Make sure they match
Jarek, I would try to listen to any immersive channel before you buy too many of them as in my opinion they need to at least roughly match your main speakers in the type of sound they produce.  Here, I've had several hi-end'ish standmounts and bookshelf speakers and they had a very different character to my mains, in that their sound changed as the volume rose (compression) and were generally sluggish and lacked resolution in comparison to Macondo.  Of course there is only so much you can expect from a small loudspeaker with small woofers, so in my case I found that monitors with a compression driver/waveguide had an immediacy more commensurate with Macondo and an 8" woofer could go louder before compressing than a 6".  Plus, I knew that my immersive channels would be in corners and against the walls so front ported is a must should sealed not be possible.  Your requirements will be different to mine, but I would encourage the immersive channels have a similar character to your mains.

As to the $$ poured into my system, it is considerable, but the result of accumulation over time.  I've not kept tabs on it but have operated by concentrating on one facet at a time.  For instance, with my current streaming setup, I demoed and listened and chose and spent much more than initially intended and purchased it all pretty much at once but now have zero compulsion to make any changes as it does everything that I need.  With the Vitavox and other vintage drivers I've kept an eye on what is available and purchased at the opportunity that felt most appropriate.  And of course I have made Macondo/DSET from scratch along with 95% of my bass treatment, furniture, racks and my DHT preamp, LCR Phonostage and various other electronic bits and pieces.  My biggest cost though has been time.  So much learning, experimenting, building, soldering and measuring, but I've loved every minute.

Distorted ULF

A few months ago I met a statement in one on my videos bass channels should not be driven by the same crossoveed signal as a rest of the system.  In my view it is the key. In my current view it needs to be very deliberately "distorted" in order ULF do not destroy your existing low frequency sound. You might discover this time that it is a correct direction to go.



This I do not understand.  Would you care to elaborate?

RI system
Thanks Anthony! What immersive system have you been using? Do your immersive channels process the actual music? I'm going the Yamaha DSP path where according to Romy RI speaker quality doesn't matter much as they produce only auxilary "barking" sounds. Auro is out of my radar due to the small available space.


Cheers,
Jarek

The whole hog
Jarek, I currently do not do RI.  The immersive channels have only been used for audio visual stuff thus far.  I purchased a Lexicon somethinorother to try RI but never got there to take it out of the box.  The Trinnov suits my purposes as I can use it for RI as Romy and Bill currently do it, plus it is good for multichannel music actually mixed for Auro3D/Atmos/DTS (there is more and more of that coming available) and streaming/blu-ray home theatre stuff.

I remember the ambience settings on my old Sony surround system from the '90s and it was often worthwhile to change the ambience effect to suit the music, but it was primitive.  Sounds like Yamaha did it better, but I bet if you want to use your immersive speakers for more than RI then quality will matter.  I am yet to be convinced that the quality of the immersive speakers does not matter for RI, and I would think the basics of having their sonic character at least nominally match the mains is important.

Let's see how it goes...

I think I have a whole video dedicated to it. When you finish your ulf and will be driving from whatever application you will be driving it feels essential is the same your main signal on the passing forever crossover you choose to be. Let's presume that everything works perfectly and you probably calibrate your ulf. Now let's increase your ulf output for one or two decibel. You will feel that it become too much bass. Right? Yes indeed it will be but how would you detect that has become too much bass? Most likely because the Sonic characteristics of your main channels will be compromised but output of your your ulf. This is how all systems are there work.  I do things very differently. My main channels and my ulf do not talk to each other and my ulf penetrates the sound of my channels like hot knife penetrates butter. I might drive my ulf  + 6 or + 10 DB and that character of my main system does not change at all. Is that excessive out put of my ulf introduce only excessive softness of the sound in the room, but does not affect sound itself. In order to accomplish it you need to drive your your ulf not by the signal you drive the rest of the system from on crossover but by slightly different signal, deliberately distorted. The nature of this distortion is a key, they are not bad distortions, I give an example of good cholesterol and bad cholesterol. Finish what you do and if eventually you'll find that you are not happy we will talk.
