Are you up early or late?

I thought that too initially but apparently you wont have too go that high unless your speakers are really small and unable too handle those mids.

Going a bit lower is best i gather because you wont hear stuff like male voices coming from the subwoofers. Above 80hz is starting too get localized and you might notice the sounds going back and forth between the speakers and the sub.

But this is just something i've read someone say on the web. Trust your own ears mate, 120hz sub lfe is a popular choice.

Although you may be getting the flattest overall frequency response, from what I understand, if you set your LFE any lower than 120hz, the discrete .1 information above that lower point is thrown away, and not bass managed and redirected like your speaker crossovers do.

From Chris Kyriakakis: "It's a filter that is applied to the content of the separate LFE track found in 5.1 content. That content is authored up to 120 Hz and so the only correct setting is 120 Hz."

From Big Daddy: "What is LFE (Low Frequency Effects)?
The LFE (.1) provides a dedicated channel for the low bass that is used in theaters to add impact to the movies. The LFE signal is band-limited to frequencies below 120 Hz.

The LFE channel is an independent channel and has no effect on the other speakers. The information that is in the LFE channel extends up to 120Hz regardless of whether you have bookshelf speakers or full-range super tower speakers. It is important to distinguish between the LFE channel and what goes to a subwoofer. The LFE is a production channel, whereas the subwoofer is a playback channel."

Cool thanks for this. Yes you might loose some of the information if the mixer included lfe material there. So it's either this or live with the slightly localized sound hehe.

Another issue could be ones subs aren't able too provide clean output at >80hz.

Right now im just playing around with crossovers and panel placement. No harm in that.

If you want all of the material keep your lpf of lfe at 120hz Joe. Please bare with me as im playing russian roulette with my ears.

From what I've read, there isn't usually much, if any info between 80hz~120hz in the discrete LFE channel most of the time anyway. I have played around with it a bit, and it does seem to clean/tighten things up a little by setting it down to 80hz, but technically you could be losing some information by setting it lower. Hey, it's your setup. Do whatever sounds best and makes you happiest.

One thing that I don't understand, is that if it should always be set to 120hz, then why even make it an option to adjust it? I guess for 2.0 sound recordings, since there isn't a discrete LFE channel, you might want to adjust for that.

By the way, nice smiley.

You know, I've never seen that movie. It seems like something I would really like though. I'd like to check it out sometime.

I just read that whole thing, and it was very informative. There are several things discussed in there that I have adhered to, and a few that are less than ideal in my setup.

I will eventually. I can't even think about buying any BD's right now though. I'm trying my best to not have to sell anymore of the few I have left.

Sell the car and run too work. You'll save gas money and get better blood pressure at the same time.

Hi Joe, I remember you saying the first place you were turn down for a job was a chicken place. Don't remember if you mention what type of food is at the place you are training for.
