never herd a treo but they seem to have a good rep for being a nice sub. as for the hdc they are pretty musical in IMO they keep up with my focals real nice just as good s my old re se's did. both are a good choice. where in Colorado are you? there are a few of us running hdc come to the next show if you haven't decided yet and listen to them.
