Mitigating the Bubble

Today after many years of trials and tribulations I have mitigated a sonic aberration a horizontal phase anomaly in my center stage.  While the center image was always stable and outlined it seemed narrow and bubble like and I would need to shift my body angle to really lock in the image. This was obvious on many CDs and LPs .

I have many man made fixes that helped the situation but never a total cure. Some of these are now permanent fixtures on the ceiling in 2 different locations. I made my own acoustic panels filled with long hair sheep's wool and 3 Argent Room Lenses.  I have laminar flow lenses that focus and stabilize the image across the front stage. I have built and treated an acoustic fan that overcomes the  boundaries with in my room by reducing interference. I have loaded my speaker cabinets 3 times with new drivers and now an outboard crossover. This was after my Essence 30s speakers and my Dunlavy SC4s.  ..All my components are hard mounted and direct coupled to the floor...on rock solid racks and speaker stands, custom mono bloc amps each on their own stand. All of these devices and angles and positions made the image wider and more focused but I still had that little  bubble and shift before me. Always less annoying with each new device and tweak.

So, your probably saying to yourself hurry up and get to the end. The end finally arrived today after having applied a contact enhancer 7 days ago to just 6 RCA ends out of many connections in my system.  Today with a friend who has been here a hundred times sitting in the Chair playing the same music as usual he said there was a wider sweet spot. I despise that term but he said it and not me.What we both heard was a super stable center image that was a few feet wide and not just one. The bubble was gone. The head in the vise was gone.  Off came the straight jacket and helmet. What I have now in this space intime is a glorious fully extended soundstage with all the meat on the bones and the features of talking heads on a real live performance stage. 

I have probably used eight different contact enhancers over five decades but this one blows my mind. This product  Nano Flo is the ultimate in transparency.

A room with a view of the music. Supplied by the camera and commentary from OCD Mikey now on YouTube. STAR SOUND ENERGY ROOM ! - YouTube

The room surfaces are mechanically grounded to the floor and the hard surfaces are left to vibrate. All components are hard mounted to Sound Stage Audio Platforms and again left to vibrate on their own accord. The vibrations move down and out in a continuous fashion. Even the main breaker panel for this room is mounted to a Sound Stage Platform and direct-coupled to the wall.

No soft materials and no springy platforms to slow down the transfer of resonance energy. The corners are filled with steel shots. The size of the evenly rounded bearings was auditioned and chosen after being installed and played inside special cello endpins. The largest of the 3 sizes was chosen for optimum performance.

The greatest threat was overdamping the corners which we discovered those ill effects on sound during various applications in smaller room models.

For the new Caravelle speaker model, I chose two extremely linear drivers which allowed for a very simple and novel crossover build. The same speaker system is used in my own room but the crossovers are built outboard the enclosures for testing. Everything is direct-coupled and mechanically grounded through the speaker stands. All my components are placed using the same type of platforms and racks. I will need to remove the 2 speaker drivers clean off the old contact enhancer and apply the new Nano to the drivers and crossovers.

My room construction predates the Energy Room though I do use angles on the ceiling wall junctions in 2 places. The owner of this system has purchased NanoFlo but has not yet applied the product.

I hope the posted video will allow members to view and share construction methods some of which could be applied or adapted to their own audio rooms. We are currently reverse-engineering the Energy Room and hope to have retro-fitted surface mounted and portable products that mechanically function in anybody’s room. Let the Energy Flo. I am a member of Sound Stage Audio.

Like all Sound Stage products, these innovations were designed and tested by many people over the years of research and development. Tom

I will regret even suggesting it, but after looking at turntable porn today, I expect there is a better market for a nano-diamond lubricant for turntable bearings than may provide a real and measurable benefit, compared to a contact enhancer of dubious value.

To anyone considering it, this constitutes public disclosure and hence anyone trying to patent such a thing for this application after this date will be out of luck. I took a screen capture.

I have some of this lube in my LP 12 for over 2 years. Its nano diamond  lube in mineral oil works great. Tom

So you put in a slurry of diamond paste into a groove, and then plowed a diamond through that?

I suppose it should polish out the sound over time.

I emptied the bearing well of its black oil and replaced with a clear lubricant containing nano diamond lube. I stated this weeks ago in this thread. Tom
