Hard to keep your hobbies going when you are being invaded.
You might find this video of interest, I sure did.

In three years I partially restored the workshop.
And here is a new work, according to the theme. One I did myself.
And the other was made by a follower.
He did not extend the coil with a paper ring. He made new coils of precisely the required length

When we say the coil, we usually refer to the copper part only. The part the coil wraps around is called the former (it gives the coil it's form).
When you say he made new coils for the new length, it sounds like you are saying the copper coil reaches all the way to the cone. It's more accurate to say the coil is the same but the coil former extends fully to the cone (honeycomb).

Perhaps I was unclear.
Usually the term "coil" refers to the entire voice coil. Winding with frame.
A product manufactured in one cycle

By the way, I use the amplification of the magnetic system of the speaker. By combining two well-known technical solutions.
A ferrite magnet for repulsion on the back of the main kiltsevogo ferrite magnet.
And a neodymium round magnet on the core.
Also for repulsion.
The combination of these solutions into one gives a greater effect than the sum of the effects alone.
Perhaps this topic deserves to be highlighted separately. If they are not already on the forum.

Hello Svyatoslav, such a magnetic system should increase the efficiency of the electric motor, that is, increase the sensitivity, have you made measurements in comparison with one magnet?
This thread is really interesting. I must've missed it when you first posted. Great work!
I can see me trying this one day.

Congratulations!
Yes, there are measurements, but so far only on the side factor. Unfortunately, I don’t have a teslameter yet.
From the influence of two countermagnets, Qts decreases by about 40%.
Our colleague from Odessa reported that a neodymium pill on the core increases the induction in the magnetic gap by 0.15...0.25 T.
This is very good, and it is done simply.
Later I will open a corresponding topic.
If it is allowed, there is such a topic of mine on another resource.
