Surround sound specific set up

5.1 Systems 

The 

twenty5

 series has been designed for perfect multi channel music or movie 

playback and the following diagrams display the ideal layout for the speakers.

   No doubt the constraints of room size and shape will vary the distances from 

the listener to the speakers. Therefore use of the time alignment function of your 
surround processor will be important.

   The guidance given in the ‘Stereo set up’ and ‘Fine tuning for perfect 

bass’ also apply to the set up of a surround system.

7.1 Systems

In a system capable of full 7.1 Dolby

®

 Digital Surround EX

, DTS

®

 ES

,  

Blu-ray

 or HD DVD

 playback there will be two sets of surround speakers.  

The first pair should be positioned at 100º and the second set at 150º. (The centre is 
considered 0º while directly to the rear of the room is 180º). See Ideal 7.1 surround 
set up diagram.
