The Focal ISU200 is a common upgrade, although I had already installed the Hertz set I wanted to evaluate the Focal.
2 Hour impressions, it's definitely better than stock, but not as clean, low or dynamic as the Hertz.
RWD/SR+ and you don't want to install a sub, the Hertz will give you a bit more
RWD/SR+/Premium and you have a stock/aftermarket sub, I'd probably go with the Focal and save a few bucks, once blended with the sub the output is still nice. (that being said I have a RWD with aftermarket sub and I will likely switch back to the Hertz, but needs a few weeks to give a proper evaluation with a more diverse array of music).
I still have to design brackets for the Focal tweeters so the Hertz are still installed.
