Isolation of my chair, am I crazy???

Double stuffed, half and half. Mmmmm.

Clearly this one inch could have an effect, but it was more in the height of the sound stage. When I put my speakers on Aurios, Black Diamond pucks and tungsten balls the tweeter raised about a half an inch from original. Now my relative height is a half the other way. Of course none of that really matters because my ear height changes far more if I'm reclined vs upright. The sonics do not change with the chair relining so I doubt that is the issue.

If you think about it, live music and/or the recording environment is most likely solid with a concrete floor. My house has wood joists and wood floor. There certainly would a great deal more vibration in my house than the venue the recording was made in. The point being, my ears must be vibrating along with my bones as the chair vibrates. Wouldn't it make sense that this vibration distorts the shortest wave frequency?

It certainly is an intriguing question.

Marco my friend, you are one sick dude! Let me know where they hospitalized you, I'll be sure they send me there too, we tweaker must remain supportive of each other, and you clearly need my support.

I must report my latest findings, using ankle weights from a sports goods store work very well on the shoulder area and do have some marginal effect. The chair hass a greater effect, but it has twice fallen from the Aurios 1.2. I need to find someone who can bend some metal bars for me to create a holder for the chair legs. I can then have it bent to be just above the ground, thus keeping my ear and tweeter at the same height. I figure I could bolt the bar to the Aurios so it would work very safely. I could even screw the bar to the chair I suppose.

Anyway the entire concept is certainly food for thought as we spend another winter in front of our speakers. I hope this thread provokes other ideas, there does seem to be something behind this.

Geoffkait, I have indeed worked with various weights on different locations in my room. I have four 15 pound ½” thick steel plates with a rubber mat attached to the bottom and little rubber round feet. These were made for an audio dealer and I bought them from him. One is on a wood chest; this was quite a significant change in tonality of the room. One sits on my SCD-1, one is in a back corner on a shelf above the heat register and the last on leans against a large picture window treated with Margo dots, the window plate helped focus. I have quite a number of Walker disks (Brass and lead) on various pieces of furniture. As crazy as it sounds I have heard it on many occasions when friends come over and move the disks not realizing they were where they were for a purpose. Lastly I have my Great Grandfather’s tool box from his days as a gas company mechanic. It is made of ash and walnut with brass screws. It sits next to my racks, and needed to be set on rubber feet and weighted with Walker… I have not tried cones (too tipsy) and have not used any other “official” products. I do know all this stuff matters (good and bad), and a lot of the locations for furniture will affect the soundstage if it ends up in a frequency node that reacts with the furniture.

The point here is do not be afraid to try moving things around, even a candlestick on a table will effect the resonance of the table differently in different locations on the table. As I said with the weights, I also can hear it if someone moved an object in the room; my furniture is purposely not fully square with the room. Breaking up slap echo is very easy with the furniture 5 degrees skewed to the opposing walls.

Bob P. I have no earphones, but an interesting thought.

Honest1, I can not explain the Lazy Boy issue either. It would seem to be a big issue, but it really is not. As for the reflecting surface, your assumption was correct. The Sonics were cleaner with the weights under my outer shirt. (We ware layers here in Minnesota, so I did end up with the weights under cotton; I just skipped saying so knowing the fun people would have with my very serious post about a completely absurd topic. I like your assumptions. The same philosophy runs with cables. If the cable is changing the low end, we hear the relative differences in the opposite end (high frequency) and of course the bass is the frequencies most actively affecting my floor structure.

Marakanetz, sadly I think you’re serious and I resent the implied comment. I represent no one. I’m a hobbyist and have no plans to change that. I do however enjoy sharing my experiences, and I would appreciate not being under suspicion of…

For all the rest of you guys, I clearly deserve the flack. Enjoy, but please try and experiment (only when alone of course) As to the rubber room, I prefer Bubble Wrap!

Man with water on brain, thanks, and good to hear from you. I'll have to remember to write you, it's been awhile since we talked. Pure, I refer you to the following post from years back. http://forum.audiogon.com/cgi-bin/fr.pl?ymisc&1033743827&openmine&zzJadem6&4&5#Jadem6

Hi Tom, I tend to agree with you, but in my situation the chair must be overly resonant. I expect it is partially due to the wood joists and my seating location being closer to the mid span than the bearing. It sounds like this is not your issue. In my case, if my arms are resting on the arm rest, the vibration actually tends to distort the focus. It's very interesting how two experiences can be completely opposite, but in our case it might be predictable from the structure of our rooms. It's fun none the less to learn of others experiences.
