So if you set sides to 100hz and Sub to 80hz any signal between 80hz to 100hz being sent to your sides are lost. I am not twisting your arm to put your sub on 120hz but just stating what happens in bass management.

Why would anyone set their subs to 80 and their mains to 100? I have the high pass for my mains set to 80 and the low pass for my subs set to 80. As Tom explained the crossovers aren't a brick wall as there is no perfect crossover to completely filter out the above or below frequencies. You will have an overlap and won't miss any freqs in the spectrum.

This is one of the reports that states what I said.

I would not rely on About.com for information on setting up a home theater. You will get much better information on this or other similar forums. There are sticky's in this forum that will tell you all you need to know.

I am not quite sure what you were trying to say about using the 'y' cable. But in any event, if your other speakers can handle frequencies down to 80hz I would use that setting. If they can't then you can try to raise it. When I have raised my settings to 100 or above I was easily able to hear where the sub was located.

Nice to see Tom keeping an eye on us.. :P Love my sub by the way Tom!
What if you put all your speakers at 80 and sub at 80?

You dont use your sides, rears, wides or front highs when you watch movies and you set all your speakers to 80hz or below. Not once did I say fronts So you just took it as you wanted to, to fit your need to argue? And disagree.

Exactly Raynist! You don't want the sub to be localized by raising it too high.

I too don't understand what a y cable has to do with. All that does is raise the voltage of the signal from your receiver to your sub's onboard amp.

Maybe if you explain yourself better I would know what in the world you are talking about? I think I don't quite understand what you mean.

I was talking about the statement that was bolded from the report I pasted the link for also. Every one just got pissed at me and paid no mind to one of the reports I got info from. I dont know if report was wrong or right.

But a I think it is time to move on.

I think you need to realize that the five surround speakers have a high pass crossover and the sub has a low pass filter.

What dont you understand about below statement.

Now if you are running bass management and put your sides, rears, wides or front highs above 80hz where does the bass go if your crossover is set to 80hz on sub? So if you set sides to 100hz and Sub to 80hz any signal between 80hz to 100hz being sent to your sides are lost.

I took Tom's advice and moved my crossover down to 80Hz on the sub and adjusted the receiver crossover to 80Hz also.

As a side benefit, all a powered subwoofer needs is a single cable connection from a home theater receiver or surround sound preamp/processor line output (also referred to as a subwoofer preamp output). This arrangement takes a lot of the power load away from a receiver and allows the receiver's own amplifiers to power the mid-range and tweeter speakers more easily.

This quote is correct but I think you just interpreted it incorrectly. If you use the sub out/LFE or whatever your receiver calls it, and then set the crossover on your receiver to filter out bass to the other speakers it will free up power to drive frequencies above the cutoff. You can take the sub/LFE signal coming out if the receiver and split it any number if times (I have it split 3 times to power 4 subs in one application) without affecting how the subwoofer is powered. Some people like to split the sub signal with a Y adapter to send a signal to the left and right inputs on a sub. I did this to a sub i once had that was not coming on when the volume was set at a low level.

I'm not disputing that the freqs between 80 and 100 hz could be less recognizable under that scenario. Setting all crossover points to 80 hz within your receiver isn't necessarily a bad thing though. It's all subjective though so set your stuff however you like it.

I sorry they said nothing in that statement about crossover in receiver. So you just made a assumption that is what he means. I am sorry I did not come to the same assumption as you. But that is what makes these forums good. You learn new things every day.

I also split my subs with a Y adapter but from my reciever. But never have at the back of the sub. After reading many post and reports it seams you gain about 3 Dbls at Sub using the Y adapter in the subs lfe & right input. Ands lots of folks say it is a waist of time. But to go off topic I run all my speakers Bi-Wired and the same thing some folks think this is a waist of time also and some swear by it.

The y adapter doesn't gain you 3 dbs per say, it essentially makes the volume on the sub more sensitive. The sub will be louder at the same given level but it will still run out of steam at the same approximate db level. People use the y adapter often to make their subs wake up more quickly more than anything from what I've read. Some subs have gain levels that aren't very sensitive.

Yes I am learning that now. The big thing is understanding bass management and what it does. When I use 60HZ on my fronts it takes longer for my subs to wake in music and movies. If I use 80Hz on my fronts the sub is getting more bass that my fronts are not playing so they dont really go to sleep. So a lot has to do with how your crossover is set to dictate how much bass is going to sub. I am just quoting what bass management is saying but we all need to listen to our system at what sounds best to our ears.

Below is the stickey From Big Daddy on Bass Management. It is excellent.

I'm watching xmen first class right now and man the lfe track is good! I can't believe I waited this long to let it rip on this movie. Your power sound audio subs will love it!

Below is Toms Advice where did he say to set to 80Hz

2)The LFE channel itself. I've seen some receiver's that allow the user to select a crossover point for this channel. (they usually offer 80/100/120hz). Since the LFE channel itself is specced 3-120hz I don't see any viable reason to "filter" it so I would set this option to OFF/120hz if you have it available.

Tom is saying to set filter Off and to 120Hz on sub. Dont mean to be a Blank Head. Fill in the blank.

You need to roll Transformers and Tron legacy. The A team would sound good too a lot of explosions in that movie.

The forth movie in the Underworld Series has some of the best all around sound I have heard in a Blu-Ray & Kate Beckinsale does not hurt the movie one bit

The paragraph above what you quoted and he didn't advise he informed me of more attenuation at a lower setting. I made the choice...
