I am staring this thread as an organic continuation of the former Real Estate thread:

As any other threads at my site it will be a collection of thoughts and diaries of action related to my new listening room. The room is VERY interesting in my view that has a LOT of potential. Still I know it will take a lot of efforts to convert it into the musical interment tune to do what I need it to do. I think it will be my major audio afforest during the upcoming months. I did not measured anything in the room but I hope that with my techniques of  the “sane listening” I will be able to handle what the room m will throw to me.

The room has 4 in wall speaks and I have played the First movement of the Bruckner Seventh on it.

Meanwhile I am re-panting the room, renew the carper, organize the location of the CD, LP, equipment and the rest amendments.  In two days I will bring my playback in the game with the room will be officials start. I am curios how it goes…

I recognized that I have tired for the last week like hell. Do not ask me what I got tired from – I will not be able to say. That whole moving, packing, unpacking this was too exhausting… The good thing is that I go an interesting room as a result. That all crap about ownership of the house is not very much attracts me. In fact I am not sure if I like the whole idea but the room and the arrangements around the room in this specific house is very much pleases me. What I do not know at this point how the room sound.

I pretty much do not have playback setup for a month or even more. I kind of begin to miss it, not only Sound itself but the whole experience to invoke it at my will. Unfortunately the Sound as I understand it long away in my room…

The last nigh I decided to take it easy with unpacking and with working in my new house. All those tasks not going to run away from me. My pool was attacked by frogs that made those crazy noises during their breading period. I won that little war and I decided do not do anything else to the rest of the week and just to relax, this would imply to play some music. I did not connect the Macondo and Melquiades – it would be too complex and long to make them to work properly. I took a few monitors I had but they did not make it to me. Then I took Dunlavy SC3. The Dunlavys has an advantage that they are “as is” and they do not need anything else beside the power amps.  I dumped Dunlavy in the location what I think Macondo would be, connected the Dunlavy to Yamaha D2 and setup CD player (TL0 and Lavry 924).  I used Radio Shake or any other random cables throughout – there are no need to do anything better. I do not want to criticize Dunlavy – they have own problems but I know all of them and I thought it would give me some idea of what my new room is capable of. The sound all together was despicable, literally dreadful – but this did not particularly bother me, I was looking not for the sound itself but how it interacts with the room.  I moved speakers a bit, but nothing evolved – juts to get a generally acceptable presentation.  It was “somewhere there” and it was enough to stop “working”.

Then I took the biggest cigar I had, “laid” on my couch and give a good couple hours just to listen how it works all together. I was very interesting. The room has very-very appealing friendliness – it is just a pleasure to be in there. There is no acoustic treatment of any kind in the room, the playback sucks and the speakers are crap – still it was semi-enjoyable. With Dunlavys you can play only very specific music and only in a certain way and I decided to give it a full run. I played the whole Osvaldo Golijov’s St. Mark Passion. It is not exactly my type of music but it is insanely talented music and it is the only Passion that is possible to play on Dunlavys.  The room responded very interestingly. It was very different then what I am accustomed but in the way it was the same.  In this room it is possible to make HUGE presentation. The room has a god 35 feet width and all of it; even more might be used for presentation.  I think that by using properly set diffusers on the peripherals I will be able to curve that useable 35-40 feet. The room also has some superbly interesting back of the listening sit potentials. I have a good 10-15 feet behind the proposed listening spot where I am planning to put some reflections randomizers. It will be VERY interesting  to play with it what the sound will be at the right level.

Meanwhile I recognized that I do have a small wall section, approximately 50’ by 35-45’ that I would need to treat somehow. The problem with this section of the wall is that it needs to be very attractive treatment from a décor perspective. So, I am looking for some kind of “artistic” panel with good defusing characteristics. I have seen some of them here and there. Auralex does Shockwave AudioTiles that might be useful but I am looking for something sexier. Probably the large-grain of Tectum Acoustic Panels I might recognize as some king of Kandinsky’s paintings. I am juts partially kidding. This 50 by 40 part of the wall is very prominent in the room and I would like to have the diffuser to look attractive. The whole idea it to have living room not a dedicated listening room and it’s typical dental office ornamentation. So, if anyone knows a satin looking acoustic diffuser then point me out.

I know very well the critical near-field configuration and I have a lot of tricks under my belt how to make it to work.

Well, jessie, this "home move" turned to be a bigger discovery of myself in many ways then I thought. I am 42 and I lived all my live in city, I never had any usable backyard, garden or even plants. The only green things I ever have seen were inside of my Minestrone soup. Suddenly I was damped to suburban half acre land bordering a reservation – too much new things for me to deal with and I am discovering the things dally.

For instance the house has a nice pool, which is covered now. During the transition of the property no one care about maintaining of the pool cover and did not even knew that I need to do anything. As the result I got a colony of frogs mated in my pool’s cover. They scream like crazy at night and my bedroom is next to the pool.  It took for me a few days to recognize that they were frogs. Thanking about the super ignorance… I do not think I even have seen alive frogs before …

I spoke with former owners and they told me that I need to pick them with pool’ stick and send them to fly back to the forest. So, I did it for a couples days – was throwing the grog back to the conservation land. In few days I was driving home and I asked myself what the fuck I was doing? Frogs do not do anything wrong, they do what they shell do. They are nice creatures who peacefully eat insects and are looking for a comfy for themselves place to procreated. Suddenly an asshole with an awaken in him stupid feeling of lend ownership is throwing them out of his man-made swamp, probably killing them on lending. It is not that I care about the frogs too much but I was wondering where the hell this anger of protecting the idiotic pride of ownership had come to me? I did not like that feeling at all and I feel a shame for a few days. I dried out the pool cover and frogs done but the recognition of the fact that I was perhaps keeling those creatures and was not able to act more intelligent is something that did not make me happy. I would understand if they were republicans, but the frogs - they did not do anything bad….

Anyhow, the idea with the mean owls looks good.  I have a whole array of new sounds from outside that I need to get accustomed and to recognize. Still, generally the place look like very a quiet one, at least a number of my suburban friends who had visited me told me that it is quiet. The location of the listening room toward to the house helps to the quietness and I will make some extra measures to keep the noise from outside to a reasonable minimum.

Are the First reflection points for horns speakers are different from other type of speakers?

L= (2.86KPR/DMBmax) GT

Where:

K - Crossover point in kHz
P - Whole Dollars amount of dollars was pays for capacitor in the crossover
R - Elevation over the Sea Level where the horn installed 
D - Amount of month a person subscribes Stereophile magazine
M - The horns owner size of the shoe
Bmax – Number of the dependants in the horns owner claims in his 1040

diz1, I hope this will help.

You might use a plinth under each component, and several placed in the center of the room.

Then set up screw jacks spaced around under the center of the floor, under anything with a plinth and also under anything really heavy.

The jacks would in effect ground the twist-o-flex floor to something solid (the floor of the basement). 

Avoid jacking the floor into a preloaded convex parabola in an attempt to get it "tight".

It will over time requre more and more lift, as the floor structure will adapt and conform to the load, resulting in a sort of relaxed parabola. This is where a few plinths in the center would be of use; get the floor loaded, theoretically sagging a bit, then cram a few jacks up from underneath and bring things back into line.

The other way to do it is to tie the suspended floor to the floor of the basement; not just pushing up from below, but tying it down with rigid members fixed at both ends, locating the floor in space so that it cannot move up or down.
