Hi Louis:
What are the differences between the TS-2 and the Super 3; other than the obvious difference in driver size?  I would be using either model on its side (horizontally, like a center channel speaker) on shelves inside of a closed back bookcase.  I had used the Super 3's (narrow cabinet) this way for a few years with a Prima Luna tube amplifier and enjoyed the speakers for the most part, but they could be a bit "honky" on occasion.
The burl ask finish looks absolutely incredible.  
Many thanks, 
Rich
