Hi there everyone, long time no talk!
I recently moved and have my listening setup in the large, open basement. It is nice because I can listen as loud as I want, only problem is I am noticing some harsh brightness from my system. It is fatiguing after a good 45 minutes of listening. I feel like the highs are a bit shrill, and the bass isn't as deep and punchy anymore. The ceiling is open joist spaces, walls do not have drywall but have insulation and studs, floor is concrete, windows have no curtains and are near the top of the walls in my basement. Dimensions are approx. 25 feet wide by 20 feet long by 9 foot ceilings.
Also, Anthem came out with a new updated version of ARC - Anthem Room Correction software. It is incredible what it can do. I have ran the calibration with my current room setup. Haven't had much time to play around with it more, but there are tons of options you can change with it now. (Red lines on ARC graph show my measured results, black line is target, green line is where it corrected it to. The ARC helped a lot, but there is only so much it can do with bad room acoustics. I can will attach the graph along with the room layout.
I made a pretty detailed drawing of my current situation, I was wondering if you fine people could please help me with suggestions as to help make my room sound better. Only thing I have done so far is add an area rug, hang the 2 homemade 2x4 acoustic panels that have Safe n' Sound stuffed inside, (I have 2 more I am making). Would putting panels on the front wall behind the speakers do anything since the back wall is so far away? The chair is a leather office chair, would putting a pillow behind my head help? Would making this area into a room with a back and left wall help or make it worse? Would it help if I drywalled the basement?
I would greatly appreciate the help and input! Thx <3
