MTD 112 5 06/97
At the largest distances, the energy in the low frequencies is fairly constant due to the
reverberating field.
The aiming of the loudspeakers can be adjusted in order that the maximum HF energy is
directed towards these areas, hence balancing the SPL attenuation with distance occurring
in the direct field.
At nearer distances, the off axis attenuation at higher frequencies provides a similar tonal
balance, the attenuation with distance being smaller. The coaxial axisymmetric sound
source therefore provides the optimum directivity to obtain an even coverage and a very
constant tonal balance in a typical semi-reverberating auditorium.
The experience of sound system design and installation that we have acquired throughout
years of practice has extensively confirmed this, and on this ground, we are firmly
convinced that coaxial axisymmetric loudspeakers designs are the best tools for designing a
multiple sources sound system.
2.2 ELEMENTS OF THE SYSTEM
a) The MTD 112 system comprises two main elements, i.e. the MTD 112 enclosure, the
MTD 112 LLCa line-level controller and it can be complemented by any subwoofer of our
range.
For operation, the MTD 112 system must also include at least a power amplifier, cables and
connectors. Although these are not necessarily supplied together with the system itself, and
not necessarily from the same supplier, they must be regarded as parts of the system.
