I have just got a Denon AVR1705 and the SYS3AL speakers as a upgrade from a all in one system. As a bit of a seperates newbie, could I ask a couple of questions? 1. Any idea how low you need to turn the surrounds down if they are sitting on the back wall with the sofa (listening position) right next to them? I have guess ed at -5db but trying to find the same level for all speakers always misses me for some reason - I blame childhood ear problems. 2. Whats the deal with LFE vs SW levels? The manual states that 80hz is right for "small" speakers but I still get booming as the SW is a corner. I have turned down the level to something more neighbour friendly but do I need to worry about LFE? 3. The speaker wire that came with the kit seems high quality but thin. Should I worry about looking at upgrading it seeing as it is not exactly high end kit? Thanks (as ever) for help.
