Just to throw a wrench in the works, I would suggest going with a monitor for the reason that the speaker has to be about 12" from the rear wall.
Using a full sized/full range speaker that close to the wall is going to tend to exaggerate the low frequencies. Most of the speakers you mentioned need to be pulled out into the room anywhere from 18" to as much as 36". The advantage of the monitor is the ability to reinforce the bass while adding the simpler crossover of a speaker with less drivers.
As a rule I am not a big fan of B&W speakers, but I think in your application the Silver Signatures would be something worth looking into, although I'm pretty sure you would have to buy them used.
Another option might be the Wilson Cubs, if you are willing to go with a monitor.
