"Really it's outboard active configuration that's the optional approach here, as passive configuration and typically only using a single amp has been the only route so far, and thus by all accounts will be the default and most common way to configure these new Klipsch models looking ahead - that is, certainly until people begin to experience or otherwise learn about the traits of active config., at which point it's likely to be more widely implemented.
Few seem to realize that the more predominant signal degradation lies in the passive crossover network in the midst of the amp-speaker interface and not a quality DSP unit prior to amplification, which negates the passive crossover components on the output side of the amp and keeps them from meddling with its control over the drivers. Not to mention the benefit of amp load independency of the different driver segments that sees each their dedicated amp section handling them exclusively, in addition to the advantages of being able to apply differentiated delays, etc."
Interestingly, there is nothing new here and any well-seasoned hobbyist is well aware of the multitude of approaches to sound reproduction and accepts them as revelatory or rejects them out right. We've seen this over and over again at least as long as I've been around. You should have a look at @norcalal's post preceding this one.
