Description

These high quality sound projectors Projector Outdoor Speaker have been developed according to the lastest knowledge in aluminum or Plastic housing extrusion technology.

The sound pressure decrees nearly to the level of horn speakers

They have a high wide band, such as dynamic speakers, both of all models by aluminum housing or plastic housing have a built-in wide range twine-cone speaker, each of the integrated transformer tappings 100v /70v and also 50V have respectively three power levels.

An excellent sound characteristic and the dynamic of those sound projectors gives best results for speech articulation as well as for a very good music performance.

It is possible to rig up a number of these sound projectors, on top of each other, by use of similar phasing of the signal connection.

This effects a narrowing of the vertical transmission angle at 1/4/8 kHz.

Which has the same effect as a column speaker. Of course the aluminum & plastic housing are both able to be low-impedance connected.


Features for below of consider

Both models are established in an equal design , scratch resistant and impact resistant aluminum or plastic material.

The form and interior equipment of the sound projectors is configured , so that the favoured polar pattern of sound radiation is assured.

The required connection or impedance mode is done with clamp insulated wires.

The cable is led out at the rear side of the unit.
