Building a Modular Spring Reverb Wall: Design and Material Analysis

00:02The story got to move on. Once we got The story got to move on. Once we got rid of the one side of a cube rid of the one side of a cube rid of the one side of a cube and have the spring unit based on the and have the spring unit based on the and have the spring unit based on the L-shape profile, L-shape profile, L-shape profile, the next reasonable question is how much the next reasonable question is how much the next reasonable question is how much how much further can we go?

00:40>> As always, >> As always, I got something for you. I got something for you. I got something for you. The the the first test, the original The the the first test, the original The the the first test, the original test with this corner was quite test with this corner was quite test with this corner was quite positive, I would say. positive, I would say. positive, I would say. The transfer function of the zinc-coated The transfer function of the zinc-coated The transfer function of the zinc-coated steel was that test was good, the steel was that test was good, the steel was that test was good, the transfer function was good. So, I made transfer function was good. So, I made

00:58transfer function was good. So, I made what has to be done. I I I did what has what has to be done. I I I did what has what has to be done. I I I did what has to be done. I done has what has to be to be done. I done has what has to be to be done. I done has what has to be done. I do be done. done. I do be done. done. I do be done. So, all in all, at the end of the day, So, all in all, at the end of the day, So, all in all, at the end of the day, we got we got we got the new built new concept, call it the new built new concept, call it the new built new concept, call it whatever, and it's this.

01:49The The reverb, the wall of springs. reverb, the wall of springs. reverb, the wall of springs. And the rest is, well, just a logical And the rest is, well, just a logical And the rest is, well, just a logical continuation. continuation. continuation. I mean, do I have to explain anything I mean, do I have to explain anything I mean, do I have to explain anything here? here? here? Let's not Let's not Let's not wait for anything. wait for anything. wait for anything. I have few springs on top. And since we I have few springs on top. And since we I have few springs on top. And since we have a pre-made holes, it's uh fairly have a pre-made holes, it's uh fairly

02:13have a pre-made holes, it's uh fairly easy to secure the springs. So, let's easy to secure the springs. So, let's easy to secure the springs. So, let's just uh

02:32Or, I'm going to put the mic a bit or Or, I'm going to put the mic a bit or I'm just going to put it a bit closer to I'm just going to put it a bit closer to I'm just going to put it a bit closer to the mic.

02:46Acoustically, we're good. Acoustically, we're good. Obviously, contact mic, it's your time, Obviously, contact mic, it's your time, Obviously, contact mic, it's your time, baby.

03:15>> I love it. Look. >> I love it. Look. One hit. One hit. One hit. Okay? Okay? Okay? And the amount of tail, the amount of And the amount of tail, the amount of And the amount of tail, the amount of sustain this structure is carrying is sustain this structure is carrying is sustain this structure is carrying is just just just unbelievable.

03:43>> And I can stop it. So, it means that >> And I can stop it. So, it means that it's just springs it's just springs it's just springs taking the signal from the frame and taking the signal from the frame and taking the signal from the frame and continue carrying it inside these wall. continue carrying it inside these wall. continue carrying it inside these wall. Who? Who? Who? Inside this Inside this Inside this wall of river is just this is amazing. wall of river is just this is amazing. wall of river is just this is amazing. So, So, So, cube cube cube is fun. is fun. is fun. Cube is it's nice looking. We have this Cube is it's nice looking. We have this

04:10Cube is it's nice looking. We have this light form and everything. light form and everything. light form and everything. Uh Uh Uh it turns more into it turns more into it turns more into construction. construction. construction. So, I going to take that off. It turns So, I going to take that off. It turns So, I going to take that off. It turns more into more into more into uh uh uh just kind of a Lego.

04:34Contact points we have Contact points we have in most of the places they match. in most of the places they match. in most of the places they match. Sometimes you have to figure out the Sometimes you have to figure out the Sometimes you have to figure out the order how you going to assemble [music] order how you going to assemble [music] order how you going to assemble [music] uh this structure.

04:57As I was saying earlier, As I was saying earlier, this is our

05:08And And for this build, it is very loose. for this build, it is very loose. for this build, it is very loose. >> [music] >> [music] >> [music] >> And I was thinking that that's going to >> And I was thinking that that's going to >> And I was thinking that that's going to be a problem, but the combination of two be a problem, but the combination of two be a problem, but the combination of two washers like M6 washers like M6 washers like M6 and [music] and [music] and [music] M8. M8. M8. And I also got M10 washers. This And I also got M10 washers. This And I also got M10 washers. This combination [music] combination [music] combination [music] is really good. Big juicy good.

05:38good. And these [music] two bad boys, there And these [music] two bad boys, there And these [music] two bad boys, there you go. you go. you go. So, you can make a So, you can make a So, you can make a you can cover a pretty [music] big you can cover a pretty [music] big you can cover a pretty [music] big surface now with this combo of two surface now with this combo of two surface now with this combo of two washers [music] and if you want to go washers [music] and if you want to go washers [music] and if you want to go even further, even further, even further, you can replace M8 with you can replace M8 with you can replace M8 with 10 and then you got a very secure

06:0110 and then you got a very secure 10 and then you got a very secure situation. [music] I need to tell one situation. [music] I need to tell one situation. [music] I need to tell one thing that I'm not using a 2 mm thick thing that I'm not using a 2 mm thick thing that I'm not using a 2 mm thick profile. I'm using actually 3 mm thick profile. I'm using actually 3 mm thick profile. I'm using actually 3 mm thick profile and that allows [music] me to profile and that allows [music] me to profile and that allows [music] me to uh uh uh maintain the whole rigidness of a maintain the whole rigidness of a maintain the whole rigidness of a construction [music] construction [music]

06:18construction [music] and not lose and not lose and not lose stiffness and the transfer function and stiffness and the transfer function and stiffness and the transfer function and everything. And that is actually everything. And that is actually everything. And that is actually important [music] in a way important [music] in a way important [music] in a way because because because if you consider what is transferring if you consider what is transferring if you consider what is transferring sound, sound, sound, that's got to be a material and amount that's got to be a material and amount that's got to be a material and amount of this material. [music] of this material. [music]

06:40of this material. [music] And I started thinking more and more And I started thinking more and more And I started thinking more and more about that because I also got the about that because I also got the about that because I also got the [music] [music] [music] small small small aluminum aluminum plates as the [music] aluminum aluminum plates as the [music] aluminum aluminum plates as the [music] reverb unit. reverb unit. reverb unit. And I bought 0.7 mm [music] And I bought 0.7 mm [music] And I bought 0.7 mm [music] thick uh thick uh thick uh aluminum plate. aluminum plate. aluminum plate. And it was very light and the transfer And it was very light and the transfer

07:02And it was very light and the transfer function was very low. function was very low. function was very low. So it has [music] a very short tail and So it has [music] a very short tail and So it has [music] a very short tail and that immediately gave me an that immediately gave me an that immediately gave me an understanding that uh to have a good [music] transfer to have a good [music] transfer function, we need a mass, good mass and function, we need a mass, good mass and function, we need a mass, good mass and good density. If we want to shorten the good density. If we want to shorten the good density. If we want to shorten the tail, [music] tail, [music]

07:22tail, [music] we just need to think of we just need to think of we just need to think of some more softer materials like aluminum some more softer materials like aluminum some more softer materials like aluminum or copper would definitely transfer or copper would definitely transfer or copper would definitely transfer uh uh uh some transients, but it would not go some transients, but it would not go some transients, but it would not go >> [music] >> [music] >> [music] >> that far and have these massive tails as >> that far and have these massive tails as >> that far and have these massive tails as we have with [music] steel.

07:45As an addition, I got As an addition, I got as you can see [music] slightly here a as you can see [music] slightly here a as you can see [music] slightly here a big collection of different kinds of big collection of different kinds of big collection of different kinds of springs. springs. springs. This is not a spring. This is not a spring. This is not a spring. Different collection of Different collection of Different collection of springos.

08:06And now I can just uh And now I can just uh continue making these uh continue making these uh continue making these uh these units. these units. these units. So, I can build So, I can build So, I can build more. more. more. This setup This setup This setup also allows me to have extensions. also allows me to have extensions. also allows me to have extensions. And I Actually, I have an And I Actually, I have an And I Actually, I have an an example of this extension. I've been an example of this extension. I've been an example of this extension. I've been testing mounting springs in different testing mounting springs in different testing mounting springs in different ways and fashions.

08:35ways and fashions. ways and fashions. I kind of Originally, I was thinking I kind of Originally, I was thinking I kind of Originally, I was thinking about welding the springs to the L-shape about welding the springs to the L-shape about welding the springs to the L-shape profile as well, but I would need to buy profile as well, but I would need to buy profile as well, but I would need to buy steel profile. Kind of want to continue steel profile. Kind of want to continue steel profile. Kind of want to continue building the building the building the modular units, you know, that I can just modular units, you know, that I can just modular units, you know, that I can just use as a uh use as a uh

08:51use as a uh constructor. constructor. constructor. So, So, So, the solution was simple. Pow! Pow! I mean, look at that.

09:09And they ain't going to go nowhere. And they ain't going to go nowhere. If you think that they're going to go If you think that they're going to go If you think that they're going to go somewhere, they ain't going to go somewhere, they ain't going to go somewhere, they ain't going to go nowhere. nowhere. nowhere. And uh actually, I haven't done that. And uh actually, I haven't done that. And uh actually, I haven't done that. So, let's do it now.

09:24Spring bar unit. Spring bar unit. And And And obviously, it's not attached to obviously, it's not attached to obviously, it's not attached to anything. anything. anything. So, it's just this So, it's just this So, it's just this profile with the springs on bolts with profile with the springs on bolts with profile with the springs on bolts with washers. By all the theory, washers. By all the theory, washers. By all the theory, the sound should be loose, short, and the sound should be loose, short, and the sound should be loose, short, and not very interesting.

10:18>> Good collection of those like rolling >> Good collection of those like rolling mechanisms. Wait a second.

10:42>> Okay. >> Okay. Now the wrench.

11:06>> Good. >> Good. Once again, Once again, Once again, the transfer function. the transfer function. the transfer function. I've actually realized that one of my I've actually realized that one of my I've actually realized that one of my favorite test is just to have this favorite test is just to have this favorite test is just to have this this wrench with this wrench with this wrench with rotation option. I mean, once again, the mic is in here. I mean, once again, the mic is in here. We're picking up mainly this one. We're picking up mainly this one. We're picking up mainly this one. >> [clears throat]

11:51>> It's good. >> It's good. So, there you go.

12:09go in here. go in here. >> [music] >> [music] >> [music] >> And what it What would it mean is that >> And what it What would it mean is that >> And what it What would it mean is that we have the same thing now with a we have the same thing now with a we have the same thing now with a reverb.

13:36>> Ooh. >> Ooh. >> [music]

13:42>> I don't care. >> I don't care. That's interesting. That's interesting. That's interesting. >> [music] >> [music] >> [music] >> Should have I used maybe >> Should have I used maybe >> Should have I used maybe Oh. Oh. Oh. Like that? Yes. Like that? Yes. Like that? Yes. So, that [music] is the thing that you So, that [music] is the thing that you So, that [music] is the thing that you would need to would need to would need to pay attention [music] to partly is where pay attention [music] to partly is where pay attention [music] to partly is where the dimensions are going. So, [music] the dimensions are going. So, [music] the dimensions are going. So, [music] regardless regardless

14:04regardless that it's a same unit type of a that it's a same unit type of a that it's a same unit type of a construction, construction, construction, you'd [music] still need to pay you'd [music] still need to pay you'd [music] still need to pay attention to these kind of details. Right? So, Right? So, >> [music] >> [music] >> [music] >> there you go.

14:22Let's make sure that it's Let's make sure that it's uh tight. uh tight. uh tight. >> [music]

14:48>> Good. >> Good. Contact mic on.

15:59>> I mean, do I have to say anything? I >> I mean, do I have to say anything? I think it's freaking awesome.

16:08This is the most simple thing or way I This is the most simple thing or way I could have just imagined that to work. could have just imagined that to work. could have just imagined that to work. And it works just nice. And it works just nice. And it works just nice. It just does. Yes. It just does. Yes. It just does. Yes. Yes.
