Features
Applications
Lotusline SS15 loudspeakers are based on the new SSATM proprietary technology.
SS15 cabinets are great tools offering the sound designer a wide range of new possibilities as well for covering shadow zones that cannot be covered by the main
system, as for building FOH systems in theatres, clubs,
auditoriums, churches and all places where long throw is
not a mandatory parameter but, a constant tonal balance
with distance is.
SSATM technology is Lotusline’s answer to an old question:
How to build a high SPL, compact and configurable, true point source system?
SSATM cabinets are mathematically equivalent to a portion of a spherical segment
whose acoustic centre at the centre of the mother sphere. In more simple words,
SSATM cabinets are like pieces of orange, they can be used individually and can
also rebuild a complete fruit.
SSATM cabinets are perfectly arrayable without audible interferences, even in very
high frequencies.
Each cabinet can be used unitary for covering small areas or coupled with other
SSATM cabinets for larger ones.
The SS15 is an active two-way loudspeaker cabinet. The low-mid section comprises
a 15 inch high power driver loaded by a MVCTM bass reflex enclosure. The high
section includes a 1.4 inch throat (3" diaphragm) neodymium high frequency compression driver mounted on SSATMwaveguide that provides a 45° horizontal coverage and 60° (+15° up, -45° down) vertical coverage.
The loudspeaker enclosure constructed of 18 mm birch plywood with internal braces
remains free of vibration at extreme sound pressure levels.
The enclosure have 2 aluminum integrated handles on the sides and include 8 x M6
integrated nuts for rigging.
SS15 cabinets eliminate the need of extra downfill cabinets and can cover places with front stalls and balcony.
SS15 cabinets are designed for constant curvature vertical tangent array as well as horizontal constant curvature
horizontal tangent array.
Like other Lotusline products, SS15 cabinets are
equipped with all necessary points for an easy and secure rigging using proprietary accessories.
