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


Help? Certain music makes my ears hurt from my bright sounding Klipsh Forte ii's (Sonny Rollins Saxophone Colossus), Or is it my room full of glass and tile? Or am I listening too loud (80 db), or my 1970's Pioneer receiver? I just ordered some dynamat to put on the rear of the horns. Some music is good though. I have often though about getting another pair of speakers so I can switch back and forth or run all four depending on the music. Any advise?

OP here, Sorry for no reply , been beyond super busy at work, sorry and thanks again to all of you. I ordered some dynaliner for the speakers, and will put that on soon, I toed them in to pass in front of me, out of direct path of my ears, pulled them out a few more inches and surprisingly got more bass, I also knocked the EQ 1k down, that also helped. These fixes were all recommended by this thread. I appreciate it. So, things are at least 50% better if not more, I'm happy enough not deal with the glass or new equipment for now, you guys really helped. thanks again !!!!!! 
get an ashly eq.  knock it down at 2-2.5 thousand.  about 2 db.  fixed.  35 years FOH engineer advice.
Thanks kb7555, I'm using a older pioneer sg9500 EQ, it helps a lot, is that good enough ?
OP here, 1. cranked down 1 & 2 on the EQ as suggested (that helps) and have one speaker lined with the dynaliner, will do the other speaker next weekend. Can't say I hear a lot of diff. from the newly lined speaker.        2. Has anyone heard of china-hifi-audio? They have a Reisong A10 EL34 for $215, I saw somebody on you tube that bought one and said it showed up and was fine? 3. Looking into bass trap / acoustic panels.
