Introduction:

The BMS LA102ND is a high frequency line array transducer, designed to
produce a planar wave front from a 8”x1” rectangular throat.
It employs a pair of 4552 ND compression drivers coupled to a
special dual wave guide containing a common vertical slot to radiate a coherent planar wave front.

The 4552 neodymium drivers are mounted on a mutual aluminium heat
sink for increased power handling and reduced power compression.

What is the difference between LA102ND and 4510ND?

While the 4510ND Planar wave driver is a distinctive new transducer
engineered to radiate a coherent planar wave front from a
rectangular piston without internal diffraction the LA102ND use more
conventional wave guide design techniques to reshape the compression driver’s spherical wave front into planar wave front .

Application:

The acoustical performance of the LA102ND is very similar to a pair of
4510ND. The extremely high sensitivity and smooth frequency response from 800 Hz to 20 kHz together with the high power handling
makes the LA102ND the best solution for high quality, high SPL line arrays.

Compatibility:

The LA102ND is dimensionally compatible to two 4510ND units coupled
together, so the system can be upgraded later.

Two or more LA102ND units can couple together to create virtually
continuous line source.
