    2 RE AudioXXX 18d2's

    Two left. Both are the overhung version 2 which has much higher motor force and the RE logo. $475ea shipped or $400 each local pickup. I will drive a bit to meet.

     

     

     

     

    Chane Audio SBE-118 and a Chane VBE-118.

    Both are passive cabs with a single Eminence built 18" driver. SBE-118 is sealed (Roughly 22" cube) the other VBE-118 is slot vented and tuned to the 17Hz range (Roughly 23x23x36"). Local pickup preferred. $100 each! I will drive a bit to meet provided gas is covered. Someone PLEASE take these! I'll ship these if someone pays the shipping! Does anyone know a broke, young or otherwise financially strapped person who can't afford much? This is basically charity at this point. Anyone know of a struggling audio enthusiast in need? 

     

    Awesome offers on these B)

     

    It's a shame there's a rather large pond in the way as I'm sure I could find the money and a home for the latter!

     

     

     

     

    JL Audio 10W3v2

    Pulled out of my stealthbox in my Jeep WJ. Needs a good home. Good condition. $40 + shipping or $40 local pickup.

     

    Hmmm...  I have one of these sitting in a small sealed boombox that used to be in a car...

     

    I wonder if I could make a small PPSL if I bought this one? I recall they sounded pretty good...

  6. Upcoming Testing Possibilities?

    I'm going to try it out. Probably a single channel on both first to see what happens. Remember I'm testing these in about 2.75ft sealed per driver so it takes a lot more power to get them moving versus the Othorn and the average impedance is way lower. If that works out all right I may try both amps in the 12K connected one to each driver. I'm a little worried on that since it's a 1ohm min load on each and the airspace is shared. If one side of the amp protects or limits slightly before the other that could cause a catastrophic instability for the drivers (suddenly becomes a very high tuned PR enclosure in the middle of a very high power measurement. :o )

     

    That sounds like it could get expensive real quick... :wacko: lol

    Valkyrie (5.1 DTS-HD MA)

     

    Level        - 4 Stars (110.86dB composite)

    Extension - 5 Stars (1Hz)

    Dynamics - 5 Stars (32.47dB)

    Execution - 5 Stars (by poll)

     

    Overall     - 4.75 Stars

     

    Recommendation - Rent (by poll)

     

    Notes:  Interesting sound design - it has LOTS of scenes with effects below 20Hz.  This movie is very loud sounding because of the dynamics, and it's not a bad movie, either.

     

    PvA:

    I finally got round to watching this tonight after I picked it up for cheap ages ago - I liked it, I liked it a lot.

     

    Excellent dynamics, had it up about -10, whereas I usually have it about -16, and the speech volume was spot on while the sound effects were suitably loud without being ridiculous.

     

    Great bass throughout and good use of the dynamic range, I will re-watch when I finally calibrate properly because some of the aircraft sounds were already weighty and I know I'm missing a lot of bottom end!

    Also found a few sleeper movies... Can't remember them all, but the most recent one was The Exam.

     

    Didn't like the movie very much as the ending left much to be desired, but many did enjoy it. Similar to Phonebooth/Devil in terms of cinematography, but the bass reminds me of Pulse Server Room, powerful rumble/throbbing effects. Short movie, worth a shot.

     

     

    Is it this one?

    If so, I think I'll pick one of the cheapies up secondhand :)

    That's too bad.  I forget where I read about it (and can't seem to find it on Google), but anyway.  There's supposedly a camp in the Himalayas where climbers have been known to die mysteriously when storms passed through.  Storms that should have been survivable for experience crews wiped them out.  Investigation and interviews with survivors led to the understanding that something about the conditions in the environment caused many among the crews to literally panic and disregard precautions (like staying sheltered during the worst of weather).  In the end, the best explanation offered was that nearby rock formations formed a resonant cavity through which the wind flowed through to produce intense infrasonic sounds, and that the mountaineers, lacking familiarity with high intensity ULF suffered from immense confusion, became consumed with panic, and then froze (or fell) trying to escape their predicament.

     

    I guess it sounds like a bit of an urban legend, but I think it's noteworthy nonetheless.

     

    I think infrasound is a rather unexplored area that deserves more attention - even back in ancient times, I believe that it was used to elicit an unusual physiological response:

     

    http://orkneyjar.com/history/tombs/tombacoustics.htm

     

     

     

    The principle of "Helmholtz Resonance" - the phenomenon of air resonance in a cavity – was found to apply to a number of prehistoric cairns.

     

    The most commonly-used example of this phenomenon is the noise created when blowing across the neck of a bottle. Maeshowe, for example, shares the same basic structure as a bottle - an air filled chamber connected to the outside world by a long, narrow neck.

     

    To create this effect, the users of the cairn had to create a sound that was at the correct frequency for the dimensions, and design, of the chamber. The larger the chamber, the lower the pitch required to create the effect and, therefore, the slower the required drumbeat.

     

    In Maeshowe, a drum was used and the researchers discovered that the correct frequency was 2 hz. This is an "infrasonic frequency" which means that, although inaudible to humans, it can be felt as distinct physical, or psychological, sensation.

     

    Test subjects reported the feeling that sounds were emerging from inside their head and body. They experienced feelings of dizziness, nausea, headaches, flying sensations and also that their pulse-rate was being affected.

     

    Dr Watson suggests that prolonged exposure to these "sounds" could have had a profound effect - an effect that Neolithic man could only ascribe to the supernatural.

    I love Super-8 as a film but bottom end is a letdown :(

     

    Will look forward to the Martian getting cheap so I can buy it! :P lol

     

     

    EDIT:  Ooh, I forgot - I watched Automota the other night.  Pretty good film and I liked the sound design.  I don't think it's been measured yet (although I can't see the GoogleDocs spreadsheet on this laptop as, you know, I might be trying to give away all my workplace data so can't possibly be allowed to even look at a file sharing site :rolleyes:).

    Thanks for the graph and comments, it sounds promising!

     

     

    ULF Highlight (for those that can resolve it: 1:02:00 to 1:07:30.  It is there on purpose, and a small room with lots of displacement and 3Hz capability will know it is there.

     

    I can't believe any mastering studio has this sort of capability :huh:  so kudos to the sound designer(s) for including it, knowing most will never play it back!
