Barry_e_cohen:Yes,the Reference 2.I own a modified pair(systempost).The tweeter needs to be moved forward to allow phase alignment.Probably the only flaw in the original,other then the expense of the aluminum spheres and the fact that Gallo didn't support the CDT tweeter.No way to replace damaged units,other than to buy another set of speakers.Hopefully they will support the new CDT for a longer period.If not,the threes will begin stacking up on the side-lines:(
