Excellent explanation (in layman's terms) of how speakers work. It still amazes how the recording and playback of audio works. But it does, and works wonderfully! A video featuring your speaker line up and tidbits of their history would be much appreciated! Thanks for your contribution to audio.

Great instructional video. I had zero understanding how a driver made noise before watching this. The one question I have is how does a speaker transition or pass off the low-mid from the woofer to the high tweeter? Is it inherent with the limitations of each driver or does something else manage this. I'm probably not using the right terms but essentially how does the tweeter know what parts of the noise it should play vs the woofer?
@GG-kc6ie2 жыл бұрын
Of course I typed out the question and hit send only to find that you explained everything in the next video 🤦♂️ Thanks, great tutorials, it's really fascinating stuff. When you said earlier the technology has been around for 100 years it blows my mind thinking about the moment somebody discovered their invention could actually reproduce noise accurately, what an incredible moment.

This is probably a jr question but, when building a driver how do you determine the sensitivity and load (4,6,or 8 ohm) of the driver? And can it be changed later if you decide it’s not meeting your requirements?

you must make one about the resonances and that they have a specific sound, a midrange made from plastic sounds completely differently than one from paper. And maybe you can explain why it is not too bad to go with plastic in the bass and what's the advantage/disadvantage there but plastic in the midrange is something to be better avoided.

Hi John, from a structural standpoint I would think using a larger voice coil would make a woofer or mid woofer more stable, I realize there are trade-offs in most engineering but I’m not sure what they are. Cost/ Driver efficiency?

I'm still surprised that if I walk past a venue where music is being played, like a bar, then it's always possible to tell whether the music is live or being produced by a speaker system. Still a very long way to go, I suggest.

Interesting, it still is a bit of a mystery to me how electricity can cause beautiful music, I believe it is the frequency of the electric signal that produce the frequency of the music, but maybe i am totally wrong, grtz from the netherlands

Hopefully the suspension surrounds that you use in ALL of your very expensive (IMO) speakers are NOT made of foam!!! In terms of longevity, foam surrounds will, without exception, deteriorate within several decades, if not sooner, and will not last as long as virgin rubber or doped cloth which seem to never deteriorate. Virgin rubber and doped cloth obviously cost more but these have been shown to pass the test of time as I'm sure you know!!!

@mrfudd133 жыл бұрын
Your analogies are a bit tortured - you could have just said tube, instead of coil-former,which sounds odd. A speaker is a transducer, not a generator - yes you can make it produce a little voltage, but basically it changes one form of energy into another. Saying it's just like a generator is confusing.
@meinwarcrafttagebuch51422 жыл бұрын
;-) I thought the same, why not comparing it to an electric motor and then to a linear electric motor, a generator is a bit off, but coil+magnet+movement=current is the idea and I think it came across.
