Servodrive Contrabass mechanism in action 

Listen to Bass We Like You (Subwoofer Test) by EmrE_BuLSaT2 on #SoundCloud soundcloud.app.goo.gl/KkCL6

Ive got no idea about servo drive subs , First time I actually seen this type of driver . Ive hired a few big pro systems before and I now I feel schooled on what's actually going on front of house . Cheers

It appears the algorithm has once again brought us all together.

An Excellent Engineering Example on how to translate rotary motion into linear motion in a balanced fashion!!!😁👍🏻

"Music is just wiggly air"

had to view 3 times before i figured this out... this is.. definitely some creative engineering.. id love to hear this unit in person.

What a facinating looking (and sounding) mechanism!

Hi Marcus, the sound is pretty amazing, although when listening on low / very low sound level and using a crossover frequency like 40 of 80 Hz it makes some buzzing noise. But when listening a little louder its normal. I use 20 -25 Hz crossover frequency and when watching movie the sound is really awesome. Movie 6 underground has some mind blowing subsonic sound effects that makes my couch vibrate a little. I also think the subwoofer does add value to music. The bass drum is now a lot more realistic, my speakers will play music down to 26 Hz. But even then i think the sub adds value to the sound stage

I am 30 years old and just found out that you can make subwoofers with servos. Mind blown!

Usually with servo woofers they get down to such a low the human ear can't hear it but our bodies can feel it, that's why a lot of rap artist use these servo woofers aka 808 for concerts and why the bass is so heavy, you don't want to use this exclusively for a concert though as the bass is very blaty and sometimes comes out muffled that's why they're accompanied by the EAW SB1000 series woofer as they deal well with the midrange and lower bass areas very well, and mainly get used on the flypacks on the stage.

It sounds like a lot of harmonic distortion present. My woofer is a servo type with a 4 inch diameter voice coil that has total movement of 2 inches. It reproduces with less than .1% harmonic distortion. It's top frequency is 25 cycles! Above that the normal woofers take over.

I never heard about Servo Drive... But, It's very cool! Nice video man, Greetings from Brazil!

this looks pretty cool

This is so dope!

That is f..king amazing 🤩

That's very clever !

Sounded great on my phone speakers

Interesting 👍

Lmao I watch a lot of machining videos and based on the thumbnail I thought this was a weird machining process for that rod in the middle. Took me a sec to realize what was going on...

ServoDrive in the 80s, the energy seemed more outside than in the club building, probably the whole building resonating. Used a Honeywell servo motor good for abut 600 watts after that the motor is toast. 2 Ohm load, only ment for deep bass, very narrow bandpass.

My right ear enjoyed this better than my left

How does it sound? It doesn't look light and sensitive enough but I haven't heard it so who am I to say.

please explain? Is this something about tying the speaker cones together to mechanically pair the bass? The linkage creates a physical pairing between the phases of the speaker vibration?

I'm literally 69,420 person to watch this video. Holy jesus.

What am I looking at? How work?

This is literally a better driver as it can get throught high voltages but you gotta change some pieces after some months.

Would it do better with a brushless motor?

Yea I have no fuckin clue what I'm looking at. The algorithm brought me here for some reason.

Muy buenos, en la compañia donde trabajaba tenian 4 pero eran muy pesados para 400 watts. Los cortaban a 80 hertz , en fin ahora es el turno de los power soft con sus infra de 30 y 40 pulgadas

Pretty cool. Seems like the too drivers a slightly out of phase.

How does this compare to a rotary woofer, for reproducing frequencies in the 0-20Hz range?

I searched for this

Hold on a second please reply to this. I want to know something so the little thingy right there two little thingy that holding on those subs the little metal pole does that move and that makes frequencies like little vibrations and then it passes onto those witches big ass so it’s gonna make a bigger frequency then that passes on over to the subwoofers by cone that way it will make it move and also project the sound.

But how can the servo respond fast enough, nor have enough torque?

looks like RU-vid started recommending this video

Name of song?

Is this the same mechanism that use the devialet phantom's?

Let me try on small scale with hdd head mech. N sub cone

I bet you are fun to live next to.

Song Name Brooo 🤩

Almost made it through the whole vid before I realized it was killing my speakers

Can you link the song too??

Is that rod what powers the cones or is it just a cone position sensor?

What is name of song?

Servo motor

I'm waiting for someone to use a fanuc motor.

Anyone knows the name of the song?

This is what happens when your stepper turns into a dj instead of an engineer

Wow is each side considered a driver? And they're belt driven?

What is it?

this system preceded powersoft's m force..

What song did you use?

Hey, whats the point of using a servo and all this complex mechanism? Couldn't you just as well link the two cones together with a rod to which permanent magnets are attached and make coils run around, like a linear motor? Thank you

isnt that too low???

Yes, it vibrates. No, it is not part of any kind of music. Sorry.

What is the point?

Wtf. How servo can do 200hz perhaps. I need to dive into this topic 😂

You could make the armature with less mass to reduce the work the servo must do to reverse direction. Maybe carbon fiber?

This is a supremely weird way to drive a speaker.

Ни хуя не понял, но очень интересно!

Isn't a contrabass à musical instrument?

what's its frequency range? doubt it will get to 80hz

Damn yall audio engineers need to chill before you start accidentally breaking the earth

What in the actual Fuck is this thing!?!?!

Что здесь происходит?)) Серводвигатель в роли катушки с магнитом?

tkatkatkatkatka

So his job is to rattle…

Umm... Umm... Hahaha?
