LARA-80 / LARA-100

 LARA® is a 4-way symmetrical, cardioid, self-amplified line ar-

ray system with 6000Wrms power. LARA® has a linear perfor-

mance of 146 dB SPL MAX and a wide dynamic range making it 

an ideal system for large events. Thanks to the cardioid design, 

we achieve a rear attenuation of -15 dB in the range of 63 Hz – 

200 Hz.

LARA® incorporates 2 x 12″ woofers with a 4″ voice coil plus an-

other 2 x 8″ in cardioid configuration; for the midrange, it uses 

another 2 x 8″ speakers with 2.5″ voice coils. The high-frequen-

cy section is made up of two DAS M-78N compression drivers, 

with 3″ voice coils and a 100º or 80º horizontal dispersion wave-

guide. All the elements have been designed and purpose-built 

to maximize the system’s efficiency.

The LARA® class D amplifier integrates a switching power sup-

ply with power factor correction (PFC), ensuring maximum per-

formance and efficiency regardless of the mains voltage. Each 

amplifier provides 6000Wrms divided into eight channels, 3 of 

them in bridge mode to feed the 2 x 12″ and the two compres-

sion drivers. The remaining two channels feed the front 2 x 8″ 

and rear 2 x 8″ transducers.

The 3-point rigging system works for both LARA® and LARA® 

SUB, allowing us to hang arrays of up to 24 LARA units and 16 

LARA® SUB units. The FSS TM (Fast Set Splay) angulation sys-

tem allows angles to be adjusted in steps of 1º, from 0º to 7º from 

the stacked position, significantly reducing assembly time.
