Chances that you will keep the "great" sound are slim and none. If you want to keep your sound quality, work with Klipsch to get a replacement driver.

Then you will have two speakers that don't sound as good as the originals. To properly mate new drivers into the system, you will need to redesign the entire crossover network. LSPCad, a calibrated microphone and other assorted hardware are software are required.

That's like saying all cars are interchangable because they have 4 tires. There are dozens of other things you need to look at. The Theile/Small parameters must be the same or you will have to change the enclosure for optimum performance. The frequency response across the passband will have to be the same as well. If your current driver plays up to 5khz without break-up, your new driver will need to as well. The PE specs don't include any graphs of distortion by frequency. That's what you need the measuring tools for.
