  • We construct a pair of large Voigt speakers. I explain the principles behind ported, transmission line and horn based loudspeakers, demonstrate these speakers in our anechoic chamber and use constrained layer damping to build an enclosure that is superior to commonly used MDF.

      @@warrenbell950Depending on the vintage speakers, there is a good chance that the cabinet resonance was leveraged to augment the drivers - the crossovers may also have been chosen to address cabinet resonance. I generally wouldn't recommend it as a treatment for vintage speakers - either they are good, and you stand to ruin them, or they are bad, and they aren't worth the effort IMHO. DynaMat is a choice, but not as good as the 2part treatment he used - you can also pick up a similar material from box stores used to line potable water tanks - it is nearly identical and has the same properties; you can also buy smaller quantities for testing. I personally don't love VT speakers, but the science behind them as well as the wonderful detail of the video makes this a fantastic choice for an educational channel! Love it!

      @@MotivatedMetalworks You'll get no argument from me on anything you've written. Nevertheless, it is more than a mere matter of convention, that we derive specifications for speakers. It is the method by which we compare one loudspeaker to another. Even beyond that, given the level of detail and science brought to bear in this presentation, is absurd to leave out any measure at all, by which a viewer could assess the success of the endeavor.

      @@johnny7254 fitting those beasts in his chamber isn't possible, so any response curve presented would be flawed.
      However, he could play them outside and get a pretty good idea.
      When I build speakers, I try to balance the drivers across the spectrum, and crossover points based on where the curves are most beneficial at the natural roll off points. Once that's done, I design the enclosure to meet my goals - is it a sealed box with no deep base, or can I tune a port to hit another octave lower?
      I don't agree with the channel's logic or validity testing on material weight/stiffness as the accelerometer was measuring an impossible occurrence with the thump test. Also, floor weight of speakers is a moot point for most applications (outside of aircraft, boats, and possibly cars), while size is often a critical design element. Doubling the speaker walls increases the outside dimension, as the inside is a calculated and highly constrained space. In most cases, MDF with proper internal bracing will outperform the same thickness plywood, while benefitting from a lower cost.
      Transmission lines and horns in general are the exception, but he doesn't state this or why - you can't brace a horn like a ported box, because you'll fuck it's performance up. So in these enclosures, you need stiffer materials.

      @@johnny7254 Something else comes to mind when thinking about this video.
      About 30 years ago, Popular Mechanics had an article teaching the reader about transmission tubes, and how you could build a subwoofer out of a 4" Realistic (Radio Shack hadn't fallen off their original business model yet, at that time) woofer and PVC fittings.
      What the article failed to disclose is that while the micro sub would hit 40hz, it was anemic and not musical sounding doing it.
      Planars, infinite baffles, and line arrays all have impressive sonic qualities while also suffering some significant drawbacks. Voigt enclosures aren't exempt either, as they tend to lack authority in the bottom end, or as with folded horns, end up being gigantic enclosures to play through the whole spectrum.
      Voigt's share a commonality with planars and infinite baffles, in that the linear distance from the edge of the cone and the port will have a direct impact on where phase cancellation occurs.
      At the end of the day - there is no perfect speaker enclosure, and we need to balance our designs with regards to perfection and reality and hope we can afford the point we wish to land on between those two ends. :)

    I guilt a pair of Voigt Pipes very similar to those in this video about 15 years ago. They sounded very good, especially in terms of mid-range and soundstage. The mid-bass was also sufficient but could likely have benefited from addition of a sub-woofer for added slam. Eventually, I added a tweeter to add "air" to the system. Fostex produces a broad line of appropriate yet affordable drivers for this and similar designs.

    I really liked the explanation of the end-effect reflection. In transmission line theory it's just talked about as an impedance discontinuity but for resonant tube design (think wind instruments like flutes) the resonant length of the tube appears slightly longer than its physical length. That high pressure node that the sound reflects off of occurs not at the exact end of the tube but slightly beyond it, which is easy to understand if you visualize the pressure changes in the air and the non-negligible response time for the surrounding air to rush in to fill the low pressure void emanating from the end of the tube.

    I must say, those speakers sounded pretty good through my speakers.

      I flip to my Schitt Modius Dac, 1/3W OTL Tube amp and some Sennheiser HD600's for his playback example - like I'll get to hear HIS speakers somehow lol :D

      I think you mean that MICROPHONE allowed those speakers to sound decent through your speakers? (Everybody forgets about the microphones.)

    I love this channel!!! Imagine how differently school would be viewed if teachers were half as good as this guy. (Never going to happen, but what is cool, is that unlike the education system, the best can be shared to anyone/everyone) CZcams for the win!

      Guess I was pretty fortunate, as the science teachers I had in High School WERE this good, and were such a tremendous inspiration to me that 40 years later I still can't get enough! I don't doubt my last breath on this Earth will probably happen when I'm watching a science video or tinkering with some nifty new technology.

    Your channel has exceeded on basically level I'd measure, and it was stealth.
    Tech Ingredients is an amazing channel...it's WAY better than my first few viewings shallowly concluded.
    YOU REALLY DO YOUR FREAKING HOMEWORK, and it pushes your content from, "oh, that's nice" to "Gloss over this to your detriment."
    Wow! THANK YOU!

    Thankyou, I have been interested in high end audio for several decades, both making some diverse stuff and spending far too much buying stuff 😂 .. but this is by far the clearest deeper explanation of this type of speaker I have come across

    -It is cheap
    -It is easy to machine, it's cheap
    -It is relatively inexpensive and easy to obtain
    -And it's cheap
    And did we mention it's cheap?
    I don't think I can ever stop smiling after that.

      ​@@JesusFreke Relatively, yes. He explains this in the video. It's why fibreboard is used in so many cheap wooden things these days. For example, my desk is LDF and the speakers I used to haul as a DJ had a MDF enclosure.
