hi, i have an onkyo ht-r500 that has only 3 crossover settings: 80, 100, and 120. my speakers are a jlb nsp1-II system. these satellites seem bigger than i assumed. almost the size of bookshelves. i also have a polk psw303 subwoofer. i plan on playing around w/ the settings, but where is a good place i can start w/.... maybe even something i can keep it at. set it at 80hz on the receiver and 100 on the sub? thanks.
