Seek non-ported speakers - $700 to $1500 To stop the port-itis in my room!

I have a smallish room 12x12 that has an unusual ceiling.  I've used several highly regarded speakers in the space and the real ported ones are the biggest problem.  I tried KEF ls50's and wanted to love them but the lower-end was too puffy sounding.  Front ported speakers do have less of a "port-itis" issue.  I found a used pair of polk lsi9's and they sound very good in my room but not great.  I'm looking for ideas for non-ported or ported speakers that are less problematic.  Range $700-$1500.  Thanks for your input audio brothers!  Drumbe the retired drummer.
