The TN-24 loudspeaker is available in a 60°× 40° variant and in a 90° × 50° variant. The specified degree values refer to the horizontal and vertical radiation characteristics of the horn. Different interchangeable horn cones can be installed for this purpose. The variant of the T24N loudspeaker can be identified on the outside of the horn cone (see figure below).

By default, the HF horn of the TN-24 loudspeaker is oriented so that the horizontal beam angle is 60° and the vertical beam angle is 40°. In some situations it may be advantageous to change the emission characteristics in the HF range. You can replace the standard high frequency horn of the TN-24 loudspeaker with an optional 90° x 50° version. Proceed as follows:
Rotating the HF horn
1.Place the TN-24 loudspeaker on its back, with the speaker grill facing up. Make sure to place the speaker on a clean, non-slippery surface.
2.To remove the front grill, a hexalobular key with the size of TX25 is required. Remove all front grill mounting screws from the top and the bottom of the loudspeaker (4 pieces). Lift the front grill of the loudspeaker away. Secure the speaker against lifting and slipping if necessary with a second person.
3. Pull the horn with the compression driver up and out of the speaker cabinet.
4. Turn the horn funnel 90°.
5.Insert the twisted horn funnel into the horn foot. To do this, press the horn funnel until it snaps back into the horn foot with the click mechanism. Then check the tightness of the horn funnel in the horn foot.
6. Attach the grill using the screws provided. Please note that when operating the TN-24 loudspeaker without front grill, the HF horn must additionally be secured against falling out! (Sticking)
