Klipsch have horrible Xover parts all China specials ,how would I know ,
I have been upgrading speakers for 20 years and owned 3 Of Klipsch top Heritage speakers.
you are much better off per $$dollar spent with Spatial audio technologies
they use world class Beyma tweeter,mid driver and powered sub built in ,
land Xover upgrade choices and 4-5:models to choose from Clayton Shaw is a very good guy and engineer .if you call him he will answer any questions and these speakers are excellent midsize open baffle speakers ,with a money back trial period. Just check them out great build, as well as a very defined natural presentation ,not beamy and in your face ,a very Big sweetspot and excellent tight tuneful Bass.
