Beschrijving

Neodymium magnet assembly

Perfect acoustical coupling

Smooth frequency response

Very high sensitivity

800 Hz crossover

Extended high frequency response up to 20 kHz

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.
