ONKYO 606 and polk RM6750

[ttelivala]

Does anyone have a good set up for that setup. i have a living room about 15 feet by 20 feet and with the onkyo and polk setup i dont seem to get a loud enough sound until i raise the volume to nearly 50. Doe anyone else have any experience with that. I know its not about the loudness, but just wanted to make sure that i am not missing something. i ran thought the Audessey setup and also played with the individual setup of the speakers, but still seem to think that i am falling a little short.

any help would be very appreciated.

Thanks
