Ball-proof wall speaker for AB cabling. Suitable for use in small rooms where the installation of two speakers is not possible. The ZL 135 AB-T3 is equipped with a 135 mm double voice coil speaker with an additional tweeter cone and two 100V/3W transformers. It can therefore be operated via two cables on two different amplifiers at the same time. If an amplifier fails or a cable is defective, the signal is still reproduced - albeit more quietly. The connection is made via a ceramic terminal and special strands, the transformers are equipped with a thermal fuse in accordance with the British standard. The perforated sheet cover is secured with two visible screws.
