LITTLE SUMO Monacor subwoofer box

   

 

   
The compact
force package
There is not sufficient space in
every room for large-size high
power subwoofers or standing
speakers of cupboard size.
However, a sufficiently large cone
area is absolutely necessary for
creating low bass signals which
are precise and dynamic and not
indistinct and rumbling. In the
range of max. sound pressure,
too, even the 17cm bass speaker
of longest excursion cannot try to
come up to a special subwoofer
of twice the diameter and a cone
area whitch is almost four times
larger.
In LITTLE SUMO such a 30 cm
bass speaker is accommodated.
Due to a refined combination of
active and passive crossover networks,
an optimized Q factor by
a series resistor and a subsonic
filter of the amplifier module, a
surprisingly efficient subwoofer in
an extra small cabinet could be
created.
The LITTLE SUMO is not only one
of the most clearly sounding type
but it is also capable of producing
levels which are not self-evident
even for speakers of twice the
size. For the space-saving completion
of high-quality speakers for
HiFi applications as well as home
cinema systems, this subwoofer
presents an optimal sound result.

SONIC Monacor subwoofer box

             

   
There will be no
lower sound
Home cinema applications and
modern pop music have something
in common: both are most
popular and both are the more
fun, the more powerful the bass
reproduction.
Especially in case of movies,
however, the bass reaches much
lower frequencies than in case of
normal music.
No matter which requirements
the bass reproduction of the
music system has to meet – the
Sonic can fulfill them all.
Very deep bass thunderstorms
come into being in a cabinet of
still moderate size for this purpose
which due to its special design
can only be recognized as a speaker
system at the second or third
glance. The Sonic can also be
used as a table (however, during
operation it should not be used
to put dishes and glassware on
it!).
Both the lower cut-off frequency
and the volumes to be reached as
well as the transient response
and dynamic power of the reproduction
reach top values when
using the Sonic which can improve
any high-quality system decisively.
The preferable active concept
allows the integration without
problems into every system concept
and every room!
