Powerful, smallish floorstanders with high WAF?

I've heard the Larsen loudspeakers and agree that they have a high WAF.  They are designed to be furniture first and audio gear second.  They have a very 2 dimensional image and cost far more than I think they're worth.   Mostly sold to people with money who "want the best" because can afford it, but also want it to look like furniture.  Goes well with your McIntosh stack.

Not sure if they're still available, but there was a pair of Joseph Audio Pearls for sale here that are not too big, very nice looking, and will sound substantially more muscular.  If not their Perspective speaker would also be worth a hard look.  Best of luck. 

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.
