Technology
Applications
Lotusline LA series are based on the latest electro acoustics developments and
include SHMTM and SICTM proprietary technology.
Lotusline LA10V2 are line array modules designed for
variable curvature vertical tangent array, able build long
throw line sources.
SHMTM（Single Horn loaded Midrange） improve dramatically midrange bandwidth
and efficiency by avoiding multiple components dispersion and using collinear mid
and hi frequency horns layout.
First line array uses mid drivers on plane baffle. Small improvements in efficiency
have been made by using compression load midrange directly in the front common
waveguide, but creating irregularities in frequency response, and dispersion in characteristics due to the multiplication of components. Actually, coaxial midrange
equipped with rear standard HF driver is used in common acoustic chamber imposing a long path to high frequency waves. Lotusline Line Array uses the shortest
possible design by positioning the toroidal HF drivers in front of the midrange driver.
SHMTM technology reduces the total harmonic distortion both in high frequencies by
minimizing the length of waveguides and in low mid by increasing the radiating surface of the driver.
Lotusline Line Array are high efficiency systems, thanks to the entirely horn loaded
design, and the use of the best modern European custom build transducers. Combined with the true line source design of Lotusline Line Array, high sound pressure
levels can be obtained in long far field with the best tonal balance on the whole
system coverage.
The 60° horizontal coverage and 0° to 10° vertical coverage offer the sound designer the best versatility for any
precisely designed installation.
Lotusline LA10V2 are completely compatible with Lotusline subwoofers series and can be stacked directly on
anyone.
The new Lotusline LA series three points hanging compression mechanism also reduces needed floor surface
and saves installation time due to the straight vertical
array configuration used during setup. The final curvature is quickly and easily obtained when the system is on
its working position. By releasing the compression on the
rear point, Lotusline Line Array returns to the straight
vertical position in a few seconds and is ready for a fast
disassembly.
Due to its exceptional sound quality, its power capacity,
and its fast and easy rigging, Lotusline Line Array series
are intended for daily use in touring companies, as well
as for permanent installation in theatres, congress centres or arenas.

Lotusline LA20V2 are line array modules designed for

LA20V2 perfectly complement LA10V2 line sources for
downfill.
Composite arrangements of LA10V2 and LA20V2 are the
best solution to cover any large audience area homogeneously.
Lotusline LA20V2 are completely compatible with Lotusline subwoofers series and can be stacked directly on
