Drdna - do you already have your Titan's set up? If so, what specifically do you want to improve? Using two or three amps still requires some type of crossover. So this will not "eliminate the colorations involved with the passive crossover network." I agree that crossover components are very audible, but so are amplifiers. If you haven't already done so, suggest that you first set-up your Titans per Edgar's recommended configuration. Live with it for awhile, then decide what to do next.
