  5. The Low Frequency Content Thread (films, games, music, etc)

    in Bass Content

    Posted

    According to the statistics released from a recent CinemaCon, these new technologies are not helping to sell tickets. 4k double projection, laser projection, HDR, Atmos surround sound, tactile transducers, 4-D/interactive, D-box...nothing.

     

    What people like are newer style, big comfortable reclining chairs and a really big screen. Better/improved bass is never even a thought.

     

     

    I think what you're basically trying to say is that the great unwashed are uninformed and uninterested ;) lol, but sadly the latter means the former will likely never change because people are too busy staring at their ****ing smartphones to see what pointless crap their 1000+ 'friends' have posted online in the three minutes since they last checked their phone...

     

    I don't even look forward to going to the cinema now, I rarely come out thinking 'I really enjoyed that' because the sound is usually so gratingly goddam awful, sigh.  I am hopeful that a 'boutique' cinema I've found might be better, but I have a feeling it will just have sofas with no back support, scatter cushions, an 'artsy' interior and just the same crap quality sound, despite probably being double the price of an already expensive standard ticket at Cineworld or Odeon...

     

     

     

    Man, I'm feeling positive today :lol: lol

  6. The Low Frequency Content Thread (films, games, music, etc)

    It should not require a shelf or high-pass to the soundtrack, but we often see it, likely because Infrasonic events eat up a lot of headroom on a track.   

     

    But does it??

     

    Assuming I'm not going insane and mis-remembering, the graphs for the failure that was The Hobbit vs The Hobbit Extended Edition were interesting - IIRC they just added new scenes with new (30Hz filtered) audio and didn't touch the existing (40Hz filtered?) audio, so the bass (if you can call it that) came in with the new material and disappeared again when it finished.  When the original and extended versions were graphed onto the same graph, the additional extension was obvious but the upper end was literally virtually identical, even taking into account whole new scenes that would have changed the graphs somewhat.

     

    I'm just not convinced it is a valid justification from the mixing people!  unless, of course, they are dealing with Nolan and any other similar directors who personally crank everything up to 11 and are touching/flat-topping to 0dB on the levels on the disc.

    There is very little to no interest in "that world" for more bass extension beyond 20-30hz.

     

     

    What someone needs to do is arrange a visit to any one of the ultra-low-end-monster systems on here for some industry bods in high places, the ones who spec the rooms and mix the mixes and sign off the audio - I can't believe anyone with a brain and a sense of wanting to get the best from their work would walk away from a Bosso system or our friend with eight HS24s and unhappy neighbours ;):D saying "nope, I felt no difference, there's no point".

     

    How much does it cost to spec a mixing room these days?

     

    And how much would the monster 8x24 system cost to recreate?  Say $8k - $12k for drivers, and how much would amps and enclosures and cabling be?

     

    Given the likely price of the 'pro' stuff being used, one does wonder if a drag-and-drop, plug'n'play Ricci-special quad-19 setup could be offered up for trial.  Just imagine - how awesome would that be if Ricci and DB forum single-handedly changed the mixing rooms for the better ;):D

    I'm using two of these: https://www.amazon.com/Noctua-NF-F12-PWM-Cooling-Fan/dp/B00650P2ZC/ref=sr_1_1?ie=UTF8&qid=1473874503&sr=8-1&keywords=noctua+120mm

     

    EDIT: WHOOPS! It was actually these ones, MemX. Hope you didn't order just yet.

    HUUUUGGGGEEE drop is fan noise.

     

    Will obviously not cool as well as the stock fans though.

     

    Awesome, cheers!

    <20dB is QUIET - my background noise level is something like 30dB in my place, IIRC.

     

     

     

    I can't remember what the flow rate is on the standard fans, I found them somewhere previously but it was amost a googlewhack :lol: 

     

    I think they're something like 100cfm??  Which is a LOT but I guess fair enough for an amp that is designed to be backstage at a gig, running 5kw of bass through it for 3 hours solid.

     

     

     

    EDIT:  Yep, found the specs - https://www.avforums.com/threads/fan-replacement-thread.1799166/#post-19561094

     

    Jamicon JF1225B2UR-R

    100.5CFM / 170 cubic metres per hour

    45.7dB(A) (!!)

     

     

    Given how underworked these amps usually are day-to-day when just at 'normal' volumes on music and TV, I think a change would be good... :D lol

  12. How loud does your bass need to be?

    Great post ^^^

     

     

    Sad to say that I've not been to many music events, but I can definitely relate to the comments.  

     

    I have been to an under-18s Jungle event (when I wuz young), which had something like a 20k soundsystem in what was effectively a village hall, and the inescapable, excessive bass was doing my head in after a while because my lungs were just vibrating out of my chest in every room in the building.  (The fact there were seemingly 7 year olds smoking did not exactly provide a 'quality' ambiance either...)

     

    I have also been to one of the superclubs in Ibiza once (I think it was Space, I'm pretty sure it wasn't Pasha) and while the music was literally crystal clear so didn't feel that loud once you were in there for 5 minutes and acclimatised, when we got out and into the cab, it was like we were wearing those enormous ear defenders and had to shout at each other.

     

    I'm surprised I'm not more deaf TBH but I seem to be able to hear to about 20kHz on those online test things, so perhaps I've been lucky.  It's just the raging tinnitus and intermittent ringing/deafness after loud noise exposure that is the annoying thing nowadays...

     

    Anyway, enough of my egocentric waffling.

     

     

    Other than the Red Rocks issue discussed in this thread, I do sometimes wonder how many venues actually tests their volume levels for reasonable-ness.  The Shpongle event described above sounds like it would clearly not pass any Health and Safety tests if they were actually enforced.

    I never figured a moving mass of 1Kg could do that!

     

    Don't be mentioning that on some of the 'audiophile' forums, they'll cry 'Heresy!!', round you up with pitchforks, burn you at the stake, then return to a nice dinner listening to their single 10" because, you know, 10s are lightweight and 'fast' ;)

    I saw Star Trek: Beyond at the cinema the other day. 

     

    I'm not sure if it's been graphed yet as I've not been online much, but the bass in the cinema I was in was virtually non-existent.  (Not to mention there seemed to be a distinct lack of 'sparkle' at the top end, like they'd lopped off everything over about 12kHz :mellow: )

     

    I'm hopeful that the lack of bass was just down to the cinema, and/or that the actual track is full bandwidth so didn't have the pronounced 30Hz hump that sounds 'good' <_< in cinemas.

     

     

    *awaits someone to come along and prove it's a terrible 40Hz filtered track*   lol

    Full BW effects simply don't give good 'Level' ratings with the current rating scheme. This is why I am including ZRMS, LeqZ, and ZPeak dB numbers. Brave comes in at 118.9dB ZRMS Peak. That's second only to TDKR. I think once I can get Z-weighted dB levels for all the films, we can re-do the Level Star Rating to be based on the Z-weighted dB numbers....

     

    Today's measurement:

     

    HALO4:Forward Unto Dawn:

     

    Level - 3 Stars (107.71dB composite)

    Extension - 5 Stars (6Hz)

    Dynamics - 4 Stars (25.59dB)

    Execution - A lot of cheese to sift through, but well done bass when it counted, and they saved the best for last. 4 Stars.

     

    Overall - 4 Stars

     

    Recommendation - Rent. Bad acting, not so good storyline, but if you are a HALO fan, worth a watch.

     

     

    JSS

     

    Finally managed to snare Halo4: Forward Unto Dawn for nice and cheap :)

     

    Watched it at the weekend - the Execution comment is spot on, being cheeeeeeeese-tastic for most of it :lol: but quite good fun, with a great ending bass-wise!

     

    Had to watch it with Dynamic EQ off on the AVR due to it being late at night and the neighbours who never go out being in :rolleyes: so will watch again with Dynamic EQ very definitely 'On' when they do actually have an hour out of the bloody flat...
