Greetings. I know this topic is covered quite a bit but I am looking for a little help. I currently have a Sony STRDA2ES receiver with Polk RT800's and an Infinity BU-2 sub. I cannot seem to find a good setting that satifies me when it comes to the high pass filter on the receiver and the cuttoff on the back of the sub. I currently have the sub freq turned all the way up and I have the receivers high cut filter set at 80hz. I am using the receivers LFE output. Can anyone tell me if the way I have this setup sounds correct? (I know it's not the "Polk Way") I have the sub in the right corner of my room behind my right speaker. I do get quite a bit of bass but I can't seem to find a nice blend of both mids and bass. Any suggestions would be appreciated. Thanks!
