I have a Onkyo TX-SR504 AVR Polk RM6750 5.1 speakers. Connection is from AVR sub cable out of receiver left right rca splitter. Speakers set to small sub set to on. At the moment LF C RF are set at 3db LR and RR are set to 5db Sub is 3db crossover is set at 120. What is the max db i can use on these speakers not hurting them including the sub. And what would you set the crossover to, or what crossover is too high. And what happens when when i set the db higher, im new at this, never installed a surround system, so everything works fine just need help on theses settings. What setting would give me the best sound. It sounds pretty good when the volume is at 37 on the AVR. Trying to tweak the system a little more. Any help would be appreciated.

    Assuming you used an SPL meter or set it by ear, this is very close (+2 db for surrounds) to what I got using SPL meter for a very similar system.

    There's no need to use speaker level setup of your reciever instead of a volume control. Assuming your settins are correct (i.e. test tones from each of the speakers sound the same), I would drop LCR and sub to 0, and set surrounds at +2. Crossover should not be lower than 120Hz on the reciever and all the way open to the right on the sub to avoid double-filtering. Setting it any lower will make your small sattelites work too hard outside of their design specs.

    No need to tweak if it is already set correctly and sounds good.
    Run a search on this forum - I have found similar discussions when I was setting up my father's system.

    I will try these settings and see how it sounds. Thanks again

    Your settings work great for me, i like them better than my settings, only other thing i am waiting on is for CC to run the Polk 10" sub on sale. Thanks again
