[QUOTE="Spurge, post: 543365, member: 14203"] @Naughty All points you make are very valid. The room is 4760mm wide x 7500mm long x 2500mm high. I did previously find it too long for a single pair of side speakers. I tried to solve it by placing 3 speakers on each side and running it through an old Pro-logic processor on each side so that I could fine trim each processors' Main Left, centre and main right and so create a "sound field" on each side. The "improvement" was not worth the trouble in my opinion. A switch to dipoles was much better and two direct radiating speakers on the ceiling reflecting off the side walls after splitting the signal on each side was slightly better than the dipoles. This was in 2005 using a Lexicon processor running Logic7. So it was a 7.1 matrixed through using the logic7 algorithm system with the same number of speakers as a 9.1 system. Now the option of 9.4.4 should address this. I have always liked the idea of having 3 subs where one is placed optimally along the width wall (on floor) of the room, the 2nd along the length wall (on floor)and the 3rd up against the height wall (off the floor). The intent is not to blow the window glass out of the frames. The 4th sub can be dedicated to smoothing room response where required. For me this is a theory. Have never tried it. [/QUOTE]
