E. Service

Regularly check the vents to ensure air flows freely 
in and out. Clean the foam rubber filters whenever 
necessary. Remove the vent grille on the back to do 
this.

2.  ConTour Array™   

Spare Parts

Note: 
•  If your equipment needs service, please turn 

to your HK AUDIO dealer or the HK AUDIO 
distributor in your country. They stock the 
required spare parts.

•  In the event of a defect, always indicate the 

defective device’s serial number. This way the    
HK AUDIO service team can immediately find out 
if an update is available for your product. 

•  Use only original HK AUDIO replacement speakers 

and parts! Most were developed especially for HK 
AUDIO products and are not available direct from 
speaker manufacturers!

3.  Replacing Loudspeakers 

and Voice Coils

3.1 1", 8" and 18" Speakers 

Proceed as follows to replace the given speaker:
•  Unfasten and remove the Phillips screws holding 

the grille in place. Remove the grille. These screws 
are on the CT 118 Sub’s front panel and the       
CTA 208’s side and bottom panels.

•  Unfasten and remove the hex head bolts holding 

the speaker in place.

•  The speaker is now detached. Disconnect the 

speaker wires.

Caution: When installing and connecting a 
replacement speaker, ensure the polarity is correct!
Red= positive, black = negative 

1. Maintenance

3.2 The Drivers’ Voice Coils

Proceed as follows to replace the drivers’ voice coils:
•  Remove the front grille as described above.
•  Unfasten the four screws holding the horn yoke 

and remove the horn and driver from the baffle.
Disconnect the wires connecting the driver. Ensure 
correct polarity when installing and connecting 
a replacement speaker! Red= positive, black = 
negative

•  Unfasten the voice coil housing’s hex head bolts 

using a 3 mm wrench.

•  Take the lid off the voice coil housing.
•  Replace the voice coil.

Important note: Replace the voice coil in a clean 
working environment only. Be sure to keep dust 
and dirt out of the open driver. If despite your 
precautions particles manage to get in, use a strip 
of adhesive tape to remove them or carefully blow 
compressed air into the back of the driver to whisk 
the particles out. When installing the new voice 
coil, ensure it is centered properly. Proceed as 
follows to check this:
Close the cover of the voice coil housing and 
reconnect the cords (red = positive, black = 
negative). Feed a sine wave signal with a frequency 
between 1000 Hz and 1500 Hz into the mid/high 
enclosure’s input. Sweep through the frequency. 
If you hear abrasive noises like crackling or 
scratching, the voice coil is not centered properly. 
Reopen the voice coil chassis and turn the voice coil 
a bit until it renders the signal cleanly!

4. Checking Speakers’ Phase

As a precaution, always check the components’ 
phase using a suitable phase-checker after replacing 
speakers. To do this, connect the CTA 208 mid/high 
unit to the CTA 118 Sub using a Speakon

®

 cord. 

Note: If you are checking the CTA 208 mid/high 
unit in passive mode with an external power amp, 
you will get a different phase reading! Therefore 
always use the CTA 118 Sub for phase checks.

Connect the phase-checker to the CTA 118’s signal 
input. It may be advisable to lower the input level on 
the DDO-Pro™ Controller!
The speakers’ phases should read as follows:

With CTA 118 Sub:
18" woofer: 

In phase (+)

8" speaker: 

Out of phase (-)

1" driver: 

In phase (+)

CTA 208 passive:
8" speaker: 

In phase (+)

1" driver: 

Out of phase (-)
