  1. Haha 😃 I think the psychoanalysis was perhaps more internally focused as I found myself reading the ad several times trying to wrap my head around what might have the slightest bit of merit in the claims... I've recently been introduced to the concept of PIM (Passive Intermodulation Distortion) which occasionally turns out to be quite problematic in cell phones: https://www.anritsu.com/en-us/test-measurement/technologies/pim The basic idea is that you can get Intermodulation Distortions from the non-linearity created at the mechanical junction between two conductors. The fundamental mechanism isn't well understood, but there are plenty of empirical solutions for it. Perhaps we should try this magical elixir at work to see if our PIM goes away? 🙃 In other words....perhaps there is some merit.....and we wouldn't want others to think $599 was too cheap for the near perfection we enjoy in our homes...
  2. Perhaps the same thing that had you perusing in the first place? If you know what you're looking/shopping for, then you probably don't explore the fringes? So perhaps there's some unknown need not being met that is fueling a mind open to new discovery? And writing about it is perhaps a means to subdue this anxious curiosity?
  3. So is it safe to say Delphi was wrong? Waymo One is interesting, but it's in a dedicated city and I believe it has a team of people in remote control of the vehicle...so it's not fully autonomous although it looks like it. That autonomous system costs a lot more than $5k though.... But I do think the only autonomous vehicle model that makes sense is a rideshare / taxi type service. This way the burden of maintenance goes onto the vehicle owner, which is paramount to autonomous safety / feasibility.
  4. Standing waves have very little to do with headroom and overall output. My reference to PWK was about a Dope from Hope article or maybe an AES article where he talks about the mathematics of damping and his obsession with efficiency. The reason few companies dampen the interior of the cabinet is because it saves money. The audible effects are secondary to other larger concerns; same story with baffle edge diffraction. It is however very easy to measure internal standing waves (and baffle effects). It is also easy to hear the difference when they're mitigated. These things are in the last several percent of what matters to the overall sound quality. And it doesn't take much to get enough damping (point being don't over dampen because that's a waste of energy.... again back to the last percent of performance). The audiophile path is about tweaking out every last drop of performance. The speaker business path is about performance per dollar. That dollar might be better spent in other ways from an engineering perspective - especially in the pro cinema world where the effects are much harder to hear and dominated by the big screen in front of the speakers. On the other side of the coin, it's really cheap and easy to stuff a cotton pillow into a cabinet to hear the differences. If you want to be fancy you can use Owens Corning 703 and install it all proper like. I spent years measuring magical speaker cabinet shapes. They all resonate and have standing waves. Even the ones with magical shapes based on magical equations still resonate. The most direct engineering solution is damping. I wish it was a cooler story but that's the way it is.
  5. Nope. An inch for every foot is a general rule thrown around, but even that doesn't work. Sounds travels in all directions so you'll get tangential modes, etc. The best thing to do inside a cabinet is use absorption. PWK would argue that absorption reduces efficiency. Although that is technically true, I firmly believe the 0.1dB trade-off for way lower resonances is worth it.
  6. Haha mine too. There gonna be new content? (new speakers). I haven't been on the forum in years...
  7. Oh shoot - are you saying the X32 is outta the price range? What about the X32 Rack at $1k? The Behringer XR series isn't horrible, but he will quickly outgrow it. The XR12 is $250 and the XR18 is $600. They have fewer mic-pre's, but the same general USB recording capability, and can only be controlled via iPad.
  8. Oh, I forgot to mention the Allen & Heath Qu32. I believe it has a DAW controller driver available for it now. That might be something to consider in comparison to the X32. Ya, Dante is amazing - but you get the same functionality out of the box with a single USB2.0 cable to the computer. You're just limited to 32 channels. The Dante starts to make sense when channels counts get larger, or you're trying to send a bunch of digital data over a long distance. The USB only works when the computer is next to your console. I don't think the Qu32 has a Dante card option though. The X32 and TF5 definitely do. The QL consoles are a big step up in price from these other guys though. I think I'd personally make the jump from TF to CL unless I needed the automixer function built into the QL.
  9. I couldn't disagree more! The wireless interface that you get with an iPad removes one of the biggest shackles for a sound engineer: the location of the mixing console. I've been doing a lot of sound training lately and I gotta say it's soooooo much easier with the iPad. We get to talk around the room talking about and experiencing how the sound changes everywhere, and then learning to mix for the whole room. Walking up to a monitor on stage and hearing what the musician hears is one thing....being able to adjust it live brings entirely new meaning to the learning sound engineer. I use this all the time to teach "referencing the mix".....and learning how to correlate the booth mix to the stage mix for the musicians. Don't get me wrong - I'm a curmudgeon old fart that wants his analog knobs back, but the ability to move around while mixing is such a pleasant change of pace. I've intentionally done entire concerts (40 channel live recording mixes with realtime patching swaps, delay feeds, monitors, etc...) with an iPad because I could sit in a better location. However, I totally agree that it's best to learn the basics. Just because your console has comp/gates and crap tons of FX, EQ, and other processing doesn't mean you should be using it. 80% of the mix happens with mic placement and speaker configuration. 15% is faders and gain structure, 4% EQ, and that last 1% is the other 90% of the processing in the box.
  10. Behringer X32 I currently have both the X32 and Yamaha TF5. I also have extensive experience with just about every digital console out there. The short story that nobody wants to admit is that the X32 sound quality is very competitive at every price point. You might be surprised how many installations have ended up with the X32 - even when budgets weren't a factor. The biggest reason I recommend the X32 for dual live sound / recording is because you can also use it for DAW control. So instead of mixing on your computer with your mouse, you use the faders on the console to adjust the mix in the DAW. https://music-group.force.com/musickb/view/article/behringer/X32-Can-The-Console-Be-Used-As-A-Control-Surface-For-A-DAW The TF5 doesn't have that feature. The only reason I picked up a TF5 is because the user interface was more intuitive for the volunteer staff at my church. Both have iPad control, but the X32 iPad interface is way way way better. In fact, it's better than any other digital console out there. It's even better than the X32 console interface. As for the DAW, I would recommend Reaper....mostly because it's free. But if you're gonna spend money, then go with ProTools. It's what everyone uses these days and you'll be able to use anything else after learning it. You will probably come across recommendations for the PreSonus StudioLive and Soundcraft Si series, and you'll find a lot of people happy with them. However, I have yet to meet someone that has used all four consoles and preferred either the PreSonus or Soundcraft. They just have some really odd annoying quirks, and don't have anywhere near the processing power of the X32 and TF5. The next step up from those four would be the Yamaha CL5, but that's a totally different price point. Oh, and don't bother with the Behringer XR lineup. If you want to save money, go with the X32 Rack and a large screen iPad (older generations are totally fine for that). There's an Android app too if you do the android thing, but not for the Yamaha consoles.
  11. If you think this angle affects the point I'm trying to make, then I'd suggest I may not be communicating clearly, or maybe you're not understanding what I'm trying to get at.
  12. Show me one study that says Class III autonomy is safe. I've read two peer reviewed studies that show that it is less safe than no autonomy.
  13. Happens more often than you'd think, although that's not the point I'm trying to make. My emphasis is that it is possible to differentiate between the known and unknown: There are problems known about ahead of time Or there are problems due to ignorance (unanticipated variables). I take great issue when known problems are ignored - especially when human life is involved. And that is precisely what is happening here. There is also due diligence in trying to uncover as many unanticipated variables as possible, but that's detracting from my point. It's one thing to forgive someone of honest ignorance, but it's totally different to forgive someone of "willful blindness" or "cognizant recklessness". If someone like myself, with no official involvement with autonomy, is able to be informed well enough of the dangers of Class III autonomy, then how is it that Tesla and Uber are completely unaware? If they aren't reading this research, then they're not doing their due diligence to understand their design well enough....which is immoral. And if they are doing this research, then they're completely ignoring it, which is also immoral. Class III autonomy isn't a stepping stone. We don't need cars running around killing people to prove what we already know before a single car hits the road. If the airline industry engaged in the same willful blindness, then that was an unnecessary cost and absolutely should not be cited as an example of how we should expect these things to evolve. Give me one good reason why we shouldn't set the bar for our expectations higher? It has been my experience that when we set the design bar higher, that designs actually get completed faster.....and better. And then cost reductions follow very quickly because the designs are actually fully understood. Faster, better, cheaper....this has been my reputation for the last 10 years of official engineering, and has also been the reputation of those smarter engineers that I've been trying to learn from. Despite all the naysayers and low bar setters and lazy engineers, ignorant managers, etc.... There is a design philosophy better than this 'million of miles' nonsense that you're trying to tout.
  14. The annoying part about your scenario is that the statistics won't capture events like this because you weren't involved in the accident. That brain dead automatic braking system that will gloat about prevented fender benders won't accurately depict the fender benders it caused. I can't even begin to count the number of times an automatic braking system would have caused me an accident. The only people that believe in such systems are those that don't understand how to control a vehicle (and many of them aren't even aware that they don't understand). Maybe we should start making guns that have automatic aim and trigger pulling ability. This way the users of the gun don't have any responsibility to learn how to control their gun, and we can solve all violence that way!
  15. Exactly - profits at the expense of life. That reasoning was supposed to have died off after the industrial revolution, but apparently it's okay today if you fabricate a rockstar persona around the bad ideas.
