Product Description

Tunnel Horn Speaker Designed to be used in place with restricted ceiling heights and where far throws are requested



Features:

The TLH-70T has been specially developed for use in tunnel applications. The TLH-70T is a typical exponential horn

suitable for use at low ceiling heights or in projects where a large range of speakers is important.

The TLH-70T is made from a reinforced fifiberglass-epoxy composite and features a powerful compression driver that

can deliver up to 129 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 TLH-70T.

The TLH-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 fifidelity. Speakers with high directivity require less amplififiers and signal processing, thus reducing the cost of the

project.

The TLH-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 benefifits 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.

The TLH-70T should be mounted against a large and flflat surface used as a guide for the sound waves. The small

horizontal opening angle of only 30 degrees guarantees that the Audio signals are not affected by lateral disturbances,

thus increasing the maximum possible distance between two horns.
