For All These Years, No Idea I Was Dead

I recently moved and set up my system in a new room which I have been hoping will be good for listening:

very thick, stucco and plaster walls built around 1900
approx 22 ft wide by 26 feet long
and 12 ft ceilings

I was concerned, however, that the room would need some heavy curtains and carpets because:

floor is hardwood on concrete slab
one wall is mostly glass from two huge sliding pocket doors
and end wall behind speakers has two doors, also glass

Itching just to have some music (unpacking can otherwise wait), I set it up before hanging curtains or adding carpet, with only my piano, a couple of pieces of furniture, the stereo and two big sofas. To my shock and surprise -- guess what?

It sounds pretty good!! I am especially surprised that the system does not sound too bright, and I would swear somehow LESS ?! fatiguing than it did in my old apartmenr which I would have thought was a better acoustic environment. Go figure.

I expected this hard floored, glass doored room to sound like a gymnasium but it sounds very ambient and really quite good, albeit with the Typanis pulled out from the rear wall about 7-8 feet, with plenty of room between them and clearance of about 3 feet from each of the side walls.

As I thought about this, I reviewed some threads and noticed that the great guru Albert Porter's room although more asymmetrical, seems similarly reflective in some ways -- what appears to be a hard floor (?) and lots of glass to the side.

So maybe I have been ALL WRONG before with curtains and carpet everywhere, reflective walls only and a more "live end, dead end approach"?

Or have I just adjusted my ears to the difference?

Any thoughts?

Best wishes.
It's always something. Often a room doesn't sound like what you'd expect. With all the clothes and miscellaneous junk lying around my room, you'd think it'd be dead. It's pretty darn lively!
I had a similar experience but changed my mind a bit later. At first, the big room I had (approx 32.3x19.7x12, with hardwood, double wall board, and windows virtually all along one side), sounded very nice. The furniture and area rugs seemed to do the trick. Then I got very heavy curtains (three layers) for the windows -- almost floor to ceiling. The system sounded much better. It was still very alive but more neutral. We recently had the room repainted and even the removal of the heavy valances over the windows made a very noticeable difference! The curtains were still up, but the valances were down and the acoustics were much more "echo-ey" -- I assume that the absorbtion near the junction of wall to ceiling was the cause. Neither my wife nor I could believe it! So keep on experimenting -- you might like it now, but you could love it later with a few more changes. Good luck.

Don't know if you had your Typanis placed like this in your old room, but they love big rooms and lots of space.
