Well I have got down to business with some room tweaking for the CLS . They are a bit more picky with the stone fire place and the room itself. The temporary stands have alowed me to final tweak while I put this all together . I am in the process of finalizing 2 different designs. Both are metal, more on that later.
I could not get what I liked from just the room alone. So I went about doing what I do best . DIY mods.
After reading a lot on this site and a few other sites I decided I would make a few panels. At first I tried some small temp ones and a few blankets , a few small wads of foam and any other thing I could get that was somewhat available. (real high dollar acoustics stuff).
What I assumed to be true was that the center fireplace was a disaster for image. The upper corners and the lower corners being set back about a foot from the fire place were areas of concern to. I basically had two alcoves 1 foot by 3.5 foot deeper than the actual front fireplace wall. it wasn't a disaster but it had potential for concern.
I built a 97 inch x 4 foot panel for the center out of 3/4 MDF wrapped with 3/8 Acoustistuff batting. The out side is wrapped in a red Diamond textured cotton knit. It fits flush under my mantel, and is verticle, acting as a real wall. I was not looking for a BASS blocker but rather a flat wall with good reflection and a bit of deadening as I still have the upper stone wall that has diffusion. The corners again were merely 3/4 mdf ripped on a 45* covered with the same batting and the same knit material.
I was looking to tame some of the echo and get a solid deep image with out loosing any bass or midrange that the CLS is famous for.
I do not measure these things as I tune by my ears, if I like it it stays , If I do not its good firewood for the campfire. If this sounds Unscientific for some of you, oh well its my system and my ears listening to it not yours. ( I do have REW but cant use it as I have no pre amp out, I will test with the new Krell KPS25sc unit) . This I can tell you the center image has really stabilized and the position of the instruments has dramatically improved. The corner slabs are not the biggest. The uppers are 6 inches wide., and the lowers are 3.5 inches wide. As stated I wasn't looking to change a lot. I just wanted them alcoves to be more even, with better reflection. 3 corner areas are always a bear to deal with.
This whole package has allowed me to move the CLS out a bit more and get a deeper sound stage and better overall sound. If you were to ask me what type of front wall I have? Id say, "a mildly diffusive acoustically reflective workable one" ! So far I will keep them but I am experimenting with some new Ideas too. Like multiple densities in different areas for the front panel . Multiple lawyers to represent me in my wifes insanity plea ! :banana:
