OK....I finally get my own dedicated 2ch room.
Dimensions......13' x 20'  by 8' high
It is a room built inside a room...attached single garage, outside shell 2x4 insulated and
drywalled. 2x6 inside wall construction, R 20 batt insul with 5/8" drywall. Insulated subfloor on
concrete. There will be a T-bar ceiling...need the access...but I can put anything in the grid.

I will be running a pair of 60" high Selah arrays and a pair of GR "Venue" Open baffle.

I have never had the opportunity to have a dedicated room before, and so have never
treated a room with Acoustics....in other words I know nothing.....

Since you guys are the experts I thought I'd ask......what would you do?

Thanks for your thoughts.

Piece of advice - take it easy.

Listen first - adjust later.

Do not over do it.

Take care of the clean power delivery.

Your room's dimensions look OK.

Second that.  Speaker placement is a critical component is my two cents.  Looks promising!

Take a picture of the room setup with the speakers as they are. Or alternatively, make a nice clean drawing for us to see. Are the Selah Arrays and GR Research 'Venue' loudspeaker go to be in the same room?

Fully insulate the ceiling before making any judgements.

Yes I will be adding an additional R-20 to the space above the T-bar ceiling.

As far as placement in the room I have now the Arrays and the OBs work well about 8' apart
and listening distance about 8' back. Both sets sit about 5' from back wall....the room I'm building is under construction.....trying to get the sub-floor in the next 10 days.

Yes both speakers will be in the same room....I use the OBs powered servo subs on the Venues
for sub duty on the arrays.

There is a dedicated 20amp line for the equipment, and I have a nice power conditioner in mind.

I should explain....I am a Interior systems mechanic...I have worked with acoustic engineers
on recording studios and radio stations....am currently working with one on a project now.
Making the room itself isnt a problem for me.....I have 30yrs in the industry....its the room treatments I am interested in......and I have talked to my engineer on this.....but he is on a different wave length than audiophiles....more into commercial applications. I figure you guys in
the hobby end would have real world experience with home audio.

Thanks for the info so far....and yes I will go slow....I just need a place to start.

its the room treatments I am interested in

Since you said "I know nothing" my standard blurb follows, which will get you 90 percent of the way there.

All rooms need:

* Broadband (not tuned) bass traps straddling as many corners as you can manage, including the wall-ceiling corners. More bass traps on the rear wall behind helps even further. You simply cannot have too much bass trapping. Real bass trapping, that is - thin foam and thin fiberglass don't work to a low enough frequency.

* Mid/high frequency absorption at the first reflection points on the side walls and ceiling.

* Some additional amount of mid/high absorption and/or diffusion on any large areas of bare parallel surfaces, such as opposing walls or the ceiling if the floor is reflective. Diffusion on the rear wall behind you is also useful in larger rooms.

For the complete story see my Acoustics FAQ.

There's a lot of additional non-sales technical information on my company's web site - articles, videos, test tones and other downloads, and much more.

Thank-you, thats what I've been looking for.

If you aren't too far in, and have the space...

Bigger the better, follow the 1 x 1.61 x 2.62 room dimension ratios, and try to skew opposite walls to eliminate multiple reflections.

My room is of similar proportion to yours.  Having privacy is supreme.  Having isolation from outside noise is cool.  The rest is gravy.

Use lined/insulated flex duct for supply/return ventilation runs and an insulated/weather sealed exterior door.

[PDR]

I had thought of skewing the walls....like on the Cardas site...but I have to be able to
call the area a games room if I ever sell the house...thought the angled walls would be a turn off for potential buyers when I sell the house. I am going to install a dedicated furnace in the room
so ducting isnt a issue ( I live in northern Canada  ). I live in the country so noise isnt an issue...   I can hardly wait.....been wanting my own room for a long time aa

Perry,

I meant all noise from outside the room, not just outside the house.  Think of occupants, appliances, A/V equipment, wind, rain, etc.

Check building codes for furnace installations.  As most listening rooms are sealed to keep noise out, there probably wouldn't be sufficient venting to allow the furnace to work.  And if it did work there could be dangerous build up of carbon monoxide.  Besides, furnace burners/fans make noise, so it'd be best (acoustically) for it to be outside the room anyway.
