Maybe in theory but in a real listening room you can easily locate a subwoofer that is crossed at 80Hz.

Using speaker terminals to connect extra subs could work (since Dirac probably could EQ it), but you need to add passive high bass filter for that speaker. Otherwise it will badly overload while the parallel connected subwoofer still plays fine. Better option is to connect couple smaller subs...

Not sure why you would use 100Hz? I use all speakers up to 150Hz and both subs (front/rear) 100Hz. And that 100Hz sub limit is only because LFE, for music I would use 150Hz also for subs. I will experiment more with this and change rear sub (sub2) to 250Hz lowpass and 150Hz ART support. When...

It will, that 100Hz lowpass filter is on my Crown XLS amps, not ART or AVP/AVR. I tested with higher filter values but 100Hz seems to be perfect for LFE (removing localisation of higher notes coming thru sub1). Of course I could use it only for sub1, but there are capable speakers near sub2...

Here is LFE channel REW measurements with ART correction, 7.2.6 setup. First picture has all speakers and two subs active. Next one has only subwoofer1 active. And the last picture has subwoofer1 turned off and sub2 and all speakers active. Both subs have 100Hz 24dB/oct lowpass filtering active...

ART also doesn't seem to EQ subwoofers like regular Dirac does, it uses other speakers' support to do that. I'll have experiment what happens when PEQ is used before running ART. For example, my second sub has pretty bad drop around 23Hz and regular Dirac corrects it. But ART doesn't use EQ for...

How is that done? Since ART does bass management and splitting/filtering bass and LFE to different subs how can you clone LFE to other subs before ART? There shouldn't be subs before ART.

First sub plays LFE + bass managed signals from other channels + ART cancellation signals for different channels. Other subs play support for LFE channel + bass managed signals + ART cancellation signals for different channels. (default settings, you can remove/add/change support etc.) What...

What is LFE in your opinion? Isn't LFE just one of Dolby/DTS channels? So I don't understand what you are talking about.

But they send bass managed low frequency signals to all subwoofers and add ART correction signal on top of that. What is there to reinvent if they did the same for LFE?

Full LFE signal goes only to first subwoofer.

Maybe you don't fully understand how ART works and what it does with support speakers/subs? It's not about going below 20Hz (and ART doesn't even work below 20Hz).

No matter how good L/R speakers are, they will still benefit from support speakers and/or subwoofers.

I use ART (also) with 2 just speakers and it does work much better than regular Dirac. I think I earlier posted here REW measurements. But of course it's nowhere near as good as with multiple ART cancellation speakers. Listening position (for best ART effect) is more limited. And some room modes...
