    Some boost under 20 would do well enough for this one. JSS

    Very interesting observations. How does the FL/FR/BL config do higher in frequency velocity/phase/FR wise? What size driver/sensor do you use for velocity measurements? I need to actually do these measurements at some point. JSS

    Make sure you put a finish on the cab before you install the driver. I have had cabs that went without finish for 3 years, b/c after the driver goes in, it is so easy to just listen to it. JSS

    Good to see you here! Interesting... Can you run the same audio through Audacity's Clip Fix plugin and see if you get similar results? I think Clip Fix runs a bezier fit, this looks similar. JSS

    Mr Allen at HPS4000 has been echoing your sentiments for some time: http://www.hps4000.com/pages/articles_page_.html Even though he considers <27Hz not part of the audible spectrum (he is not wrong depending on frame of reference, hence his choice on subwoofer low corner), he has some solid ideas in those articles, and addresses many of the things we complain about here.

    Commercial cinemas, when designed, implemented, and maintained properly provide a great low frequency experience, similar to a well done live concert. The caveat is that the experience does not extend much lower than 25-30Hz. Most impact/slam is between 40-100Hz and even higher in frequency. We are freaks here that can monitor and playback the lowest frequencies, that are often taken out of a mix that is CREATED and is meant to be played on a cinema system (25-30Hz vented, high sensitivity subwoofers). While mixing stages have existed in the past that could monitor into the low teens Hz-wise, most cannot monitor below the high-20s. We sometimes are surprised by mixes that do not exclude the content below 30Hz, as those mixes are a significantly different experience in a properly equipped home theatre. Your friends may simply be used to a certain frequency and level of low frequency experience, and call that 'good'. The EQ mixing described is in the Bass EQ for movies thread on this forum. JSS

    The Incredible Hulk is still the track I compare all others to. A close second is the Star Trek reboot, War of the Worlds, and all of the 5-Star films on the first page of the thread. For lots of 20Hz and below energy, Battle:LA is hard to beat as well. JSS

    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
  20. maxmercy
    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
  21. maxmercy
    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
  22. maxmercy
    Going from 1 to 4 units, where are they located in Room2, and how does the placement affect SFI/Velocity? JSS
  23. maxmercy
    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
  24. maxmercy
    Agreed. 9 is terrific, it merits is 5-star rating JSS
  25. maxmercy
    That is a significant difference streaming vs BD. Have you listened to each for differences? JSS
