Like most manufacturers the don't like showing you what exciters they mount or how they mount their exciters.
It's Italian, everything has to look beautiful.

It worked for me on my phone,but I need to look on a bigger screen, I keep blinking and miss the exciter.
Doesn't look familiar to me ?

Apologies if this has been covered; I'm still reading through this extremely long thread. If you make your own exciter, could you do away with the spider and just glue the the permanent magnet and the voice coil directly to your panel? Essentially, the panel itself would be the spider. It's understood that you might have to modify/tune the thickness/stiffness of the panel where they are attached.

I have thought this many,many times over the years .
It's just how to implement the way you mount, hang the magnet.
I think you would need some way of re-aligning the magnet in case of sag or warping (large panels) over time.
As I mainly now days use small panels which can hang from the exciter,and spider,the thoughts of spiderless exciters has passed me by.
But spider resonance is a major drawback, as it is connected to the coil area,and if you have watched the chaotic vibrations you will understand why this has obviously been a thorn in the side for standard drive units,and designers.
A coil (or other)freely moving in and out without a spider would be my ideal.
That and the cavity resonance in the coil and panel area.

Thanks Spedge. I understand some of that, though some is over my head. About the mounting, I wonder if you could just mount the magnet rigidly to the frame/wall. Question is if that would dampen some of the chaotic motion DMLs depend on (and annoy your neighbors on the other side of the wall).

Looking closely at the exciter ,it looks like the housing is screwed to the panel but there is some sort of what looks like a foam layer between the panel and exciter ?
But I'm not sure.
The first thing I thought was,is this an exciter or shaker?

If it is a stud wall, then your neighbours will probably have something to listen to on those dark lonely lockdown nights,they may even bang on the wall in time to the music to show their appreciation!
I'm trying not to get side tracked with spiderless exciters ,life is too short,but please ,if you have the will and the way,why not.

I remember when I was going to buy a 'Tube amplifier'.

Makes me wonder about the performance of some other products 🙄

A little older, but shows the exciters used by Opere Sonore

At first I also thought this, but could not find any shakers that look the same. Suspicion now is that they are simply caps over the actual exciters.
I have been thinking about the Dayton exciters. They are 4 ohm and amplifiers in common are designed for 6-8 ohms, like my Yamaha amp. How to think about to put two exciters on a birch ply panel, or two ply panels with one exciter at each (four panels totally) in series to get 8 ohms.
Or the second solution buy a amp who can handle 4 ohms. In this case which amp to buy to a affordable cost?
Do you guys have a good thought/solution?
Thanks!

I think you're right. Possibly wooden. Hence the red 'loctite' to show if anyone has had a little look behind.

The two excites on that panel are different from the other exciter we have seen in the video.
I presume the one at the bottom is the shaker?
The exciter mounting looks different too?
I'm not a fan of exciter casing ,it can cause a lot of noise,as I have found to my cost.
Moldie.
You could be right, the casing could just be cosmetic and change from model to model or just changed over time?
These are obviously being tuned for classical instruments such as piano and violin ,
Would be interesting to hear other types of music on them, but I'm sure this would cause a lot of tut tutting.

I have taken Opere Sonore up on their offer. We will see if anything arrives. It should be interesting reading/marketing 🙄

In the immortal words of Rod Tidwell, "Show me the Spinorama!"
Comparing a speaker to a violin is unhelpful and smells of BS. Driver manufacturers show industry standard spinorama graphs. If a speaker company doesn't want to share a spinorama you've got to ask yourself why. Either their design fundamentally sucks or they don't have confidence in their manufacturing quality control.
Plus, their 'Listening Rooms' are all design studios. Not an audio salon in sight!
Their cube subwoofer looks 'interesting' with its bass reflex port? Wouldn't surprise me if there was a driver, not exciter, inside. They could prove me wrong though. At their prices, I'm not pulling one apart soon. A nice website, lacking much info.

I have been holding off on commenting. My BS meter goes off the charts with some of this companies videos. They have one on Vimeo complete with the owner squeezing trees like lemons, singing, birds and young fawns running in the forest.
They claim these speakers are “instruments” not reproducers which is ahem.... garbage.
I don’t doubt these transducers are good but their presentation is over the top.
Why cover up the exciter? It’s a secret tone enhancing reflector [emoji15]

Hi Dave,
Not having a shot at you, but surely if their transducers were that good their world wide distributors would be recognized audio stores, not design studios.
