, & he (& other statues & figures I've had on them over the years) do just fine. I did just switch him out for the new Vader PF, & just as with the others, he's doing just fine also. The speakers I WOULDN'T put him , or other figures, on are the subwoofers. Those babies are literally bucking broncos, & will throw everything off of them while they rearrange your rib cage 
I've had mine on top of my front channel Pioneers (they have 10in woofers, they're not small speakers). I have a 750wt 7.2 surround sound system, & I don't listen to movies or music quietly
Hell yes! Very nice. That's what I like to hear. And sounds like a killer setup man. 
I have 7.1 with all Infinity speakers and 12" sub. Sub shakes the house as it is, can't imagine a second!
Fett will be going on a floor standing speaker in the front, no worries there. My only worry is if the base will be hanging off a bit. If it is, I'll have to rethink my placement.
& yes, with 2 subs going (one 12" Polk + one 10" Polk), I do have to re-level all the photos after some movies (Mad Max). I've been building my set up for years, getting what I can afford at the time. So my system is kinda hodgepodge. The Pioneers were the 1st purchase over 20 years ago. They're floor standing, but I have them on pedestals. They're 13" deep x 14" wide, so they're perfect for displaying beautiful pieces of art. Your Fett, if he fits on the Infinities, will stand out beautifully (as he should). I've got my Vader PF on one, & eFX Vader Limited (on a different stand - not the eFX stand) with his ANH lightsaber from TCSS in front, on the other.
Infinity, NIIIICE!! I think those are gorgeous speakers! Sounds like you've got a pumping system as well
I am working on changing out my hodgepodge speakers to all Polk Audio, & I'm looking at new floor standing front channels next. But the narrower foot print is the only thing giving me pause.
