I am not an owner of Klipsch speakers, but I’ve heard Cornwalls and Forte models and I like them. But, like any “energetic” speakers like them, they are picky about the amplifier paired to them. My preference would be a low powered tube amp of the highest quality you can afford. Something in the 10-40 watt range should work. Many higher powered tube amps will sound hard with these speakers.
I am not do sure that you can count on carpeting to reduce bass boom. Bass frequencies are not easily absorbed and the carpet might, instead, absorb higher frequencies making the balance even more bass heavy. But, you should be able to find decent balance by experimenting with speaker placement and location of your listening chair.
Good luck.
