse current carrying capability film capacitors.
The mechanical design is based on materials from MDF and natural wood.
Front wall, upper and base are made from the varnished MDF plate. The
material on the side walls is a solid wood of Merbau, Acajou or Oak
kind, coated with wax-oil that protects the surface. Finishes provides
matt effect. Side panels with a thickness of 35mm ensure the stability
of a narrow slit along the loudspeaker. The loudspeaker stands on the
spikes. Three support points ensure even distribution of weight,
without the necessary of the adjustment.
Bombard name comes from the folk musical instrument, whose roots go
back to Brittany. Bombard belongs to a family of woodwind instruments.
Bombard name is also used for organbuilding, defined as the pipes of
the reeds family stops.
