Great video. It's curious that great violins, besides their tone, are also excellent at projecting sound at a distance.... Corner loading is so interesting: perhaps also due to the diagonal setup, but beside the obvious boost, I get less bass cancellation and standing waves, at expense of image depth (in stereo, mono depth is entirely unaffected)

I really, really enjoyed your presentation of basic concepts. Looking forward for the next episode! Thank you for taking the time to share your knowledge! I am an avid book reader, but that gets dry and fatiguing. In fact, I have a very basic Italian book on Architecture which is simplified like this for various types of structures, and as an engineer I learned so much reading those fundamental concepts I wish I had read that before I delved deep into the mechanics (statics, dynamics and strength of materials) before I got bogged down into the mathematics. Keep up the good work! I'm a fan...

Amazing. Thanks!

Great

Great video! I’d really love to see more in this series. Particularly with respect to the physics of sound. Is there a part 2 yet?

Great video, I been reading about Voigt. But not much about his actual designs is available. Your stuff is technically enough, but easy ti follow for a layman. On to video ll.

Excellent. Really appreciate the walkthough from the first principles.

Excellent video. I used to own a National Duolian resonator guitar from 1936, which basically had a horn instead of a sound hole in it. It was obviously an acoustic unamplified instrument, but it was loud! So, is an instrument like a trumpet acting like a transmission line or a folded speaker with a driver with a horn at the end of it? Thanks, Janos!

So.. is saying ‘horns match the impedance of the driver to the air’ kind of a redundant statement? That would be the case if it’s simply directivity=efficiency, I would have thought.. With small bass horns, like a small front-loaded bass horn, the mouth is often too small to provide significant directivity, and yet the lower frequencies are amplified. Genuinely interested if someone can clear that up for me 👍

Hi, is there a possibilty to use a normal Tweeter in an horn?

Wow! Exactly what I was looking for. Simple explanation & good presentation. This video series should have way more views. Thanks for the upload, I will share wherever I can. Keep up the good work! 👍👍

How did you come to say that the fundamental frequency of lighting is 100Hz? I google searched around for this and closest I found was talk of Florissant lightbulbs at 100Hz. Can you point to a reference or reasoning for this?

Nice video but the information is incorrect. Often you are describing “wave guides” rather than “horn loading”. To understand this better, look up acoustic impedance matching and compression. Without compression, there can be no horn loading, and therefore no impedance matching between the sound source and the listening area. That’s what makes a horn. Regarding the conical shape of many driver diaphragms, the reason for this is to make a rigid yet light weight piston to push and pull the air molecules in front (and behind) the diaphragm. Rigidity is needed to avoid mechanical distortions in the sound we hear, and low weight is needed to reduce the amount of energy required to move the diaphragm forward and backward quickly. The diameter of the “throat” of a driver, ie the voice coil diameter, versus the “mouth” diameter has no direct relation to the frequency range produced by that driver. In short, in and of itself, no driver is a horn.

Put the speed to x1.25. Thank me later
