Hi i promise last one and depending on the answer i will move away 🙂
if the more critical applications for vibrations/resonances control is the bass reproduction would it be wise to follow the design and construction principles for a subwoofer cabinet also for a full range speaker box ? 🤔
if so the next issue would be to spot the best executions If so i will start to read about subwoofers
I was looking to a Rel subs ...
Still it has been very well reviewed

not a big deal to me And most of its weight should come from the driver and the amplifier on-board
Still it has been very well reviewed
Until the baffle gets large WRT the driver, the driver sufficiently stiffens the baffle and even more so if a 'U' brace clamp or other form of mass loading the driver to it is used.
Just correcting/clarifying what I said in the second sentence of the last post... It's easy to assume, but it isn't always the worst problem. Sometimes tests ignore the point I mentioned in the first sentence.
Still, as GM adds it is a good thing to tie the walls together. I'm suggesting it is also good to watch the driver mounting and to use CLD.

It is not the air inside the box that spreads vibrations. It is the vibration of the element that is transferred to the front that is the problem?
Does the problem decrease if you have a small front?

Thanks. If I understand correctly, it is the vibrations of the basket that mostly affect the result?
I have seen your construction with supporting the basket inside the box.
That should reduce the vibrations to the front.

Is it possible to reduce the vibrations of the basket by reinforcing it?
Have seen some picture where the basket was coated with modeling clay. I think it was a metal basket.

That's damping for the 'ringing' of cheaply constructed drivers. You want to reinforce a cheap basket, then epoxy steel rods to the frame legs and a circular steel plate on the backside of the flange and tap it for driver machine screw hardware mounting, though personally used any this bad for skeet practice. 😉
It appears that the resonances spread from the basket and can become self-oscillating. Especially in a molded basket.
A plastic basket is better for that purpose. It creates smaller resonators. So some advantage of plastic basket exists.
FYI/FWIW, etc., the two molded plastic baskets I've been exposed to flexed enough to bind the VC in the gap, burning them up PDQ.
As you say, there are different ways to avoid this. In any case if you are talking about a high Q resonance, damping is one of those ways.
No argument from me when it comes to foreign made drivers, but then I've mostly dealt with American made cinema/prosound drivers built to 'take a lick'n and keep on tick'n' 😉, though their later consumer products (partially built) I was exposed to didn't require any damping/reinforcing either, though like any speaker assembly it will benefit from mass loading, i.e. make it one with the cab or completely isolate it from the box like the pioneers originally did.
