Nearfield subs done right can change an HT experience. It is VERY easy to overdo it with them, though. JSS

I do not have overhead channels, maybe someone who runs ATMOS at home can chime in. My surrounds are mounted high, so an effect panning between two surround speakers sounds like it is 'overhead', like the mailroom scene in Fantastic Beasts. JSS

Star Wars: The Last Jedi Pre/Post: Significant improvement, all the effects that should have more infrasonics gain some, especially effects that are close to the viewer/camera. Lots of infrasonic noise in the track, so the highpasses are necessary to avoid a DC offset to the track, since we boost those infrasonics so much. The track with the below changes played back at +4dBRef (equivalent reference level) has a Dynamics score of 31.26dB, and no effect is greater than 121dB, no extended effect greater than 114dB. Capable systems will like this correction. Do not apply this correction on top of a 'house curve'. At most, a smooth 10dB rise from 20kHz to 20Hz is all that is needed. Correction was applied to the 7.1 channel bed of the ATMOS track, the DTS track is similar, but I did not test this correction on it. LFE: Gain -4dB Low Shelf 14Hz, Slope 1, +5dB Low Shelf 15Hz, Slope 1, +5dB Low Shelf 16Hz, Slope 1, +5dB Low Shelf 17Hz, Slope 1, +5dB PEQ 20Hz BW 1 octave, +3dB PEQ 65Hz BW 0.75 octave, +1.25dB Highpass 6dB/octave 3Hz LCR: Gain -4dB Low Shelf 20Hz Slope 1, +6dB (3 filters for 18dB total) Highpass 6dB/octave 3Hz Surrounds: Gain -4dB Low Shelf 40Hz Slope 1, +6dB (6 filters for 36dB total) Low Shelf 45Hz Slope 0.5, +6dB (2 filters for 12dB total) Highpass 6dB/octave 10Hz JSS

Star Wars: The Last Jedi (Dolby ATMOS - 7.1 channel bed measured) Level - 1 Star (104.91dB composite) Extension - 3 Stars (17Hz) Dynamics - 5 Stars (29.19dB) Execution - TBD Overall - TBD Notes - obviously mixed below theatrical reference, with a dynamic, unclipped presentation. Playback at -4 to 0dBRef for best results. Solid soundtrack. Gets even better with BEQ. JSS

Will post up later today. In short, it is a quieter, but very dynamic track that doesn't clip. JSS

LCRS were shelved away at significantly different rates, similar L/R/S, and then C was very different with more ULF. BigMarket and escape from same was very good, as was the initial damaged ship flying over the pearls. Significant content there. Decent film, but like Dredd, not sure there is enough traction for a sequel. JSS

Valerian and the City of 1000 Planets: Good improvement on this one, esp the Intruder scenes. Tough correction, lots more infra in C than in LRS. LFE Gain -7dB Low Shelf 17Hz, S=2.5, +3dB Low Shelf 18Hz, S=2.5, +3dB Low Shelf 19Hz, S=2.5, +3dB Low Shelf 20Hz, S=2.5, +3dB Low Shelf 34Hz, S=0.5, +0.75dB Low Shelf 36Hz, S=0.5, +0.75dB Low Shelf 38Hz, S=0.5, +0.75dB Low Shelf 40Hz, S=0.5, +0.75dB Center Gain -7dB Low Shelf 30Hz, S=2.5, +3.75dB (4 filters for total of 15dB) Low Shelf 60Hz, S=0.5, +3dB LRS Gain -7dB Low Shelf 25Hz, S= 2.5, +6dB Low Shelf 26Hz, S=2.5, +6dB Low Shelf 27Hz, S=2.5, +6dB Low Shelf 28Hz, S=2.5, +6dB Low Shelf 50Hz, S=0.5, +1dB Low Shelf 52Hz, S=0.5, +1dB Low Shelf 54Hz, S=0.5, +1dB Low Shelf 56Hz, S=0.5, +1dB Low Shelf 70Hz, S=0.5, +1dB JSS

Thor:Ragnarok This one improves, but it is not a night/day difference like Spider-Man above. The arena battle's improvement is significant, but there are a few high-energy infrasonic hits at unexpected times. Not the best BEQ, but definitely improved. This correction is applied to the DTS-HDMA track on the BD, not the ATMOS track on the UHD. The ATMOS track is dynamically compressed for the first hour, and is an inferior soundtrack. LFE Gain -7dB Low Shelf 15Hz, Slope of 1, +6dB Low Shelf 16Hz, Slope of 1, +6dB Low Shelf, 17Hz, Slope of 1, +6dB Low Shelf, 18Hz, Slope of 1, +2dB LCR Gain -7dB Low Shelf, 35Hz, Slope of 2.75, +5dB (3 filters for a total of 15dB) Low Shelf, 70Hz, Slope of 0.75, +3dB Surrounds Gain -7dB Low Shelf 25Hz, Slope of 1, +6dB Low Shelf, 26Hz, Slope of 1, +6dB Low Shelf, 27Hz, Slope of 1, +6dB Low Shelf, 28Hz, Slope of 1, +6dB Low Shelf, 20Hz, Slope of 0.5, +4dB JSS

Spider-Man:Homecoming BEQ This one really improves. The correction is applied to the ATMOS track's 7.1 bed. The 5.1 track is different. Correction as follows: LFE Gain -7dB Low Shelf 15Hz, Slope of 1 (Q of 0.707), Gain +4dB - 4 filters, total gain 16dB LCRS Gain -7dB Low Shelf 15Hz, Slope of 0.5 (Q of 0.5) - 2 filters, total gain 10dB Nearly every effect that should have more infrasonic impact improves JSS

Good to know. Have you every heard an SBA/DBA? JSS

Kvalsvoll, With all 4 configurations, (1,2,4), for equal SPL with each, which configuration had the greatest perceived impact? JSS

How does the relative impact at a certain SPL change when velocity components are also coming in from the sides and from above/below in the smaller configs? JSS

Interesting findings, form factor for those subs is good. Do you think there is a correlation to room mode cancellation and velocity measurements? The front wall looks like it has absorption with a 1D slat diffuser in front, is that new? JSS

Going from 1 to 4 units, where are they located in Room2, and how does the placement affect SFI/Velocity? JSS

Justice League did the Avengers filter....too bad. Haven't really gotten into the DC expanded universe. MrEdge, any idea where in the film that ULF peak is? It is significant.... JSS

Agreed. 9 is terrific, it merits is 5-star rating JSS

That is a significant difference streaming vs BD. Have you listened to each for differences? JSS

Wow, that looks like a track AFTER BEQ. Hope it doesn't clip everywhere....should have an incredible Dynamics score. Thanks MrEdge! JSS

BH6 was inconsistent, with some effects having very little impact, and others great impact and heft. It's as if there were many sound designers, and some used highpass or shelves when creating the effects, and others didn't. JSS

That is a significant change....have you listened to the new track? JSS

Wow....EVERY effect must have 20-30Hz.....quite the impressive 70 to 30Hz slope... Think it clips? JSS

Audyssey's Dynamic EQ may do more that that... Best news I have heard in a while; possibly confirmed by my experience with Star Wars:The Last Jedi, where I guessed the level of playback on an opening night showing within 0.5 'units' on the Dolby Box (confirmed by the theater's general manager). Good to know the theatrical/home mixes aren't substantially different at Technicolor (still where FilmMixer is at?). JSS

I thought WW was well done but prob could use a little BEQ, but not much. It was very similar to Man of Steel in the LFE channel, IIRC. I'll look at it when I get a chance. Loved the film. Closest the DC Universe has come to approaching Marvel quality (Batman Begins and The Dark Knight excepted). Reminded me a lot of Thor, with the 'fish out of water' plotline. JSS

What window did you use? It seems that to get a 'real' picture of what is happening with a PvA for this type of correction, we would need a reference 'line' placed on the avg graph or tilt the average graph counter-clockwise to see deviations from 'level' (a downward-sloping target curve). Main thing I see here are the broad 'boosts' centered around 1kHz and 8kHz. WaveShop is probably a better app to use for these Spectrums, and very fast, too. Interested to see the 'after', and if you can, do a pre-post image shifting the colors for the post. JSS
