The room acoustic management is totally different with completely different rules.

Just learning how the speakers interact with the room and seems like less is more with regard to treatment. I have just hooked them up . Lot more fine tuning to come. Will  post pics once done .

I note your choice of The Grail.

A couple of years ago I chose the same after long-term auditions of other competitors in my system.  Grail wasn't the most detailed, nor the most realistic, nor the most anything.  But it has an unbeatable combination of all the necessary attributes.  It just puts across what's on the disc.

Thank you

I started working with room treatment on this room about 3 yrs ago . It has gone through many modifications. Including changes in electronics and speakers.

I have worked closely with Jordan at asc. He and art noxon designed the initial treatment based on basic measurements and parameters, The next test was the Matt test for articulation which we would have run and analyzed over a 100 times over the years . We found articulation defects in particular freq ranges we fixed by working on room treatment and speaker placement. It was easy for them to recommend those changes based on simple physics ie wavelength, distance to wall etc ...no electronics or dsp software involved in tuning room. 

The final tweak was by listening and after 3 yrs now I am happy with balance , sound stage and articulation.  

Yes they do stay all the time.They have specific areas of diffusion and absorption so a little turn messes it up  with usually more absorption that takes the life off the music . 

The attack wall around the speakers help to negate the influence from the balcony , foyer , hallway etc that are outside the room .

Very unusual speaker/treatment. Getting a living space to cooperate with our gear is the biggest challenge.

Does that stuff stay in the room full time? That's a really nice space.
