The LFE signal was set when you told the unit your speakers for front were large so they get everything, your sub will cut off at 80hz or so (the number you set for the surrounds). On my Rotel there is a sub setting for use with large speakers to tell it that you want the sub to not only do its duty with the smaller speakers but also do all LFE period even tho you have some set to large...just more bass. If you can set your unit like mine meaning you can set every speaker to a specific crossover then maybe you should set everything as small but your mains crossover at 40Hz to see how it sounds. Some like doing all speakers at 80hz no matter how well they will perform to follow what they feel is the best true THX presentaion which I dont agree with........I prefer to let all spaeakers do what they can safely handle if powered correctly. Cheers
Large vs small ....LFE out...
I thought I had this figured out but wanted get some other opinions. I currently have my mains and center set to large, 4 surrounds to small and the crossover at 80hz...NOW...I also have my Bass/LFE setting on my Yamaha directed to sub(other choices being: sub/mains,and mains only). I guess my question is, there must be a cross over setting for the bass/lfe. I looked in the manual for the Yamaha but no info...Any ideas? I am assuming it has to be pretty low. My LCR have built in subs and being set on large more than handle movie soundtracks. Just curious what benefits if any snding lfe to sub vs sub and mains....
