Based on my understanding, you need to include 2 other parameters into consideration.
On my setup, I aim for a flat response, thus I did not put any tilt ie 0, thus the starting freq is irrelevant.
The 2 parameters that I’m talking about is the Max correction freq. and HF roll off.
From above they are set to flat and 8kHz.
The resultant effect from the ARC correction is shown below.
While I chose flat, the correction does nothing beyond 8kHz, thus does not unecessarily push the system beyong 8k and just follow the natural response.
My understanding is that playing with the tilt and level is usually to address the output at the higher freq range. One needs to consider the freq response plot against the target curve. By def the Max Corr Freq is 5k and if the correction is needed beyond this limit, it needs to be raised higher. For example in my FL plot, I raised the limit to 8K to address the spike that extend all the way to 10k.
In my setup, the high freq are pretty awesome due to the Be tweeters. However as in-walls, the bass is lacking in punch and rumble. Thus I pushed the room gain by an additional +3dB for the added thump (the original ARC result b4 tweaking is +3dB) thus total +6dB.
I have different target curves for the subs as I try to keep it below the measured response (per advise in the manual).
Overall, I’m quite pleased with the results compared to my experience with the Yamaha… the results are more predictable esp when you can see the freq plots and the many areas to tweak.
Since I made so many changes all at the same time, it is also hard to pin point what each one brought to the table ie
- room treatment (practically a new room)
- new speakers (different layout positions and type/quality)
- new AV processor
- new subs (1 sub to 3 subs)
The good - the many parameters to tweak and the ability to upload new tweaks without running the measurements again and again. The multiple profiles can let you compare different tweaks by just a click of button and swap.
The bad - the manual distance is not ideal and does not cater for sub delays (this one I am still unsure how to address manually). The remote volume - arrgh. The volume constantly blocks the subtitles.
There are more (I can feel it) but off hand I do not have time to list down more systematically and objectively like in a review.
I’ve not tried higher end processors like Lyngdorf or Storm Audio - would love to compare and see what I’m missing (or not). I’ve heard so much about Dirac and that would be nice to evaluate.
