  1. Agreed. We essentially just got a flash and low boom/rumble. Not the ST warp-boom blastwave I was expecting. One of the best movies I have seen. JSS
  2. I may have to check this one out. BTW - I got most of the links fixed from the first post. Still need to fix the 3-3.75 star films' links, will hopefully get to it soon. If anyone notices a missing graph on a post, let me know. We lost all of bosso's scenecaps at some point, unfortunately. If anyone has any film requests for measurement, let me know. JSS
  3. Hey Ricci! I have not really been watching films as often as I used to the last few years, partly in fact because I have yet to rebuild the HT since I moved. I have a decently capable temporary HT outfitted with crowson transducers so I can monitor the Infrasonics, and the plan is to be reviewing a few films every month. If anyone has any suggestions for movies of the last few years that you would like evaluated, post the requests in this thread, I'll try to get everything updated so the thread works as it used to. Also now that Mandalorian is out on BluRay, I may get around to measuring it, as some of the episodes sounded like they may have had some great sound design. JSS
  4. Let us know what you think of the bass in Transformers - Rise of the Beasts
  5. 4.5 Star Film links are now correct in first post. Vote on Oppenheimer if you get the chance. JSS
  6. Let us know what you think about the bass in Oppenheimer
  7. The 4.75 Star Films now have proper links, some images got lost on the PvAs of the 4.5 Star films that I am working on correcting. JSS
  8. Slowly I will start fixing the links in the first post. All the 5-Star films have correct links now. JSS
  9. So TDKR was kind of a mess, fidelity-wise. Lots of clipped tops make for a harsh soundtrack. Watching the movies back-to-back and with a surround system (down-mixing to 2.1 unless your AVR is doing it from an LPCM source will introduce dynamic compression by your AVR) is enlightening. I think TDK is one of the best soundtracks around, and TDKR could have been, if someone didn't just turn the gain up until every loud effect clipped. Another reason TDKR got such bad reviews here is this: This is the entire PvA for TDKR. But if you isolate the first 10 minutes: You can see it is a full bandwidth presentation with effects into the single digits. The rest of the film, however, is different: With a significant rolloff under 30Hz. The difference was easily heard and felt in a system that can reproduce under 20Hz. It is as if the ultra low bass knob was simply turned down. If you remember when TDKR was initially in theaters, a special 'Prologue' was released in IMAX theaters 6 months before the movie was released. It is my theory that this prologue was mixed independently and that mix was kept for the final film, and the rest of the film got highpassed when mixed. Unfortunately ALL of it is clipped. One of the worst cases of clipping in a movie I have seen, and heard. The first time I became aware of clipping was in Tron:Legacy, when I saw the BluRay and it was definitely different compared to the theater presentation. The effects dug deeper, but the sound was clipped in many places, confirmed by looking at the waveforms. JSS
  10. You can see here that TDK only clips in one channel, at only two points in the movie: This is the entire movie, all channels, L/R/C/LFE/SL/SR in order 1-6. Just after the one hour mark, the center channel clips in one place (marked in red), and once at the end. TDKR, however, is a different story: As you can see, the screen channels clip nearly throughout the film, followed by the surrounds, then the LFE. It is an utter disaster, and the soundtrack is very loud because of it (one of the loudest I have measured). JSS
  11. "(notable the scene involving the underground/tunnel money transport chase)" Are you talking about TDK or TDKR? I can graph the opening vs rest of film soon, I'll post it up. I thought I had in the past, but didn't. JSS
  12. Christopher Nolan definitely has the 'wall of bass' sound design pretty well worked out. Ever since The Dark Knight Rises, he has used the technique a lot, especially for Interstellar and Oppenheimer, but he does clip the sound at times, sometimes as an effect. The only thing that was strange about The Dark Knight Rises was the fact that the opening has a completely different and unclipped sound signature compared to the rest of the film. With your LF setup, Nolan and Ridley Scott films will be very impressive. That is a lot of SPL capability there. JSS
  13. MK, I have had very different experiences with streaming. Sometimes it just sounds 'off'. I have never measured them, though. BluRay (2k or 4k) is still the best presentation available, IMO. JSS
  14. Lots of variables there. If I were you, I would sim many options, including the room. Use WinISD or a similar enclosure program and RoomEQ Wizard's Room Sim. 100dB capability at 20Hz (at the main listening position) means you will be playing movies at around -20dB on your receiver (if calibrated to cinema reference). For many people, that is enough to satisfy them. Clean 100dB at 20Hz is not easy on a budget. With a low budget and limited power (100W), sealed enclosures will limit SPL and extend a bit further down low (using power), vented enclosures will limit extension by essentially 'boosting' SPL above tuning. If you have woodworking experience, making a tapped horn/folded horn sub will get you a lot more SPL for a limited power/budget scenario. There are plans out there for these enclosures. Also multiple subwoofers can help tame room modes. Nearly every small room low frequency setup benefits from EQ capability, but you have it with the Audyssey built into your receiver. No need for lots of DSP if your receiver already has it. I would also recommend buying a used/refurbished sealed/ported sub with an included plate amp which may let you know what will be 'enough' for you and you can then plan accordingly for upgrades. One or two 10-15" subs should be enough to get you started, and if you are lucky, get a little room gain. Look at ebay. JSS
  15. Transformers: Rise of the Beasts - Dolby ATMOS (7.1 DTHD bed graphed) Level - 3 Stars (108.63dB composite) Extension - 3 Stars (19Hz) Dynamics - 5 Stars (27.53dB) Execution - OK. Not great, not terrible, incorporates several effects from prior films, but does not distinguish itself much. Let us know what you think. JSS
  16. Oppenheimer: Level - 4 Stars (111.3dB composite) Extension - 5 Stars (8Hz) Dynamics - 5 Stars (28.9dB) Execution - 3 Stars by poll. Very powerful sound, very reminiscent of the great rumbles in other Christopher Nolan films, but at the expense of clipping in every channel except the surrounds in both the 4k and 2k tracks, which appear identical. Overall - 4.25 Stars JSS
  17. I see what you mean, I was only talking about ELC and how it relates to my experiences with both sinewaves and real content, in a "high fidelity" system. I agree, linearity is a huge deal. Listening/feeling experiences with an old system of mine with large peaks at 30 and 60Hz were significantly different from a later system that had much better control of the room via acoustic treatment, mode cancellation via multiple subs, proper headroom and proper seat placement with some EQ thrown in to tame the largest leftover resonances...that system was very good. What is strange is that in some movie scenes, the tactile effect of the old, peaky system was far more present. Complex subject indeed. JSS
  18. The article listed on that page: http://www.filmaker.com/papers/RM-WhtPpr_Subwoofer Camp.pdf Brings up something that few do, except MonteKay: http://www.mfk-projects.com/Home_Theatre/theatre_woofer.html It is a very important point. Due to the way our ears 'hear', a near infrasonic sound must be played back more cleanly than a midrange sound in order not to have upper harmonics 'color' it due to equal loudness curves. I did several experiments with my first decently low distortion subwoofer system and it is enlightening seeing total harmonic distortions of just above 1% significantly coloring a pure sinewave tone upon playback at louder levels. Of course, at loud enough levels, things rattling in the room 'color' the sound far more, until you start fearing for the structure. Clean reproduction of bass is very difficult. If you can play a 20Hz tone and with your eyes closed you can point to where the subwoofer is in the room, it is anything but a clean reproduction. JSS
  19. I have this film, and this it how it graphs. From about 1:33 to about 1:39, there is a strong 20Hz effect, you can see it in the average and peak graphs. At one point it is encoded as hot as 108-109dB If played back at 'Reference Level'. With a real low distortion playback system, it would lend an ambience to a scene that many would find disconcerting. Low distortion 20Hz playback is rare to achieve. JSS
  20. Are the t.amp amplifiers readily available in the US? JSS
