Hi,
I'm hoping someone with a similar setup may be able to help. I've got the tsi500 as my right and left speaker paired with a cs20 front running them is an onkyo nr609 however the sound is really hollow when playing standard definition TV. Is it meant to be like this or is there a setting I can run to try and help. I've already run the audessy setting

Appreciate the help in advance
