Powerful, smallish floorstanders with high WAF?

Salk Sound has a terrific small speakers.  For instance: http://www.salksound.com/wow1%20-%20home.htm or

I was one of those SMAC members looking for a subwoofer.  
Also, SoundSmith has a great set of small speakers I was totally impressed with!  Either the Dragonfly : http://www.sound-smith.com/speakers/dragonfly-stand-mount-speakers

Or the Monarch: http://www.sound-smith.com/speakers/monarch-bookshelf-speakers

Thanks for all the great tips, guys.  Really helpful.

I second the Gemme Audio suggestion. I own a pair of Tantos. They are small, beautifully made, and produce the most incredible bass I've ever heard without the use of a sub. 

I have Focal Diablo Utopia III's and they have huge WAF and they sound great.  So everybody's happy! :)

I’ve owned many small floor-standers over the years, and WAF is always paramount in our smallish 1932 San Diego home. I would highly recommend Neat Acoustics’s Motive SX2. This phenomenal 30" tall 2 way delivers deep, articulate bass that is astonishing for their size. They’re dynamic, musical, tonally accurate, expansive, heavy on the FUN factor, and in the hi-fi realm, relatively affordable. Try to track down a dealer you can audition them at, then try not to fall for them.. Good luck!
