If they need to be raised, maybe just move them upstairs. Then raise the roof with them. Hard to say if 5 inch rise will affect the floor boundary response, but Im thinking it may be a nice way to experiment with the room placement. Sure beats rock and rolling relocation. Oh, and you have a great set. Congrates! Must have been fun getting them up there though.

I bought my 9's new in 1980. They always respond to better upstream electronics, better than I could ever feed them. Put the best equipment you can afford in front of them and concentrate on the best room placement. Fretting over the best caps or coil orientation, oriented grain ofc wire and binding posts are unlikely to yield as large a gain in the quality of what we hear from them. These were engineered very well to use parts of the day to a price point. They still compare well to many comparably priced speakers today. 40 years later. I rebuilt the crossovers with good affordable caps and did a refoam on 12's and 8's. reoiled cabinets and resealed well, reclothed the grills without the chrome edges, and didn't try to outguess the engineers that built these. Perhaps my bad, I wish I could give them the room they deserve and all the unbridaled power they can take. But I have maximized the placement and worked on room treatment. By far the most improvement in what I can hear from them, ( although I've lost most of my top octave hearing) these things can still amaze me. And keep me from running down the rabbit hole of constant upgrades in my system. I LOVE the music! These can still move me...
