Large vs small ....LFE out...

Chadnliz,

Thanks for the explanation. I think I understand now. So in the manual this bass/lfe output option(per the manual) sends the bass of the "back surrounds" and where the .1 lfe goes...Seems simple. I just wonder why it is there at all if I have my mains set to large they get everything. The crossover in my speakers(which is at 80hz)sends those freq. to the powered subs in the speaker. The surrounds which are all set to "small" are (unfortunately with the Yamaha there is only one crossover) crossed at 80hz and that can be sent to the sub and or the mains.

My limititation is in my one individual crossover in the Yamaha. Tonight I am going to play around and try setting the mains to small and crossing over at 40-60. Allowing the Sub to handle everything below this...

I know its all subjective as to setting mains to large or small and what the sub should handle and I know what THX suggests. Just wondering what others have found best in their situations.

My set up is 80/20 ht. I am getting some very solid low end without any "boom". I've graphed out the room and have added some dyi acoustic treatments. Really, some quality move sound as far as imaging, transparency of the front end etc.

Initially, I was just using the Yamaha alone, but now as a pre/pro with Adcom 7ch which is night and day from the my initial layout.

glad to help, you have info on email if you wish to contact me......cheers

Your mains should not get any LFE (.1) info, unless you set them to Large, and your Pre-Pro to "no subwoofer". I have just gone through this, and discussed with both Cary and Denon to make sure when setting up my system to pass HT info through my preamp. I wanted to use just one sub, and use it for both HT and 2 Channel, but the only way to do that, practically, was to set the PrePro to "no sub", send all of the info through the 2 Channel preamp, then cross over the sub between the preamp, and the amps for the front speakers. So then I would be processing the signal after the tube preamp. I just got another sub instead.

I hope this helps.

Your probably going to confuse the issue aa you are only half right so I will make a point once again, The Yamaha unit allows for LFE to go to mains set to large if desired but you have a choice to just get a full range signal on mains if set to large with the sub doing the LFE.
