Klipsch Forte ii too bright, or is it my room ?

Maybe leave out foam from Beth woofers?

Do you have an REW sweep of the room?

Update,. Hope you guys are still out there, I know it's an old thread now but ...Dynamatted all the horns / woofers. Ok, big job but covered all the glass in the room w/ sheets / blankets, 3 large sliders & windows, covered the large glass dining table, tile 1/2 wall, pictures w/ glass, stainless steel fridge, ovens, some cabs (kit open to L/R), 60" tv & glass fireplace front. And ............. all of you are correct, sounds much better, the shrieking highs are gone. Litmus test was Pink Floyd DSOTM time, and Gershwin, rhapsody in blue. Tried with everything coverd, sound great. Then with just the sliders / windows covered, last with nothing covered. Conclusion: drapes will eliminate 75%+ of the tinny sound. So now will investigate drapes, I saw some on amazon for a very wallet friendly solution. I always likes the dynamics of the Klipsch speakers they just need to be toned down. Nothing quite like them when playing Pink Floyd, Classical, or anything with a sax which I love like Sonny Rollins, not to mention rock. They are not perfect, they lack the lush, richness of some other speakers. But keeping for now. Thanks again everyone! p.s. thanks holmz, they do sound better w/o foam under them.

Ahhh “under”.

I am thinking you meant open cell foam inside of the cabinet!

Listening to my Forte Is as I type this, and I can confirm that Klipsch speakers tend toward brightness.  I can also note that nothing tames Klipsch brightness as well as McIntosh amplification.  Klipsch and McIntosh go together like peanut butter and jelly.  The McIntosh's natural warmth takes the edge off the Fortes, and the Forte's natural brightness keeps the McIntosh sound from getting too warm and soupy.

I have an McIntosh MA6200 for my Fortes, and it works great.  If you hooked yours up to a McIntosh tube amp, you'd have a heck of a system.
