Powerful, smallish floorstanders with high WAF?

If used speakers are an option, I'd recommend the Gemme Audio Tanto or Katana (v2) verisons. Small floorstanders with great sound and high WAF in walnut versions.

These speakers put out an amazing amount of bass for a speaker of any size and are a simple design so there's not much to go wrong. The company has since restructured, and they are no longer made, but that means you can find them on the used market for great prices. (< 2k)

Buy a speaker for best sound not waf man up!!!!!!

What's your definition of smallish?

First thing you have to hear the speakers yourself. What price range are you considering? Check out the Scansonic MB 3.5's. They are about 5" taller but about 2" narrower. Just make sure if you do hear them that are broken in. They don't sound all that great out of the box. After 250-350 hrs you would never think they are the same speakers. Being bottom ported they can be placed close to the walls. They will sound the best if positioned about 9' apart and pointed at your shoulders.
Good luck

Used pair of Totems or Audio Physics fit the bill; they have a number of models at various price points. Side-firing woofs on the AP's dictate careful setup. Cheers,
