Will have to turn it down for a bit. Then turn it up!

Very nice and subtle.

Dan, don’t want to get too off track here but you mention the room itself, one other thing that was a game changer for me would be power related & specifically the outlet feeding your power distribution. Specifically the top of the line Furutech NCF outlet, had played with other outlets in the past with not much change, this one is a completely different animal. Now I’ve only used the North American version so not sure how the UK compares but if you’re interested at all, check out the Furutech Discussion thread, lots of info there.
Edit: Here’s a link to my first post talking about the outlet swap, if any interest:

Happy to live with what I have in real world system.
500DR has plenty of poke. I drive it hard but it has never given up!

I will have a proper look @daren_p. Thank you 
The room just needed some light absorbing and corners bass trap. The elephant is now eating some trees outside, in the street.

Here is my Artnovion portable absorbers set up.
Playing with placement, but this spot looks and sounds best to me.
I’m toying with the idea of fitting a door from my hallway to lounge room to perhaps make it a bit better.
Don’t know, have emailed the person who does these room treatments and who I got the absorbers from to gauge his thoughts.
It’ll either make minimal difference, worse or yes, go for it he will advise.

Here is the Artnovion recommended project from my photos, detailed room building material, photos and site plan with measurements etc.
No in room measurements taken as I don’t have dealer support in my area.
So I’m not 100% sure if this modeling will be totally accurate (it says so in the site project side notes) vs a REW taken measurement for example.
Of note is the consultant I’ve engaged has also recommended 2x PSI Audio AVAA active bass traps - in addition to the Artnovion Bass Traps that was also this recommended treatment.
Not sure if he’s upselling me the PSI active traps or not, because they aren’t a cheap addition.
Hi @Seacat77,
Looks interesting…….
I can see the treatment is dealing with first reflections on the sidewalls nicely. The recommended treatment of the ceiling is there too in the room model.
Regarding the passive base traps, Artnovion are obviously doing modal room analysis, but what I cannot easily understand if this modelling is done with the knowledge of your speaker placement, or their recommended speaker placement or without reference to speaker placement?
The PSI active traps are probably not being upsold to you, and I understand they are indeed very effective. However, depending on how loud you want to go with your main system, the PSI actives may run out of sound pressure level ‘headroom’.
PS: In any case you can sometimes achieve the same control by adding sub bass(es) behind your listening position and drive them in antiphase. I am not recommending this for your situation as these would get in the way in the kitchen area.
If you find you are willing to spend yet more money, and I note that you have a Chord DAC, you might wish to consider instead a Linn DSM which includes Space Optimisation. This feature allows you to get control of the low frequency modes (below circa 100Hz) in the room and actually QUENCH the resonances.

Can I ask, and perhaps echoing the thoughts of @Edmund-of-Essex, how have you landed on the positioning of the ATCs? Reason I ask is that in rooms that I’ve experienced like this, it often helps to bring 'speakers well forward of the rear wall, quite often a long way, which not only avoids multiple reflections, but can also generate a zone for bass cancellation.

Hi @Seacat77,
Re your consideration of fitting a door. Personally I would make this design decision based on usability and comfort as the lack of the door may actually help with bass resonance dissipation.

If you zoom in on the first modeling picture, I’d say they have done their recommendations with my speakers right up in the corners and almost up against their bass traps. I sent pictures of my speakers as they are set up now, so I’m not sure why they then moved them well into the corners on their model. Perhaps they think it works best with the recommended room treatments they suggest ?
I’m not convinced it’s will sound good at all, bass perhaps will, but it’s against all real advice - even ATC’s own set up advice. Which is to start well away from room corners and adjust from there. Their picture is even closer to the corners than where I am currently.
I landed in this spot because I’m a bit restricted IRT listening chair placement.
I’m going of the rule of thirds and 38% rule. Which is what the modeling they sent me suggests where the bass response is the strongest for the room length. I’m in the middle of the room width, where that room node is the weakest, so I’m not doubling up with both bass nodes at the strongest points - I assumed anyway.
It’s also where the triangle of speakers / listening spot works out to be the same.
It’s the best spot for bass response and dynamics for me. I love my punchy rock music & dynamic bass, so I’ve had to compromise speaker placement for bass response vs better soundstage clarity by moving them well away from the rear wall.
I may have to revisit that choice as I experiment some more to confirm everything.
But it is still a bit off IRT soundstage placement of music playback. But it is a hell of a lot better than where I started from. I also added a 10mm carpet underlay under the rug and that’s helped with room issues as well.
I’ve purchase a computer and got a MiniDSP UMIK-1 delivered today. Just have to get a 4m long RCA>RCA cable to have what I need to run a REW sweep and check everything.
I tried hard to resist that, but I needed a computer anyway as I didn’t have one. So I thought bugger it, I’ll get the measurement mic as well and check my room.
It is a bit jumbled up of what I should have done to start with. Do the REW check first and go from there, but I didn’t want to spend money on a computer and a measurement mic etc, poor decision in the end, as I’m so very curious now to compare the Artnovion model vs what the REW sweep comes up with.
Hi @Seacat77,
I few of us the forum (@HappyListener) are working with you ‘at pace’ as people say!
Firstly, although Artnovion possibly (although I am not convinced) do show the speakers in the corners (and it will simplify their modelling assumptions), as you have correctly identified this is NOT the best place for them necessarily in your circumstances.
For your information, I once had some professional come round to tune the bass response in my room. Their approach was to keep moving the speakers into the corners until the sound was sufficiently ‘tight’ in the bass. Well it was a small improvement to my ears and completely destroyed the depth of soundstage. So I went back to the original positions of the loudspeakers, which you have indicted you are using in the ‘rule of thumb’ description in your posting.
PS: I can see your speakers in the room visualisation for how ‘lovely’ the room will look with their treatments, however I do not see the speakers in the modal analysis tool visualisation.
Yes I noticed that too, not sure why they didn’t add them to the modeling as well.
It would assist me greatly to see what speaker placement they suggest.
I forgot to add, I sent them my system list - everything- from my power cables to my ATC speakers and everything in between. So I assumed they would have factored those into the modeling scenario, well the speakers at least.
I think you need to open a new thread on this, as this is hijacking Dan’s thread a bit too much IMHO.
