Thx also recommends it but most of us dont have THX certified speakers. Tom V said if you have a filter in receiver for sub crossover it should be set to off and if you have 120hz crossover for sub in receiver that is where it should be set. The same for sub set crossover to highest level. But the main thing we must remember is we set up our systems to what sounds best to our ears in our rooms.

Below is Tom statement again.

4dB.

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.

In most cases your fronts, center, and rears will crossover at different points. From my understanding you should set your crossover just above where they would drop off. The R's 75hz the C2 60hz so I would go 80 or 100 on those and see how it sounds. The 15's I would set to 80hz. Correct me if I am wrong.

Tom did not say that! He said you should turn up the crossover on the sub to MAX in effect bypassing it. He then said you should use the receiver's crossover and start by setting at 80hz. As for THX certified speakers...are you fricking kidding me? You really need to quit giving out misinformation to people.

Then you need to buy a second PSA Sub. Thanks Tom I will take the commission on that sale.

Keep the subwoofer crossover set to its highest setting(effectively bypass).

Your receiver is already filtering the bass before it goes to your sub.

Here is Tom's post. Please stop trying to muddy the waters. I don't know how much clearer English can be written.

That is 100% correct. Now for the 50,000 dollar question. Where do you set sub to work with those settings? Besides where it sounds good.

Reilly we can go round and round on what's right and what's wrong but the real answer is exactly what you just said. Where it sounds the best to the user's preference is always where it should be set.

Muddy the waters, the subs highest setting is 120hz some even go to 150hz. So where does the 80hz setting come in. You should go to the highest point. 120hz

Here we go again. I don't know anybody that set's their SUBwoofer to 150 hz. Dr. Hsu, who is a very well respected subwoofer designer recommends starting at 80 hz and then set to your preference. Where did you get the info that you should always set the subwoofer to the highest point?

What Tom is saying is you set the sub to the highest point, lets say 150, because the receiver is going to filter it out at 80, 100 or whichever point you choose.

Here is the proper way to do it. You will not find anyone more knowledgeable about this stuff. Then Big Daddy.

If people would read his stickies & apply them this would never happen.

I for one have read & applied them to my HT & couldn't be happier with the way my sound system sounds

That's what I thought Tom was saying also.

PS. The XV15 does go to 150 hz.

Wow. Do you have any clue of what bass management is.

When you set your sub to filter off and your knob on sub to 120hz you are telling your sub to play everything thrown at it. (Do you follow so far its not rocket sceince)

Then when you set your speaker crossover to 80hz you are telling your speaker to play everything down to 80hz and everything below to send to sub. (So that works fine) now the problem is if any of your speakers are set to above 80 hz and your crossover for sub in receiver is set to 80hz where will that signal go. You are telling your sub not to play anything above 80hz by setting the crossover to 80hz. Thats is why you set sub at 120hz in receiver now you are sending everything that your speakers are not playing to the sub to play. Tada.

OK so set the Sub to 150 hz on the subwoofer and then set the crossover in your receiver to the desired 80/100/120. If you feel that there is no localization happening at 120, then you're good to go. If not then drop it to the point where you feel it is ok.

Did I say anything about setting the sub filter in the receiver to "off"? Wow!
