onkyo 705 and def techs

[gandytime]

First off let me say as a woman, sometimes it can be intimidating asking questions,on a male dominated forum, So work with me on this. I have the onkyo 705, when reading this forum most say to set your fronts to Full Band, which by the way are def tech bp10s and clr3000, but while reading on another site they say set EVERYTHING to 80hz, which will also turn on double bass, why such a difference? Is one just an opinion? Btw Audyssey set fronts at Full, also the 705 doesnt have large or small speaker settings.What gives with the different settings? Thanks.
