[QUOTE="Vaughan, post: 52745, member: 693"] That's fine. I set up my own system this way, just so I know I have all the bases covered. Receivers have high and low pass filters for this reason. Even if no LFE track existed and each main channel had info down to 20 Hz, if you chose 80 Hz to be your high pass filter then the content at 80 Hz would be low pass filtered to the subwoofer out (if turned 'on' in BM). Even if the subwoofer had no internal low pass filter, the receiver has it's own LP filter. Of course, now we add in an LFE track which is bandwidth limited to 120 Hz. The LFE LP filter only limits the upper bass in the LFE track. Many receivers allow you to change the [b]LFE[/b] low pass filter. Most Onkyo and Denon receivers have this feature, I'm pretty sure the Yamaha and Pioneer models do as well, but I can't confirm that. The LFE content [i]plus[/i] all those small main channels will get low pass filtered and sent to the sub. Regards, [/QUOTE]
