How much power can a pair of Klipsch La Scalas take ?


I have two emotiva 2gen 2 amps and I was wondering if I can safely run my La Scalas on them. They rate the speakers at 100-400 Watts at 8 ohms.  My amps are 250 rms at 8ohms. And 500 at 4 ohms. I’ve herd Klipsch speakers act more like 4ohm speakers than 8. I up graded the crossover birds and horn tweeters from bob Crites and they sound amazing. So I don’t want to hurt them .

A-I've seen clubs use LaScalas.  They can put out a ton of sound without too much power.
B-It's not the wattage that will blow a speaker, it's the distortion.  Your ears will bleed before those will blow.
C-I ran my Cornwalls with 100 watt Threshold and never pushed the power output.  10 watts was fairly loud.
I ran mine with 35wpc tube amp. They were more than loud at 12 o clock. I also ran a 135wpc vintage marantz and they handled it no problem. If ran too loud your ears will bleed. 
I’m trying a acurus ss amp. I’m having trouble with the midrange if the song has a lot of mids in it they get fuzzy . Any ideas on what it could be or how to fix?
i have already upgraded the tweeter and crossover boards with bob Crites .
Keep the.peak SPL's below 100db! Above that all the older Klipsch speakers begin to sound shouty and harsh! Lesson learned the hard way!
Shoutiness and harshness are inherent in those drivers when pushed above 100db! Fooling around with the x-overs will not remedy this!
