Industrial Horn Speaker

The LCS 70T has been specially developed for use in tunnel applications. The LCS70T is a typical exponential horn suitable for use at low ceiling heights or in projects where a large range of speakers is important.

The LCS 70T is made from a reinforced fiberglass-epoxy composite and features a powerful 2 "compression driver that can deliver up to 117 dB, and its shape and structure allow it to be used in demanding applications such as motorway tunnels or parking garages Voice evacuation is a good location for the LCS 70T.

Due to the dimensions, the effective range can be between 40 and 70 m, which means that the project requires fewer amplifiers and delay lines than conventional horn speakers. This helps to reduce the overall cost of the project, and the lower number of speakers increases the Q factor, resulting in better intelligibility throughout the system.

The LCS 70T has an extended bandwidth of up to 8 kHz and can thus reproduce speech in situations where the acoustic conditions are unfavorable and the demands on the system are correspondingly high in terms of high quality and fidelity. Speakers with high directivity require less amplifiers and signal processing, thus reducing the cost of the project.

The LCS 70T is a typical symmetrical exponential horn (the length of the horn is in exponential connection to the surface) which uses the mounting surface as a guide for the sound waves. This allows a "half cell" design to be used that reduces the required mounting height, which benefits projects with very low ceilings.

In the right frequency band for a certain size, the horn provides the driver with a relatively consistent acoustic load. This helps both the output level, the uniformity of the playback of different frequencies and is the property that makes this type of horns so effective.
