Take a look at Ascend Acoustics. They are mainly known for their bookshelf speakers, but they have an amazing floor standing speaker as well call the Sierra Tower.

I have owned the Ascend CMT-340 mains and center and the CMT-170 rears for many years and they still sound awesome. Do a search for these.
I also love the Salk Songtower speakers. If I upgrade, it will more than like be the Salk speakers.
