LDS SP-48



LDS SP-48 represents a loudspeaker technology based on the principles of the Homogeneous Line Source. A Homogeneous Line Source produces a plane wave front whereby all frequencies reach the listener at the same time.

The LDS SP-48 system is a special purpose unit designed mainly to solve problems with HIMID/HF coverage at obscured seats and as a delay system. The small size makes it easy to conceal and possible to mount where traditional speakers would stick out.

The LDS SP-48 system is the perfect match for a larger LDS800 main system and to complement  the larger SP-88.

Each LDS SP-48 is equipped with four Planar-Magnetic (ribbon) Drivers.

The Planar-Magnetic (ribbon) Drivers used in the LDS SP-48 employ an innovative high-tech diaphragm material called Kaladex®, from Dupont.

Each LDS SP-48 can be mounted either
horizontally or vertically.
