In-ceiling Speaker Installation

To install a Performance Series in-ceiling speaker, proceed as described in the following paragraphs and accompanying diagrams:

Separate the Speaker Module from its Installation Frame by gripping the tweeter arm and turning entire Speaker Module anti-clockwise with respect to the Installation Frame. Then withdraw the Speaker Module from the Installation Frame.

Having selected the installation position and checked for the presence of studs (joists), pipe work, ducts or cables, mark a cut-line on the ceiling using the supplied template. Check that the diameter of the cut-line is correct: 210 mm (814 in) for the P4-C65 and P4-DVC65, and 260 mm (1014 in) for the P4-C80.

Use an appropriate tool to cut along the cut-line to create a cut-out in the ceiling. Trial fit the Installation Frame in the cut-out to check clearances.

With the ceiling cut-out checked, the Installation Frame can be installed. Lift the frame into place and while holding it against the ceiling with one hand use the other hand to turn the three yellow securing clamps outwards and slide them down against the inner surface of the drywall (plasterboard).

Pull the speaker cable through the Installation Frame and ceiling cut-out. The length of free cable should be sufficient to allow the Speaker Module to be held in one hand while connecting the cable to the Speaker Module terminals with the other hand.

The speaker cable can now be connected to the Speaker Module. Strip 15 mm insulation from the cable (if necessary), twist the wire strands and insert the stripped ends into the appropriate speaker spring terminals.

If the ceiling speaker is a P4-C65 or P4-C80 model simply ensure that the positive conductor is connected to the red speaker terminal and the negative conductor is connected to the black speaker terminal.


If the speaker is a P4-DVC65 model it can be connected in one of two modes: Stereo and Mono.

Stereo mode

Stereo mode is appropriate if the P4-DVC65 is to be connected to stereo left and right amplifier channels. Connect the positive and negative conductors from each amplifier channel to one set of red and black speaker terminals. Ensure that the positive conductors are connected to red terminals and the negative conductors are connected to black terminals.

Mono mode

Mono mode is appropriate if the P4-DVC65 is to be connected to a single amplifier channel. Connect the positive conductor to the left hand red terminal and the negative conductor to the right hand black terminal. Use a short length of cable to connect the remaining two terminals together.

With the speaker cables connected, the Speaker Module can be lifted up into the Installation Frame. Take care that the speaker cable is positioned in such a way that it will not get trapped as the Speaker Module is secured into the Installation Frame and is not touching the Speaker Module in such a manner that it is likely to result in audible vibrations. Once the Speaker Module is fully inserted into the Installation Frame, grip the tweeter arm and turn the entire Speaker Module clockwise to lock it in place. It will click when secure.

The high frequency tonal balance of Performance Series speakers can be adjusted to suit different installation environments. A tweeter level switch located on the front bezel offers +3 dB, 0 dB and -3 dB options.

The tweeter module on the P4-C65 and P4-C80 can additionally be tilted to aim towards the listening position if desired.

In-ceiling speaker installation is completed by fitting the grille. The grille is secured magnetically and requires no more than placing into position.
