Speakers good for close to wall placement


There are quite a few speakers I would like to purchase, but I need to be realistic. I will need to find some speakers that perform well when placed close to the rear wall. After that choice I can move on to selecting the proper integrated amp to drive them. Any suggestions on which speakers work well near the rear wall?

Wow, thanks everyone! Lots of new avenues to explore here and exposure to a couple of brands I have never heard of. I’m really leaning toward Raven or Linear Tube for my amp, so efficiency will be a prime consideration. 
In Europe we generally have smaller rooms than in the US so many of our European speakers are designed for close-to-wall placement. One of the best higher end for being up against the wall are the B&W 804D floorstanders.  They are medium sensitivity at 89dB. 
The only speaker truly designed  to go against the wall is the Larsen Speaker
