Ecler BET ACOUSTICS MASS1015P Manual De Instrucciones página 11

The components and architecture used for each of the ways of the system are described below:
BASS FREQUENCIES
The MASS1015P system uses a 15" bass frequency loudspeaker. As is shown in the diagram,
the loudspeaker is inclined. Thus the distance between the axes of the various stacked acoustic
enclosures is reduced, achieving a greater resultant sound pressure level.
By means of the aperture in the central partition wall of the enclosure the volumetric space is
optimized as regards loudspeaker rear load, creating a labyrinth that creates backward motion for
maximum improvement of the in-phaseness of front and rear emissions.
If access to the loudspeaker is required for maintenance purposes, the protective grille is
removed and the loudspeaker removed from the front of the enclosure.
