Help with room treatment?



I know my set up is very modest compared to some on here but I am just getting into this over the last 4 or 5 months. I built a room specifically for listening and once completed my system has sounded so much worse. Bass is worse, highs are worse. I understand it is a fairly empty room right now. After addressing first reflection points will it get any better?
Or should I return to my living room?

I had a similar experience. Four walls in a dedicated room, empty except for the system, you get all the normal reflections only much more dramatically because of the flat surfaces. None of the usual clutter to break them up.

Watch yourself here. Lotta guys have this unstoppable reflex when giving advice. It goes like this: SPEND MONEY! BUY! PAY!

I’m sure you will see it. If you haven’t already. Like I said its a reflex. No thought. No understanding. No consideration. Reflex. Plain, dumb, mindless reflex.

Simple, easy and FREE test to see if I’m on the right track: clap. Stand different places. Clap. Listen. If the room is really empty and untreated you will hear a sound called flutter echo. Its the sound of the clap as it bounces from side to side and from one end to the other. Related to this, if you play a CD with test tones and move around you will notice places where the tone is really loud, others where it drops way off. Sometimes depending on the frequency these can be anywhere from a few inches to a few feet apart.

Okay so that’s your assignment. Do both if you can but clap matters more than test tone. Get back to me when we know we’re on the same page. Or open your wallet. But I can get you sounding really, really good in a few hours and for like $100, if that. So your call.
Sound absorption panels at reflexion points, behind speakers and behind listening chair will help. Also bass traps in corners behind speakers. Check out ATS Acoustics for DIY products. I made 2x4' panels from their Roxul Rockboard 2", burlap fabric, and 1x3" pine in 6' lengths for frame with cardboard backing.  Six panels could be made very inexpensively. They also have material for building bass traps. I am not affiliated with ATS, just happy customer. 
Thank you! I have 2 fairly good bass traps (foam) in the corners behind speakers, 2/3 up the wall.
Grabbing 20 to 30 1'x1' acoustic panels this week and will see the improvement they make.
Millercarbon I will do that and let you know. Thank you.
Can anyone tell me how to attach pictures to this thread for some better help? 
It's possible my speakers are also misplaced.
