What speakers work well against a wall

Sonner Audio do very well tight to a wall. 

Audio Note all the way.  I was so impressed with their presentation that I was even considering non-optimal location (i.e. away from wall).  If you can afford it, go for the big ones in their basic model, though the smaller ones also sound good and of course benefit from boundary reinforcement.  Unless you're running something very low powered, stay away from hemp drivers and the HE models.

@scottwsmith - as a general "rule of thumb"  you could use any speaker that has either

1. a completely sealed enclosure
2. a bass port located in the front of the enclosure

Of course this is not definitive, but as a "guideline" it eliminates rear ported enclosures which are designed to have space behind them

Some e speakers with a downwards firing port in the bottom of the cabinet may also a good cabinet.. But this may only be true in some cases - t's a case of listening to them.

I’m also recommending Audio Notes. I run the AN E’s. The ability to run them against the wall is just icing on the cake, not a compromise in any way.  That's part of the reason their presentation is unlike most speakers.  My biggest audio regret is that I didn’t find Audio Notes years ago.

Of course it all depends on your sound preferences and amplification choices. Best of luck.
