TSx-compatible center speaker options for narrow space
Hello, I'm interested in upgrading my 5.1 system with the TSx330T but I don't have space for the matching center speaker TSx250C or even TSx150C. 
My TV stand has openings only 17" 11/16 wide.
I'm concerned the speaker would not support my 100 lbs projection TV.
I also worry that the sounds would not be good if I push back the center speaker behind the TV stand's front beams.
Any suggestion of a smaller compatible center speaker I could use?
Or some other creative arrangement?
Thanks!
