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

Ok, now I am even more confused...

Chadnliz,

So I understand that setting to large sends everything to that specific speaker. So when the Yamaha gives the choice of where to send the bass/lfe(thats how it is described in the manual) to only the sub or to the sub and L/R, it isnt crossing over at a lower pt, say below 40hz(ex.)? There is a noticable difference in sound..HMMMMM..This entire time I thought I had it figured out... I can tell you that the cross over to the subs in my speakers is 80hz per Owen at Definitive. ...

check your email,,,I sent your a message

I prefer crossing to the sub at 80 Hz. By themselves, my KEF 104/2s sound fine, well able to track a jazz bass down the fret board, but not able to provide that subtle more felt than heard effect when a low pedal note is invoked on a large pipe organ. My Velodyne HGS-15 provides that. Where I disagree with Chad is that I find using the 104/2s full range with the sub results in a bit less air and transparency than when they are limited at 80 Hz. It's subtle, but real. It must be due to double coverage of the under 80 Hz range.

For 5.1, I add a pair of KEF 102/2s and a KEF 200C, all limited to 80 Hz. My pre/pro is a Proceed PAV/PDSD combination with Proceed 2 and 3 channel amps.

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
