Had Three Different Speaker Thoughts; Now A Fourth


I currently have B&W 606 S2 bookshelves and I am thinking about doing something different, I haven't been overwhelmed by their build or performance. So I read and read and read some more and I think I have it narrowed down to three choices. Auditioning any of them is highly unlikely.

I've looked at the Tannoy Eaton, the Volti Razz and the Magnepan 1.7.

My listening room is 12x25 and there's not a lot of room for moving my LP (odd closet and a center of house chimney). 
I have a Parasound Halo6 Integragrated. 
Given the size of the room would the Razz be too much? This is my top choice.

The fourth option a friend mentioned and it has appeal is this... I also own a pair of Polk RTiA7 towers. They are a really nice cabinet with a nice build that house a 6.5 and two 7 inch drivers and a tweeter. He said I should think about replacing the drivers with Scan Speaks and upgrading the crossovers.

Thoughts?

I would go for the volti it will not be too much for your room because a large speaker loafing along is better than a small one straining to fill the space.

Possibly the most over hyped speaker ever, 
Bose being #1 snakeoil-ed. 
B&W a  close 2nd place.
Is that company still in business? 
Hard to imagine those things  continue to sell.
The used market is flooded with B&W's. 
Looking at this from a different, more elementary angle, you should strongly consider the width of your room.  You say it's 12' wide, so unless you absolutely hug the walls with your loudspeakers, and the best people do not, the width of your speaker choice definitely matters.  If you hold them just 12" from your sidewalls, and they're over 20" wide, like the Tannoy and the Mangepan, they're going to be about 6' apart.  For me, that's not enough.  A tower that is 8" - 10" wide is probably a better option.  The Volti Razz is 15" wide, the slimmest of your first three choices.
