Hi Have just purchased a sub for my system and wonder if anyone could clear up some confusuion as to how the combination of settings affects the output from the AVR300. I am finding setting up the sub far harder than any other part of my surround sound set up. I will still be using stereo direct for music so the sub will be for movies only. I am aiming for bass "extension" not more bass, providing a seamless improvement to my pre sub set up. I currently have fronts, rears and centre set to Large since a previous post by Andy Dutton suggested leaving these 5 speakers set to Large would maximise sound quality (as opposed to bass loudness). Am I right in believeing that with these settings ONLY the LFE signal will be sent to the sub, i.e. no bass redirection from the other 5 speakers regardless of where the sub xover freqency is set? In which case the setting of the sub xover frequency will have no effect on main 5 speakers, only the point at which the sub comes in? I saw in another thread that the specs for Dolby state that only frequencies up to 120Hz are included in LFE so if the sub xover frequency is set below 120Hz, any information in the LFE channel between the sub xover frequency and 120Hz would be "lost"? If I am right about the above (which is quite probably not the case!) would the optimum set up be Large setting for all 5 speakers and 120Hz setting for sub xover frequency? Thanks for any help - the number of possible combinations of settings on sub and AVR300 is a bit bewildering without advice on a decent starting point to begin experimenting from!
