Your Pioneer surely will send the LFE(on DD or DTS 5.1 sources) to the front L/R speakers if you set it to "no sub", but you will need to set the front L/R speakers to "large". As others have said, I wouldn't try to crank it very loud with a receiver.
I am running like this with my Sony DA4ES and Legacy Signature II speakers with pretty good success. I don't get any where near "reference levels", however.
