Frequently Asked Questions - WS624 Audac

What are the recommended cutout dimensions for the Audac WS624 speaker?

The recommended cutout dimensions are 245 x 158 mm. A template is included for easy marking.

How do I select the power tap for 100V line operation?

On the connection block, choose the desired power tap (24W, 12W, or 6W). Press the spring-loaded terminal, insert the wire, and release. Connect the common to the C terminal.

Can the WS624 be used with a low impedance amplifier?

Yes, connect the positive wire to the 8 Ω terminal and the common to the C terminal. This is suitable for standard low impedance systems.

How do I install the speaker in a wall or ceiling?

Cut the hole (245x158 mm), feed the cable, remove the front grille, rotate mounting clips inward, connect wires, insert speaker into hole, tighten fixing screws (quarter turn) until clips rotate outward and lock behind the surface, then reattach the grille.

What is the purpose of the small rubber pieces included?

The small rubber pieces are placed in the groove where the grille fits to prevent the grille from vibrating loose in high-vibration environments.

How do I remove the front grille?

Rotate the mounting clips outwards and push them down. The fixing screws will push the grille outward, allowing it to be removed.

What is the maximum power handling of the WS624?

For 100V line, the maximum tap is 24W. For low impedance (8 Ω), it is estimated to handle up to 30W RMS, but always refer to the amplifier's compatibility.

How do I clean and maintain the speaker?

Clean the grille with a soft, dry cloth. Do not use liquids or sprays. Avoid exposing the speaker to excessive moisture or dust.

Is the Audac WS624 suitable for outdoor use?

No, this speaker is designed for indoor in-ceiling or in-wall installation. It is not weatherproof.

What type of connection block is used for wiring?

The speaker uses a spring-loaded connection block. Press down to insert the wire, then release to secure. No tools required for connection.

Installation Guide

Installation Procedure

1) Cut a hole in the wall or ceiling on the desired mounting location of the loudspeaker with measurements 245 x 158 mm. The included cutout template can be used for marking.
2) Provide the loudspeaker connection cable through the mounting hole.
3) Take the loudspeaker, and remove the front grill. The front grill can be removed by rotating the mounting clips outwards and pushing them down. The fixing screws will push the front grill out.

4) Pull the mounting clips up again, and rotate them inwards, making the speaker fit through the mounting hole in the ceiling.

5) Connect the loudspeaker connection cable with the power tap connection block. On this connection block, several connections can be made for different power taps. Depending of the desired power, connections can be made for 8 Ohm low impedance application, or 24 Watt / 12 Watt / 6 Watt for 100 Volt applications.
Press the locking mechanism of the desired power tap down, and insert the connection cable. After releasing the locking mechanism, the speaker connection cable is connected to the loudspeaker or transformer.
Always connect the common of the amplifier output to the C terminal, and the positive amplifier output to the desired terminal. (8 For low impedance applications and the desired power terminal for 100 Volt applications).

6) Once the connections are made, the loudspeaker can be installed in the provided mounting hole. Insert the speaker in the provided mounting hole, and use a screwdriver for tightening the fixing screws. Once the screws are tightened by a quarter turn, the mounting clip will rotate outwards and will be locked behind the ceiling. From this moment, the loudspeaker cannot fall out the ceiling. To make the speaker equal with the ceiling, the fixing screws should be tightened.

7) Once the mounting screws are tightened, the front grill can be assembled to the loudspeaker. On locations where high vibrations may occur, it is recommended to push the included small rubber pieces into the groove where the grill fits in. This small rubber pieces makes sure that the grill won't come out by vibrations.
