Page 7 - The Concept
The CT 800 range comprises five products: CT8 LR A 3-way speaker intended for front left and right channels, one placed in vertical orientation at each side of the screen. CT8 DS A full range surround speaker that may operate in either 2-way dipole or 3-way monopole mode. CT8 CC A 3-way centre channe...
Page 9 - Planning the installation
Safety Warning! A CT800 system is capable of producing very high sound pressure levels. Prolonged exposure to high sound levels can lead first to temporary and later permanent hearing damage. Do not exceed recommended Leq (equivalent sound level) exposure levels, for example, those specified in ISO 19...

Surround speaker dispersion mode Surround speakers generally fall into two main types – those that one might describe as ‘normal’ speakers - so-called monopoles, where the sound comes from a set of drive units mounted on the front of the enclosure - and those that give a more diffuse sound field, suc...
Page 11 - Mounting the speakers
Mounting the speakers For optimum performance, it is important that the speakers are firmly and securely mounted. All the speakers may be mounted directly at floor level, but, as mentioned above, it can be beneficial to raise the position of the surround speakers and, if the screen is high, it may also...

CT8 DS Only Installation into drywall (figure 12) So that it can be sunk into a standard drywall up to the level of the side-firing drivers, the CT8 DS has a relatively shallow cabinet for its height and is front heavy. To maintain stability, it is equipped with a bracket that enables the rear of the ...

Description of controls The unit features a comprehensive set of controls to tune the performance of each speaker according to the conditions of use. The response may be shaped by a combination of three parametric equalisers, each having a level range of +4.5 / -12 dB, and low- and high-frequency co...

Running In The performance of the speakers will change subtly during the initial listening period. If they have been stored in a cold environment, the damping compounds and suspension materials will take some time to recover their correct mechanical properties. The drive unit suspensions will also l...
Page 28 - Aftercare
The speaker cabinet surfaces and the casing of the CT8 XO usually only require dusting. If you wish to use an aerosol cleaner, remove any speaker grilles first by gripping round the edges and gently pulling them away from the cabinet. Spray onto the cleaning cloth, not directly onto the cabinet. The ...
