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

I hav3 owned. All but the Khorn and even with the best effort 
the Xover by far is the weakest link then connectors ,on series 4 
I believe they upgraded the wiring but the Xover parts inside 
are on par with Magnepan -Rubbish which I hav owned them also.I have been upgraded Xovers since 2k. Not even average in Anything IMO ,there’s your weak link 
upgrade to a much higher quality Xover cap to start
, I see it all to often even in$15-$20k speakers like Magico, and Marten , for example Mundorf
is good, the Supreme is their best Black color caps,the white Evo 
is a little better then average the white Evo silver gold oil capacitors this is what these $20kspeakers are using ,Why ? to save $$ .The cornwalls would be very-well suited with these capacitors That are a pretty decent and a good fit ,start with that and maybe Mundorfs Supreme resistors ,a substantial Sonic upgrade. The best capacitor setup I have found even vs the $$ 
Duelund cast capacitors is the excellent Jupiter Copperfoil caps 
with added 3% of the main capacitors value as a bypass cap the best out there VH audio CUTF bypass caps  you get the tone and depth as well as pristine topend I just incorporated this in a dac for a friend and preamp this applies to the tweeter, midrange not bass but a bit $$ 
we just did a Magico A5 which was made a very-good speaker 
exceptional , path audio resistors are the RR of resistors at $26 each $$ but great . Just go to Humble homemade hifi capacitor test, Tony has been doing cap reviews for 2 decades and pretty accurate . Vhaudio  does not donate free caps for reviews but very well know to DIY and techs  , I do  use the Vh Odam caps which are very good  on some builds ,more neutral but very detailed  depending on the system and speakers ,nothing is 
a perfect match Synergy is key 🔑.

@audioman58 Way too much info for this thread, OP looking for simple fixes. I happen to agree with you, my Klipschorn, extreme mods.
I saw OP later post. He has idea of fixing room first, this is exactly how he should proceed. He then mentioned amp or new speaker next, Either could be best move for him.

@sns 

 I'm surprised you can make heads or tails of his posts. That's some tough reading right there...

1. Every speaker I have ever owned has benefited from room treatment. If what you're describing is accurate, (room) you won't be totally happy with any speaker until you take care of the room.
2. Those old Pioneers Receivers are grainy and miserable sounding... get rid of it!
3. Klipsch speakers done right, in the right room can be transforming! You might need to spend some time and money with crossovers, a little damping, tube amps, interconnects, etc.
