Justin, your old Klipsch are significantly more sensitive than the M100s. The spec sheet says so but so do my ears because I've spent some time with Klipsch speakers in the past. This means they go loud with relatively little power - and ultmately reach louder than the M100 if the Klipsch spec is accurate at 600W peak power which I assume is before compression sets in. This is largely a result of the tractrix horn. Unfortunately, this horn also makes them unlistenable.
I really don't want to influence you too much regarding the M100s. I'd love to hear your thoughts on the listening experience.
One other thing, dude. 95 to 100dB is dangerous for your ears. It's actually louder than what your phone app is reporting because the mic is dynamically limited and so is the frequency response.
