Using your JBL Professional Control 128WT in - wall loudspeakers is a breeze. First, use the included cutout template to mark the area on the wall where you'll install the speakers. Make sure the wall thickness is within the maximum of 32 mm (1.25 in). Cut out the marked area and place the speakers in the holes. Connect the wires to the screw - down Euroblock - type connector, ensuring the wire size doesn't exceed 14 AWG (1.5 mm)². You can then adjust the aim of the tweeter for the best sound direction.
When it comes to power, choose the appropriate transformer tap based on your system requirements. The speakers can handle different power levels, but don't exceed the peak power of 200 W to avoid damaging the speakers.
For maintenance, keep the speakers clean by gently dusting them with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Also, make sure the air cavity behind the speaker is within the recommended 40 to 80 liters (1.4 to 2.8 cu ft) for optimal performance. If you're installing in a new construction, consider using the optional WB8 Rough - In Frame for a more secure fit.
