Her eyes look so disinterested in the whole subject

Why are you filming in 1080i??? Why Interlaced???? It looks so bad

Brilliant

I kept thinking about all the things he didn't say -- and realised how good of decision that was for this video.

You should do a laplace transform of the pulse response of the speaker input to laser output. This will give you the transfer function, and you have all the ansswers you need.

Damping factor

Really great breakdown!

Ooooo weeeee this was amazing 👏 🙌 😍 😭 ❤️

What sort of power does the infra-subwoofer demand? What is powering it?

What a posh way of saying I love bass !

Wow! This is the best

hi, not related to the subject , but i had a question and you might know much better , would a digital to analog conversion be better before , or after amplification ?

Does temperature affect these readings? During your experiment, did this need to be controlled?

Your content is fantastic! Loving the series and explanations. Thankyou

Can we hear both at the same time?

great explanation, thanks

pauzed at 5:37 ... I need a demo! don't let me down now!

Super great job! Can't help but to be curious what this could have looked like with the accuracy of 96/196kHz instead of 48kHz 😄

More than Avi (of Penthatonix), I was thinking about Bobby Bass and the nicknamed as "That bass voice"

Seems pretty self explanatory

Steve meade....about to install these subs all over his home

Let's just toast this driver here. See look how much it moves when we screw with the ported frequency...

Where can I buy one?

So does this mean the BBE sonic maximizer actually does something or introducing harmonics is just pleasing to our ears

There are distinct differences in the sound of these consoles. The older Yamaha stuff sounds less dynamic and midrange focused.

The small lead pressure spike is always negative due to the HP transient effect of the mic capsule measuring air pressure "changes" and not absolute pressure. This is why its referred to as a pressure gradient mic. An accelerometer coupled directly to the LF driver cone would output the wave form in phase due to lack of the unavoidable delay caused by the speed of sound with the air coupling of a measurement mic. If you looked at an extremely expanded time base of the accelerometer output, there is also a very small delay present from the speed of sound from the voicecoil initiating movement of the driver cone until it reaches the accelerometer. Obviously the delay is much smaller as the speed of sound in a solid is much faster than in air. If you look closely, the surround of the LF driver used in the test had a slight out of phase movement at the surround. This is the fundamental surround resonance. The spider also has a similar breakup mode. This guy is one of the first people who have attempted to explain the observed absolute phase discrepancy in the signal path of a typical pro audio setup. Some D to A stages also introduce a bit of pre ringing thanks to the digital filter. The latency is another issue often overlooked, which can be several ms in some systems.

Gostaria de ver ele cantando gengiskan

От этого голоса я сама завибрировала. Невероятно

30 inch sub💀

He levitates stones & Rocks with sound.

No one will ever be as good as j d summer...

All that talk for one note

3dB is double. Correct?

am I the only one where "acoustic pipe organ" drives me insane? seriously though... this is amazing. So many digital organs are totally ruined by terrible sound systems, with bass usually being the weakest/non-existent.

How would one test this when building subwoofer, mid and high range enclosures. Are there programs that can simulate the freq range and cancellation of enclosures?

And loads the driver down to...?

TRY THE LEWITT 640 REX CONDENSER AND DYNAMIC KICK MIC, SOUNDING MORE NATURAL THAN THE D6😊

Infra sound is a great way to manipulate people's emotions without them knowing. Perfect for a church!

🤜🤜🤜

Imagine playing sounds over a speaker instead of having real pipes 😂

@19:00 Speakers are an inductive load. At Dc they are shorts, at higher and higher frequencies they "open up". This is due to the physical sizing of the inductor and how the core saturates. Inductors also introduce a phase lag in the current signal which is why at higher frequencies you are seeing 1 pi radians of shift.

Now we know what really cause St John to write: "And behold, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became like blood. And the stars of heaven fell to the earth, as a fig tree drops its late figs when it is shaken by a mighty wind."

Would ny a proper mesurement be closest to where our ears are in a listening session? Distance does play a massive role on very low frequencies. Althought i do get the point of this experiment, which i respect the effort.

when the priest is a basshead and needs an excuse to buy massive subs

I love audio but this is totally over my head. It’s awesome! Thank you for your videos.

So cool

Friends don’t let friends put an electronic organ in place of a pipe organ.

Gotta admit, I was surprised that the lowest voice record is held by a white guy. Awesome voice and great control - a true professional! I bet the headphones were playing the mic input at at least an octave higher

fake. sound waves don't exists

I like this video, I am new with speakers. I think there is an error at 5:31, the 8 ohm on left below the amp should be 16 ohm? Also, I would think you would want to measure things with one speaker at one volume level, then while measuring, turn up the volume to get 3db increase and see how much voltage and current are needed. Then you have a response curve to test against the equations. Maybe I missed that but seemed like you were keeping at same volume knob level setting the whole time.
