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 .

I am always rotating power amps through my Lascalas. My Yamaha pro amps have a red led indicator per channel that show when 1/2 watt has been reached, and it is plenty loud for me. At the level the OP is listening, there are many areas of the Lascalas that are ringing and vibrating that should be reduced by dampening. The shoutiness and harshness spoken about is caused by THIS, and not the drivers. Dynamat should be used on the metal mid horns immediately. The Klipsch forum has much information on the subject. Enjoy ! MrD.

As I stated in my earlier post, back in 1970, Klipsch used metal mid horns, which, at a louder volume, would ring and resonate. I believe this is what you are responding to. I suggest Dynamat, or another type of damping material, to dampen the outside of the horn. The bracket holding the midhorn ( near the driver ) to the doghouse, and it’s surrounding area, are also very resonant, especially at a louder volume, and should be damped..
