Hi guys,
Was directed here by another forum member.
I'm looking to modify and improve my existing two channel music only system in the bedroom. I've tried a bunch of speakers in this setup and most seem to come out very bright and tiring for the ears. We don't have any treatment on the walls. On the attached schematic ( forgive my poor rendition), the right wall has curtains. Other than that the walls are bare. I like to listen to the system, with me on the bed, my head close to the back wall. On the drawing, the speakers are indicated by two small circles, drawn next to the dresser.
I would appreciate any help. I have never done any formal acoustic room treatments, and my knowledge is very limited. I like to do this work over the next few months and if possible would like to keep the budget under $1500.
Thank you in advance and feel free to ask me questions and clarifications.

Perhaps you're getting reflections off the headboard? There are few things worse than a hard surface behind you. And the closer it is, the worse it is. Cover it up with something. Stack up pillows, or throw a heavy wool blanket over it. If it's just the wall behind you, get some sound traps. www.realtraps.com

Maybe go the cheapo way and attempt to turn down the trebles?

Are the speakers ported or sealed if they are ported, put some 2" panels behind them. Are they floor speakers or bookshelf speaker? If you have towers that extend to the lower frequecies then some front corner basstraps is also a good idea. Then walk around the room at ear height with a mirror any location on the side walls were you see the tweeters in the mirror mark that spot. Put the panels there. Right directly above the listening location put some 2" panels on the ceiling too. DO NOT USE AURALEX foam products. Foam isn't very good. http://www.gikacoustics.com/ http://www.atsacoustics.com/

No treble control on my amp.

There are some pillows already, but the wife wont allow me to put a blanket on the headboard. The headboard is not huge but is considerable. Its not continuous, more like a lattice pattern.

Temporarily place the speakers near the foot of the bed and closer together while listening from the center of the bed. This will lengthen the path of the reflected sound and shorten the path of the direct sound.
While I'm sure that your wife won't like the idea of crawling over the bed to get across the room, it could present her with a contrasting solution. :D
If getting you and your speakers away from reflective surfaces didn't help, then I'd look at the electronics for some kind of malfunction or setup error. If everything's proper, then you could try using an equalizer to tame the brightness. The EQ should be the easiest thing to get wife-approved (unless, of course, you go for a pricey room correction system).
