Thank you.
I have talked and worked with Edgar many times. How he manages to do all that he does is beyond me.
He is a human dynamo. Nobody I know talks as fast as he does!

I have the Bacch4Mac with the Babyface Pro + and room correction output through Roon.
Is there anything more to be dome to activate the room correction other than to run it with the microphones in your ear in the listening position?
If I understand you correctly, a point source box subwoofer is just fine to use with the Poporis so long as  the subwoofer and Popori's output frequencies don't overlap.

Yes, Edgar is quite something else.  You will need to be sure the settings in the ORC section are correct for what you want to do.  Very often the default setting are fine, but for the Popori by itself, set the low correction limit to 40Hz.  Also, allow 4-6 dB of boost.  When mating a sub have its gain set high.  ORC will trim it back.  Also have ORC set to the low limit instead of that 40Hz.

If you have the ability not to overlap by using two separate  crossover frequencies, I have found that to be best.

What I have found is when the main speaker radiates bass in a figure 8 pattern, like here, then you really really want to have the sub match that pattern.  Box subs stick out like a sore thumb because they radiate like a pulsing sphere.  Makes perfect integration almost impossible.

Has not been my experience and I cross over well above 100 hz, but I may not be as fussy as you with all of your show experience.  That's not a dig, but an honest assessment.
The sub used is probably more important than the pattern, and also the implementation would be critical. I would also say it has to be acoustic suspension, or sealed, to blend in.

Here is the link to my Popori WR3 install and set-up that has just been released'

There are two things that I did not go into detail about in the video that I should have at least mentioned.  The first is that the differences in frequency responses were probably also influenced by the construction differences of the room itself.  The second is when it came to fully understanding the timing issues.  Because of the differences between right and let channels in frequency response, the corrective mix of settings used is different for each channel.

How do the Popori's sound compared to your previous VMPS speakers?

[Housteau]

The V60s are really fine speakers.  That is why I had them for so long.  But, they are also complex with a lot of different drivers and parts.  The Popori are very simple having a single driver and no crossover.  That simplicity comes through as having more resolution and transparency.  A single driver reproducing the entire frequency range just can't be beat.

Thanks for the great video Dave. Fun to finally have video of your listening space after all these years, maybe 20, ha.

My question is, did the woofer towers rolling off at 12 db/octave from 38 hz fill in all of the W3 roll off starting from 200 hz, or was e.q. added by the Baach or active crossover?

I was surprised that removing the foam pads brightened the sound as I thought their purpose was to reduce bass output to accommodate closer rear wall positioning. I can understand the foam reducing the highs though.

I had some RM30s and liked the way they imaged and looked. Thing was the bass was a bit wooly, but far worse was the speaker sounded hard. Could be old capacitors, etc, but I did not have the time or desire to mess with it. Otherwise, they could have been a long time companion.

The BACCH system has a module called ORC, or Optimal Room Correction.  Towards the beginning of the video when I tried the first crossover point at 50 Hz, I showed that chart, then reflected back to the WR3s chart on their own.  In jumping between charts, you can see how ORC corrected the frequency response except for those dips in the left channel.  That was eventually fixed by the timing corrections explained at the end of the video, which the 12 dB slope was a part of.  That Xilica active control system has the ability to make very fine adjustment in many areas.  I did use it sparingly to help correct different areas as well.

I have read that about the foam pieces as well and to be honest the manual seems a bit counter intuitive about that.  It could be that they reduce a large band of frequencies, but with them further out into the room it is just the highs that get noticed.  Also, by reducing bass output the highs would seem more prevalent.
