SF Grand Piano Home tweeter upgrade

Kehut. if you happen to do it, please update as I too have SF Grand Home series floorstanding.
Thanks

If you don't mind losing $70 or whatever difference you can't make up, then by all means give it a shot. Just don't drill new holes or make any irreversible changes otherwise as the new tweets will make your speakers virtually impossible to resell. Is this a common mod or have you heard/read of it being done by others? In general I think Elizabeth is right. The manufacturer puts forth a lot of effort to match drivers to the cabinet and crossover design and tweak and tune. This is why I shy away from trying DIY when it comes to speakers.

Hi Kehut,
You can certainly drop another tweeter in, but I would assume that a quality manufacturer like Sonus Faber would put a tweeter pad for the perfect blend as well as impedance and resonance compensation in their crossover network for the tweeter being used. It is highly unlikely that any compensation network would work well with any other model of tweeter, even from the same manufacturer.
It won't damage anything to try... Good Luck, Tim

You're correct Kehut, AG is not really a DIY site. Perhaps you would be better served asking this question on one of those sites.
Pehaps somewhere like here.

I own these speakers for 8 years but would be reluctant to try.
Coherence with the 2 mid bass/mid range drivers is more important in voicing a speaker in my mind.
If the tweeter seems splashy, better resistors (Duelund graphite) and better capacitors (Obbligato gold) in the cross over + clean source, amplifier and better cables will tame the tweeter and smooth it out. It will still be lively and will add air (a good thing and part of the speaker's sound) but will not hiss at you or emphasize sibilance.
My two cents.
