I don't know much about the Warfdales...but if you want loudest for the buck, you need some Klipsches.
For loudness, you need to look for the sensitivity (measured in dB/1 watt). The horns of Klipsches historically give them some of the loudest and least distortion available.
Other good buys (not necessarily loudest) come from Paradigm and B&W.
Don't skimp on the sub!
