What ATMOS processor (or AVR) do you use, what channels setup and what did it cost (approx)?

Thanks, those are great speakers. Placement wise, I found that the width is not as critical as the depth. It needs some distance from the front wall to get that 3 dimensional soundstage.

Frontal width of front speakers/ Minimum angle of front speakers to MLP

• The frontal width between your front speakers seems not sufficient to have the minimum angle needed for angling VS your MLP based on Dolby specs.
• This affects the overall sound stage + intended frontal sound panning between LCR speakers

These are not your usual conventional but omi-directional (the sound propagates 360 degrees on the horizontal plane). Thus the issue of directivity is a non-issue. Below is the speaker without the grills, as you can see the tweeter, mid and mid-bass driver shape face the full 360 degree. There is a 12" sub-woofer integrated in the ported enclosure.

Surrounds VS MLP placement

• Like what wcseow pointed out, your surrounds placement is not good for 5.x.x wrt your MLP and will affect the intended surround envelop effect.
• Because of your door, I would mount your surrounds near the corners of the rear wall, such that it points diagonally from the rear at an angle to have the intended sound envelop effect for HT.
• Also, do consider moving your MLP fwd slightly besides shifting your surround backwards to achieve the min angle based on Dolby specs. By doing this, your front speakers angle to your MLP will improve too and it will improve frontal sound stage.
• I can’t seem to locate your surrounds in the photo beside your sofa. Are they mounted above?

At the moment, not a lot can be done on the surrounds;
I might look into moving the around, but drilling new holes and relocating the brackets is a major effort especially protecting the existing equipments from dust.

Surrounds are from MK Sound S150, they are tri-pole, so it’s not exactly directional.
The atmos is Elac unit that bounces from the ceiling. I would look into ceiling mount if I decided to relocate the surround.

Wall mounted - a bit too high

LCR timbre matching

• great work in raising the centre high to ear level
• Seems like your centre is different brand. If the timbre and tonality is very different, this affects your HT frontal immersion and LCR panning greatly due to incoherent tonality.
• If your front speakers are much better in specs, and u dont intend to change the centre speaker, suggest u explore phantom centre approach for HT to have a more coherent sound field and sound panning from the front.

You are correct, the center is from Dynaudio Confidence series. My ears are probably not that sensitive to timbre as I find the sound integrates quite ok,… If you refer to my new thread below, I had revised the config,… I brought the center back to the front… not ideal in term of sound placement, however the SQ is much better. I am more willing to accept this compromise. As my screen is not acoustically transparent, it does lose a lot of fidelity when place behind the screen… sound distinctively veil/muffled.

I started a thread to discuss on the room nodes here Room Nodes. There are some plots as well.

Subwoofer

• how low can your front’s go and when does it start rolling off?
• staying on 1 sub seriously will not give u good bass as the serious peaks and nulls caused by the room will affect your sound a lot, both in HT and music.
• as i suggested earlier, get 2 identical subs. Try placing them front middle and rear middle as this is a recommended placement to smoothen the bass response. Play around with placement for the best results…
• Get an Antimode DSP to manage the dual subs.

Are u using your sub for music too? Or do u switch off the sub for music?

The front does goes very low… near 30Hz;
I have moved the sub to the side wall on my left. It is not too boomy and after YPAO, I find it acceptable 95% of the time. I do not use it for music - overkill and integration with the front just not ideal.
