new to all this information so bare with me...went out specifically to buy the bose series 10 5.1 speaker package. have had an awsome sounding Kenwood VR606 system for years, but looking to upgrade & relocate speakers to the walls. kenwoods too big & no mounts. install rep at Circuit city lays on a spew that i get more bang for the buck & save $$ by using Polk to add to VR606. i went with it. very dismayed at first that there was minimal instruction info & no speaker wires. out of frustration over set-up choices, i came to this site. BOY...have i gotten an education!!! never really knew what all the settings & possibilities were about. just thought even sound and booming bass was the ticket. anyway, a few questions. i hooked up the sub via front channel inputs & out to front speakers. center & rears from their perspective receiver outputs. now...what is the switch on sub labeled "rev/norm" relate to? i only have "nmnl/large/off" on center output set up. only way to change settings for rest of system is via testtone adjust or distance adjust. i have been reading up on the education site, but not clear on copnfigurations. by the way...small 15x13 living room w/ plasma tv & receiver directly accross from couch/listening position against windowed wall. anyone with similar scenario? oh, rear speakers brackets would not allow speakers to face each side of couch, so i made a cool set of mounts using supplied brackets and bent threaded rods 90 degrees. sorry for runnin on but tryed to supply as much as possible. thnx for any help.
