Hi I have set my speakers all to small setting on my amp (Yam A1) on advice of numerous people of this BB. The problem is when watching a film I know quite well ( theres something more about Mary ) which I finally bought, there seemed to be a lack(spelling) of bass on the front soundstage. I am using big Cerwin vega's for my mains and a Paradigm CC 350 for my center. My sub is a Servo 15. Should the sub not fill in the missing bass from the front soundstage or is only the very low sent to the sub that is why I am missing the bass on the center channel? I had the same problem when I demo'd a Kef 200C in that it sounded ok but it lacked bass compared with my Paradigm CC350, so I gave it a miss. ( it was a tad overpriced at £300 for a ex demo speaker in my opinian) I have now turned the speakers all back to large but Iam not sure if there is anything else I could try. cheers Dave. PS I think the Yamaha A1 sends all the bass below 90HZ to the sub.
