Most important fundamentals in your built/modded listening room?


Situation: We will be doing a basement renovation soon. At the moment, I don't have a full go-ahead to turn this room into a listening room. The room will be multipurpose for another 4 years (when the last kid goes to college). I am not working with $100k and an architect. This is about laying the groundwork for later adjustments.

Room:
  • The room is a rectangle: 27 ft. x 17 ft. x 8 or 9 ft.
  • (I say 8 or 9 foot ceilings because right now the rafters come down to 8 feet but the floor above is at 9 feet.)
  • Walls are unfinished, the ceiling is unfinished.
  • Two outside walls are concrete.
  • The floor is concrete.

There's a lot of literature out there, including a great article by Harley about building a listening room. https://www.theabsolutesound.com/articles/building-a-listening-room

But for now, as I said, I'm looking for ways I can PRE-PLAN fundamental elements of the room so that later it can be tweaked even further.

QUESTION: What would you suggest should be done that is fundamental to the build out of the space?
  • Wall construction?
  • Dimension modification (cannot make ceilings higher)
  • Electrical?
  • Other things?
Thanks in advance for your tips!

I had multiple goals.  I have a 50/100 Hz resonance in the room that needed treatment so I added GIK's 7" thick bass traps with diffusion panels on top. You don't have to go that thick, unless you lack where to put bass traps, but the GIK Impression panels are very effective and very affordable compared to the prices I have seen on some QRD types.
So one thing I just discovered is the joy of diffusion.

I've heard well balanced rooms before, with a mix, but only recently have I been able to do A/B comparisons with and without them. 

If anything, incorporate diffusion into your planning as soon as you can.  They add air and shimmer without glare.
