ah now I understand thanks I thought spesker size (large, small)where different then hz.

Had the backs set to 80hz (all speakers/sub also set to THX 80hz)now put the back surrounds to 90hz, they seem not as loud anymore but backs are not meant to stand out like the fronts do, not that they where that before, there just not as noticeable now.
