Folded tweeters vs. dome?


Good day, I am searching for main speakers which will replace my Kef IQ5's.  I want them to be a step up in soundstage and transparency, but only have a $1200 budget (family man you understand).  I have a Klipsch 12" sub so the deepest bass is not an issue.  My question is, in the opinions of those posting here, which tweeters will serve my purpose best, folded or dome?  I see a lot of speakers in the price range I'm searching, both 2.5 and 3-way but have not been able to audition any as of yet.  I'm watching used sets of Golden Ear Triton 7's, Wharfedale PI-40's, Quad Classic 23L among others.  My listening is a mixture of music and theater, most genre's.  I have a Marantz AV7005 pre/pro, a Rotel RKB 650 bi-amping the mains and (Kef) center, with a Rotel-RMB 1565 driving the surrounds (B&W and Klipsch). Thanks in advance for your input, so many questions, so little space.

I do like the Kef sound, and as the new Rotel burns in the IQ5's are sounding better and better.  I enjoy it loud now and then, but usually at a moderate volume, IMO.
Eric, the living room has the usual accouterments, the speakers sit about 2' off the back wall and in front of the entertainment center by about 4". There is a blanket chest in front of the sofa between me and the speakers, but low enough that I don't feel it's messing up any imaging. (I can see the bottom of the speakers and 8' of carpeted floor in front of them.)  The speakers are a good 9 or 10' from the sidewalls.
I’d try to listen to some Paradigm Prestige 15bs.
they are highly resolving, balanced and will certainly disappear!
I see The Music Room has some Martin Logan Aerius i's in my range.  Thoughts on the electrostatic?
When I started building my system I auditioned 5 pairs of speakers and picked the Triton 7's...they were outstanding and easily sounded better than anything else I listened to in the price range.  They were great for jazz and chamber music but once I started listening to rock and classical there wasn't enough bass and I didn't want to get a sub so I traded them in for a pair of Triton 1's.  BTW....my dealer in Champaign IL offers 100% trade in credit if you purchase a pair of speakers that are at least 2 x your initial purchase within 12 months.  His price for a new pair of T7's is $1400.  Hope this helps.
I must say the the GE T7's have definitely got my attention.  I fear that a bookshelf/stand mount just won't quite fill the bill as mains in a room as big as I have.
