Room treatment with acoustic panels

My main room is 45 by 30 or so with 20’ ceilings (canted in on the top), large stone fireplace on the long wall with some french like windows floor to ceiling on the other wall, a loft on one end with my hifi rig under it on the "short" wall (more tall "french" windows). Horn speakers (with a couple of REL subs helping out) with my earballs maybe 9’ from them. Furniture, book cases, CD racks, artwork, electric guitars on the wall (acoustics protected in their cases) vinyl in a tall rack, blah blah. When we moved here a few years ago I thought the room would echo and just be a mess. It’s not. I guess it sounds like a room of some sort but music sounds great all over it...even in the loft. Tube or SS Class A amps, and astonishingly resolving sound free of "room treatment" or DSP or anything but engaging my Loki Max from time to time. I vary the level of my subs. Under the loft with the rig the bass can be extreme but that’s not my serious listening zone, and it’s better for dancing anyway. No "treatment" for me except cleaning the wax outta my ears. Does that count?

I think people Skip setting up the room acoustics correctly because they don’t really know how to listen but then they wonder later why the base sounds booming or the highs are accentuated or things like that

I am trying to get a consultation with GIK. They have an online form that you can fill out, attach floor plans, photos, etc. But, when you hit SUBMIT, nothing happens. Has anyone else had this problem?

The first thing to evaluate before you get traps, before you undertake any kind of room treatment is the response of the room measured at your listening position.

The spectrum that REW creates will graphically inform you of the room modal frequencies and the room's response at your listening position.

Number and placement of traps should be guided by the frequency spectrum as it responds to placement of traps.

Corner traps are a necessity. GIK makes acceptable ones. But the traps from "Real Traps" are made better (no veneer over particle board) and perform better. Real Traps prices are competitive. 

Also, the Real Traps website is chock full of technical advice, including third party measurements of the performance of their traps. Does GIK provide the same?

This is always a fascinating topic. While at the School of Architecture at the University of Toronto, I was fascinated by Roy Thompson Hall that was designed by a legendary Canadian architect Arthur Erickson. This marvelous conceet hall is home to the Toronto Symphony. I didn't know very much about acoustics back then but I was nevertheless intrigued by its design, so much so that I visited a few concert halls across European cities.

My music room is in one is my refurbished barns in the countryside.  It's not acoustically designed by any means but it's a peaceful space where I relax and listen to music namely jazz, jazz trios, classical and acoustic guitar/ambiance music. I created diffusers using wood elements that actually define the room but whether they work acoustically or not I couldn't tell you.  I do have plans to install 4 ceiling clouds and an artistic 3D wooden panel on the front wall as a diffuser but given the design and esthetics of my room I can't or rather don't want to do more than this. I've rendered my room as it exists with the very ceiling clouds and 3D wooden panel that I'm be purchasing in the fall.  I guess I'll know then if these clouds actually do anything.  BTW, these clouds will be 1/2" thick felt hollow boxes filled with 6" thick Rockwool Safe and Sound acoustic insulation and will be suspended 4" from the ceiling. You can see the rendered clouds in my profile.  Again, great topic!
