Is it my receiver settings or speakers?

[jmr27]

Hi there,

I have a Yamaha RX 710 and my Speakers are;

Polk M 40's Fronts
Polk M 40's Back and back sorround
Polk Cs10 Center
Subwoofer 2 Bic F 12's

I have to have my reciver turned up half way just to get these speakers to kick-in. is there a setting that enables the reciever to its potential?

This is for both music and movies..

Thanks.
