I recently purchased the Pioneer SP-FS52 towers along with the matching center which I received today.  When I attached the center channel i don't seem to be getting the same sound from the towers before i had the center.  Can anyone point me in the right direction?  it seems most of the voices are now coming from the center channel.  do i need to adjust some setting to get more sound out of the towers?  Any help is greatly appreciated. Thanks...Keith
