Please save me from an expensive mistake! Sonus Faber Amati Futura longevity concerns...

@donquichotte 

The dealer, on the other hand, is far from impartial because it’s him I’m buying the speakers from (it’s a buy back pair).

What's buy back, consignment?

the 4 woofers have just been replaced with new ones by the dealer, not sure why, but they should not be a problem I guess)

That's probably the most expensive replacement out of the way. As for the other parts, I think you're over-thinking it. You could buy the replacement mid-range, tweeter, crossover now and keep them in storage. The crossover would likely last longer than you would care. If you're that concerned, ask the dealer if they could work out a price for it.

@mgrif104 

I wonder if you might consider a previous generation Homage series Amati or Serafino which followed the Futura.

I believe the D.A.D. tweeter started with that generation. That's something I'd consider at loud volume.

@bartsw 

can you elaborate on your comment? Is it that you believe the dampener constrains the ability to play at high volume or that you think it’s beneficial for higher volume?

Best,

@mgrif104 It stabilizes dome vibration to minimize distortion at high volume, which also helps to extend frequency response.

I am not qualified in any exceptional way to answer, but I feel that your worries may haunt you even if nothing happens. I would be wondering why they replaced the woofers and what kind of life they had before going back to the dealer. On the other hand, you may not be like me at all. I once had a Porsche Boxster and because it had a chance of total engine failure, and if it did fail, I would have to pay for it because there’s no dealer coverage or anything, I ended up selling it because all I did is worry if it might fail. I read too much maybe but I just felt like on a teacher salary I could not afford such a thing. Maybe your instincts are right and you should keep looking and see if you can find some sort of giant killer that would work for you. But, if you are definitely in love with this and know that it’s the best thing for you then maybe you should go for it. But do you listen to your inner voice especially if it will not shut up after you buy them. I would hate for it to take your listening experiences because you have to be concerned about the future. And then these days getting any help at all from dealers or manufacturer, seems to be difficult. But again that’s just my two cents and they may not be worth even 2 cents. I appreciate these real world types of posts, because these are concerns that I think many of us struggle with. Good luck! I hope you get Audio bliss in whatever direction you go!

Anything made today will last decades as long as you have ample clean power to not put the drivers into distortion for long periods I own Sonus Faber s and owned 2 before that high build quality .
