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?

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.
I had chorus 2s for a minute. They would rip your head off without judicious use of EQ at anything approaching loud volumes. I did like them for some old rock and metal(with judicious EQ). They were fast and impactful for sure. Great kick in the gut mid bass! 
@peterjc     please read my lost post.  It is really hard to offer you advice without further input.
