hi is this setup ok with a 308
One KEF PSW2010 subwoofer and four KEF HTS2001 silver satelite speakers.
picked up a cheap mordaunt short aviano 5 for the centre......
The kef speakers will be fine with the Onkyo reciever. Ideally you should look for the matching centre to get a good front soundstage. The MS centre may not be a good match for the KEfs and hence a the sound could change as it moves across the screen. MS speakers are also bright sounding so may not be the best match either for the bright sounding Onkyo.
