I've build my own loudspeaker driver, now I'd like to get more info on this...

Hi,


loooong time lurker, not so much of a poster, but here it goes…


for the last 2 decades or so I've been building my own cabinets. Always with carefully selected drivers from a couple of vendors during the years.


But never created my own drivers, 'cause I'd Always thought this is way to complicated…
But as I looked at a similar example on a video a couple of weeks ago (it was about a diy coil) I started thinking...


And on a 'good' saturday night (the wife's out with friends, the kids are in bed, dishes are done) I had some spare time on my hands, and tried to see if I could actually wind a coil that I could use in a speaker...

so I ended up with this:


YouTube


and as a first try, I'm quite amazed by the sound of it. It is only fed with a tiny 3w amp set to half...

Now… being triggered by the possibilities of this, I'd like to read up on this and try to make bigger/better drivers myself…

But I have no Idea where to start looking for this..
I'm a software engineer with no EE education, but have gained a bit of knowledge during the years…
But in starting to design this, I don't know the terms to look for.

Was hoping to find so enthousiasts here which just could 'tag' a couple of words on this so I can search for info.

Thanks all!

There have been some impressive driver builds posted here over the years, but I haven't seen on lately. Might be hard to track down.

Of course the guys over in Planars and Exotics are forever building there own drivers.

Sound quite decent 😱, you can try wind your own voice coil.

There are a few examples on youtube showing how to do it using a battery drill.

Hi ghemml, sorry for the late response..


I've wound this coil myself by hand.. .it's a bit above 6 ohm... so pretty amazed by it.

and for those who are interested.. I've built a omni-directional speaker reusing the same coil I had from the first speaker...

(actually, I used the wrong type of glue, tore up the latex from the first one, so instead of rewinding another one, reused the coil and glued it to the sphere)
