TL series
Dispersion
TL series enclosures are designed to provide relatively wide (70°) horizontal coverage. This allows the majority of live sound applications to be covered with enclosures placed individually to take advantage of this performance feature, for example either side of a stage in a pub or small club environment as shown below. The loudspeakers should be either mounted on tripod stands or supported on straight poles on top of
STAGE
It is possible to array TL series loudspeakers in order to achieve wider horizontal coverage and in these applications it is recommended that the cabinets be placed such that the trapezoidal sides are touching to ensure that the appropriate splay angle is observed. For guidance when designing a sound system, a 70º horizontal polar pattern equals an angle of 35º either side of the centre line at which the sound pressure level is 6dB down with respect to centre, (averaged over the whole frequency range of the loudspeaker). Thus a 40º vertical dispersion gives an angle of 20º above and below the horizon.
