Okay, well I'm learning things every day. I don't know your speakers and I did jump to conclusions, so I was clearly in the wrong.

I thought my friend was wrong in what he said. He said passive crossovers in a speaker will cascade with an AVR. He said the slopes would combine. I thought in order for the slopes to combine the frequency range would have to be the same and I thought the effective range of the active crossover...

The reason I found your example perplexing is that I assumed most speakers did not cross the woofers over so low. I thought it was closer to something like this :

So what crossover frequency do you use?

I guess I am having difficulty accepting that your woofer is low-passed from 120 Hz and down. Most speakers are usually crossed much higher up. The reason why I am complaining is because I am getting CONFLICTING INFORMATION. One place tells me one thing and the next place tells me another else...

For the sake of the discussion consider this issue SETTLED. I understand that setting to Large is not the most efficient method. I have set my speakers to Small.

But I thought few or no speakers had a 120 Hz low-pass on the woofer? What speakers do you have? The whole question was can AVR active crossovers cascade with speaker crossovers. That is what I asked. Either they can or they can't. If most speakers have passive crossovers WELL outside the range...

My understanding of what he said is that electrically, there would be filter interaction between the speaker and the receivers crossover. I don't quite understand how this is possible. If I have a 100 Hz crossover (24 db/low pass and 12 db/high pass) in my AVR and my 2-way bookshelves have a...

My friend is saying : the passive crossovers in the main speakers do not magically disappear ;) the typical passive (having designed and built some myself even) will have a lowpass and a highpass right there on the pcb... many home theatre receiver have highpass of 12db/oct and lowpass of...

Correct me if I'm wrong but the speaker crossovers are usually WELL outside the operating bandwidth of a processor/receivers crossover? So it's also never going to cascade or interact.

I want to apologise for attacking you guys. I didn't mean to lose it like that.

This is supposed to be a place where I can find answers and up until now no one has effectively put this to rest. Just answer the questions already - making me ask the same questions and then repeat myself until I get an answer is not productive. Come to think of it, just forget it. I've wasted...

I take that to mean you can't answer my QUESTIONS.

Apologies for being such a nuisance, I ask too many questions. I want to say thank you to everyone who has contributed. I hope this thread can continue for a little while longer to answer my remaining questions. I just hate it when I don't understand something or when I don't have the answer for...

I mentioned to my friend that if you use both processor LPF and subwoofer LPF that they will cascade. But he tells me that speakers have passive crossovers so any crossover you setup on a receiver or a processor is in effect still/also cascading and that in some cases you will effectively be...

Okay, I read that portion of the manual. He has set all speakers to Large so there is no crossover. So the subwoofer should only be handling LFE. But what is the 40 Hz low-pass then in the advanced menu about??? What does that do if speakers are all set to Large? If you turn your subwoofer LPF...

So now I'm probably more confused than when I started. So if all speakers Large mean no crossover and I've chosen the 40 Hz low-pass on the subwoofer in the subwoofer menu then either that means nothing, it's not actually applying any low pass filter or it IS applying a low pass filter on the...

I read that LFE has a upper limit at 120 Hz. So if you set 80 H for the low-pass on the LFE channel then you ARE chucking away bass in the LFE from 80-120 Hz. Does that not make sense?

Yes but the LFE has information up to 120 Hz. I would imagine if you set the sub low-pass to 70 Hz that you would be throwing information from 70-120 Hz. Wouldn't that be the case?

Sorry, please correct me if I'm wrong but if I select 70 Hz low-pass on the subwoofer, then you are throwing away information in the LFE? The LFE is 120 Hz and down is it not?
