Doctor's Orders-Part Two-The New Listening Room Of Steve Williams

The fabric is a very heavy one designed for commercial applications and rated for noise reduction. This plus the fact that the drapes had an inverted pleat in a ratio of 2.5:1. The drapes also had a backing and in between the drape and the backing there is a material called Lumitex which basically turned the drapes into one large bass trap

LUMITEXTM:
The first and main acoustic treatment within the room was to include LumitexTM for the treatment of the mid and high frequencies. LumitexTM is a nonwoven Class A fire rated fabric. This thin (3.5 oz./sq. ft.) fabric creates a fairly even absorption across the speech frequencies and has a far better absorption in the lower frequency than foam or high density fiberglass. The absorbency of the fabric varies as does the airspace between it and the boundary of the room. For Steve Williams’ listening room the LumitexTM was placed between an open wave curtain fabric and a liner. The main purpose of the LumitexTM was to provide absorption. Since the LumitexTM curtain so perfectly addresses mid and high frequencies, it allowed for an easy focus and treatment of bass
??frequencies.
??????????This graph is slightly deceptive, since it does not do service to acoustic phenomena that is created by the Lumitex in the fold of the curtain. That is, the ultimate beauty of the curtain with LumitexTM as an inner septum is that the curtain’s texture and folds (that also provided a varying space from the boundary of the wall to the LumitexTM), resulted in an organic diffusion. This organic diffusion was part of the acoustic wave response to the boundaries in a manner that allowed the wave interaction be more in line with a room of larger dimensions.

Congratulations Steve. Nice, cozy, and neat. Great thing is, it sounds great. I can imagine the effort and strain you went through in moving houses and rebuilding and redesigning a listening room so much different from the previous one. I had done that and I might do that again if my plan materializes. Will definitely make your place a destination if I visit the San Diego area.

The History

Most of you are aware by now that I moved back to Southern California in July last year after a 20 year hiatus in the SF Bay Area. It was there that I built my "dream" sound room. That room measured 18' W x 31' L x 9-12' H (sloped ceiling which was 9 feet high at the window and 12 feet high at the inner wall). My system then consisted of both two channel set up as well as a home theater with an 11' screen.

Here is a link to my prior set up

http://www.whatsbestforum.com/showt...-Of-Steve-Williams&p=3412&viewfull=1#post3412

My wife and I moved to the SF Bay Area in 1993 but with the resolve that we would always move home to Southern California. Just about this time last year our youngest daughter was graduating from the University of Boulder. It was then that not only were we aware of our empty nest but also that a few homes in our neighborhood were listed for sale. It was then that my wife suggested we consider listing our home. Well after 20 years in a home that I had built it was a difficult thought for me to consider as I loved our home and it was a source of wonderful memories. As a result, even though I always wanted to return to Southern California I was so attached to our home that I agreed to list the house for sale BUT only at a price that I felt it was worth rather than being dictated by the comps in our area (as I was torn about moving). As a result I listed the house at $200K over any comparable sold home in our area. We left for Boulder on a Thursday. The house was listed on the MLS the following day. The next day I was called by the broker to tell me that 3 people wanted to see the house on the Monday when I was back home (3 days after I listed the house). That next afternoon 3 different families toured the house and that evening I had 2 offers on my house, one which was $50K shy of my list price and a second which was not only a full list offer but so also a 30 day escrow. My wife and I took a deep breath as we suddenly realized that my wildest dream had become reality and that we were moving in 30 days. We now had to find a home to buy. We could have rented but I was opposed to this because I hate moving. Even if it is to the house next door it is still moving so we made a few day trip back to South Orange County and as luck would have it we found a really nice home of about the same size as the one we were selling. Both houses are ~4600 square feet but the new home did not have a dedicated room that I could convert to a new listening room. We moved in last July 6th and for 8-9 months my entire system sat in crates in one of our garages. Once settled in the house I started worrying because I coud see no option as to where to put this room. Believe it or not we considered moving but we really liked our new home. We live in the master planned community of Coto De Caza where my home sits on the 5th fairway of the south golf course. Even though both houses were about the same size the lot sizes were much different with that of my newer home sitting on a smaller sized lot. This pretty much excluded building "onto" the house as the rear yard was all landscaped with a pool. We have 3 garages and for a brief while I considered building the room into one of these garages but after working with an architect this just wasn't feasible. I must admit I was getting depressed about the distinct possibility, that after over 50 years in this hobby and always with a dedicated sound room that this was just not going to come to fruition for this one last "hurrah".

Finally after much thought, as well as my wife acquiescing to the idea I soon came to realize that if any room is possible in my house it would have to be "built into" rather than "built onto". The ONLY possibility was to build my room over our living room. Our house has a very open design and our living room has a 20 foot high ceiling. After much agonizing and with my wife's "OK" I decided to build above the living room which measured 20' L x 15'W x 20'H. Essentially what I was going to do was to build a new ceiling 9' high. This then would create an identical sized sound room above (20'L x 15' x 9'). I hired an architect to draw up the plans and with the help of a structural engineer devised a new ceiling (subfloor) which would be able to sustain a load of 1500 lbs per square foot. I did this because of the heavy weight of all of my gear andI promised my wife that it wouldn't fall through the floor into the living room below. By building "in" rather than building "on" I didn't have to make any structural changes to the roof of my house. Plans were drawn up and approved by the county in early January after 6 weeks of waiting. In the interim this is when all of the mind games started as to whether this room with the constraints on size would be overwhelmed by the shear size of my speakers (Wilson X2 Series ll). I had extensive discussions with many of my audiophile friends as to whether my plan would result in the room being overpowered. All of my audiophile friends with whom I consulted told me I was out of my mind, crazy as well as other expletives. They felt it just simply would not work.Needless to say I became quite depressed because they were all telling me that I needed to consider downsizing my speakers and find ones that would fit the room better. Suddenly I was considering trading for the new Wilson Alexia which I love BUT if I were to do that I would also have to consider buying a new preamp and amp as there was no question in my mind that mine would have difficulty driving the Alexia as they are tubes and only 32 wpc (Lamm ML3 Signature/LL1 Signature amp and preamp). In other words there was a distinct possibility that if I build this room I would need to revamp my entire system. I wasn't anxious to do this as I love the sound and didn't want to consider giving up that huge soundstage thrown by the X2's. As a result I began doing further research. I remember when the X2 Series l was released it was front ported rather than rear ported and I remember comments made by Wilson Audio that it was designed as such to take into consideration the small rooms in which the speaker would be used in Asia. I had conversations with the entire Wilson team either by phone, email or in person at RMAF. I spoke to Debbie Wilson, her brother Darryl and father Dave as well as Trent, John and Jeron at Wilson Audio. They consulted with their engineers as to the possible shortcomings of using the X2 in a room of this size. All of them stated that using the speaker in a room of this size was indeed possible. They even went on to say that Fremer's room with his XLF's is smaller than mine and his sounded fine. They also added that working with an acoustician would be recommended. Had it not been with the encouragement of the team at Wilson Audio I probably would have abandoned my quest. Dave also said that because of the aspherical design of the upper modules it would be easier to fine tune the X2 in the room rather than with the Alexia

I did a lengthy search of acousticians as there are excellent ones who are members here at WBF. After a 4 week search I realized that if I were to do this any sound improvements put into the room could not be like my last room which was much larger. As a result every precious inch became valuable and I just couldn't spare any extra which would take away from the size of the room. My search brought me to the acoustician I finally hired. Bonnie Schnitta is a Phd in acoustics, electrical engineering and mathematics. It was with this knowledge and while working with the DOD and underwater sound mapping that she wrote a program which provides for mathematical mapping of a room's sound response. When she left the DOD, Bonnie took with her that part of the program which was hers and launched her business Soundsense based in New York city
www.soundsense.com

Her proprietary acoustical things are made through her company

www.noiseout.com

Dr. Bonnie Schnitta is the founder and president of NoiseOut as well as SoundSense, LLC – an acoustic consulting company she formed in 1981. Over the last three decades, Dr. Schnitta has headed hundreds of noise abatement and acoustic management construction projects in homes, churches, synagogues, theaters and recording studios. A CEDIA member since 2001, Dr. Schnitta holds a bachelor's degree in Mathematics from Purdue University, a bachelor's and master's degree in Mechanical Engineering and an interdepartmental Ph.D in Math, Computer Science and Electrical Engineering with a special emphasis in signal processing. She began her career working with ship designers, controlling the acoustics of oceangoing tankers. Although she originally focused on commercial projects, assisting restaurants and auditoriums with noise problems, Dr. Schnitta has branched out into the residential market. “I was just heartbroken to discover that homes were being designed with so little regard for acoustics,” she says.
Dr. Schnitta holds several patents, including an acoustical plumbing trap system, a method for analyzing activity in a signal, and the Paradise Effect™, a proprietary algorithm for the creation of an acoustically-correct and soothing environment. Dr. Schnitta has authored a number of articles on such topics as signal processing and acoustics management.

Bonnie made a site visit to my house in December, took measurements and then upon her return to NYC, plugged all the data in and called me a few days later stating that not only would things work but the room would sound very good. I guess this is what I wanted to hear. Sort of like asking an orthodontist if you need braces :)

The next post will contain all of the ideas and sound treatments added to the room as well as aesthetic treatments. I will follow that post with a synopsis of treatments that Bonnie has provided to me in a write up and I will follow this with several photos of the build out and the finished product

The room was finished end of March and I have been fine tuning the speaker placement, taking measurements and finally adding a pair of JLAudio F113 Fathom subs. I did have a pair of Gotham subs in my last room but I sold these as they for sure were just too much for the room

Hi Steve:

I very much look forward to hearing and seeing the system for myself. Outstanding post and excellent detail...no stone left unturned
in the process.

As Andre says I want to be certain that this is more than just expectation bias or another story of the Emperor's New Clothes. To that extent I have asked Andre to come by next weekend for a listen for several reasons

1. I find him to be honest and ethical and therefore I believe he will tell me if there are shortcomings

2. He lives close and we have never met

3. He commented several months ago about how he dislikes big speakers because the mouths of the singers or size of people is over exaggerated in the sound stage. IMO this happens with poor set up. I am hoping therefore that if he feels the same I will have to tweak my set up. If he likes it, then I have convinced him

Stay tuned

Hey Steve:

I very much look forward to it.

One clarification, I actually don't dislike big speakers. I have heard large, multi way speakers create exaggerated image sizes, but part
of that is just physics.

I can tell you having heard the XLF's at a dealer last month for several hours, I was blown away.

Sure, the imaging was very tall and very wide, but this is a matter of suspending disbelief and enjoying
the presentation.

Room looks great, Steve:). I'm sure it sounds that way too. I'm living with a small dedicated room as well; in some ways, I believe that a small room can be preferable to a large room. IMO, a small room can give you more intimacy of performance. What I mean by that is a better ability to hear the little details that allow you to be fooled into thinking you are in the presence of a 'live' performer.
However, I do believe that in a small room, room acoustic treatments may be of even greater importance than in a large room. I know in my room, they made a major contribution.

BTW, what day are you going to be at Newport?

It was truly an experience. Carl are you coming to THE Show in Newport this year.

I have already placed my spousal unit on notice that I will be going to RMAF this year, and reminded her that she agreed to that last year, so that will be my big audio trip this year. May go down the coast, too, in the fall, but don't know specifics yet.

I will be in Newport Friday, Saturday and possibly Sunday.

My buddy Marty will be in town with me as well
