Hello, guys! If anyone's willing to share his own wisdom and know-how, I'm wondering how do you make layer-y almost 3D-like textures when making acrylic shells/faceplates? Like when you pour a shampoo in your hand, that kind.

Something like these?

 

[Giru]

Yeah, I mean something like this. So it's not possible to do this at home?

This can be done. You'll need to first make the shells and then create a slot (about 5mm or more) deep in the faceplate region.
Getting the layer design is pretty straightforward (glitter paint + self cure epoxy). Pour it into the slot you've created and let it set. Make sure to leave an mm or two for another layer of clear epoxy from the top. Let it set. Sand and polish.
Hope this helps

So here is a kicker for you

Sonion 2389D internal series x 2 parallel + 100ohms resistor + custom zobel if you need one

Order is
Drivers - resistor - zobel

The inductance after resistance would be 8.58308604mH

Zobel is

0.5113106365000213 uF
129.5625 ohms

Try to keep it near value


2 tubes
2mm ID
8mm lenght
Green damper at end for both


Here is diffuse feild with top end spec and distortion
I mean it might kill planar

As you have divided the volt and ampere by 1/2

1/2 volt and 1/2 ampere per driver or true 1/4 power split.

All the drivers will play 1/4 of its loudness and will combine up to make the SPL.. this will reduce distortion by huge margin

You can experiment to red damper if you want for more smooth playback

Would that be the correct way to go???
Do you know impedance?? Would be hard to drive ?!

The wiring diagram always get over my brain
Wait

I will draw it for you in some time(tommorow max)

Slightly busy with some work

Just make 2389 in parallel and then put the 2389D in series

This wiring never goes wrong

I'll give it a go! Thanks a lot!

You mean like these?? The three that are not yellow are Kirinite. The yellow one, I bought from eBay. Do a search for knife scales, you'll find all kinds of cool swirled acrylic stuff. I've tried making my own, so far with no success.

Quick question...I assume you purchased thicker blanks and worked them to thickness? I ask is because all I see is knife blanks, pen blanks, etc and all have to be either sanded or cut to thickness. Do you band saw, sand, or do you have another method? Any tips appreciated as I have thicker blanks and heave not worked thm yet...

 

[Bassiklee]

The yellow ones were 1/4" thick. I attach them to the monitors, then grind them down on a belt sander. The Kirinite I buy in 1/8" thick sheets, and cut it down into blanks on a bandsaw.

I suspected as much. Do you then use one of the buffing compounds or do you go the Lac3 route to get a finished product...or a combination of both?

 

[Bassiklee]

Lak, but I don't use Dreve. It yellows too much for my liking. I've been having good luck with Pro3dure, and I'm about to try some Surehold. The last batch that went out were sprayed. I stole that idea from Jerry Harvey.

Did you try the ratio with the thinner or pure lacquer?

Lemme know how Surehold goes. Been eyeing on them.

 

[Bassiklee]

Haven't thinned any of them. Will do, re: Surehold

 

[Bassiklee]

That's not one of mine, but it's a good example of what a sprayed lak shell looks like. It's a different finish from what a brushed or dipped finish is.

Just Did a 2 driver Universal and Wanted to share results!! Didnt know that a 2 way could sound that smooth!!! On some Songs thou a bit sibilant!?there is a notch a 3,4khz!

Recipe
22955 with 10ohm series, 14mm 2ID, red damper close to spout
29689 3,6uf in Series, Zobel 10ohm/20uf, 8mm 2ID White damper end of tube

Thanks for the Zobel as described by @dhruvmeena96

Have a Nice sunday!!

Hmmm weird. Here's mine. Smoother finish than brushing.
