Off axis cloud placement


I am currently in the process of fine tuning my room which is 10wx25Lx10H.  I have GIK bass traps in all 4 corners and GIK absorption panels at first reflection. I have also treated the room with Synergistic research HFT's and a FEQ.  I have noticed that on certain recordings, the high end is a little bright. My dealer has also noted that the room was a little "hot".   I was thinking of adding clouds to help with this.  The sound is otherwise awesome.  My floor is wood with a large rug covering 85% of the area.  So now the problem.  The likely area of first reflection is occupied by a fan.  I am making two 4X6 ft clouds using Owen Corning 703 fiber panels.  Will they be helpful if placed just in front of the fan and just behind the first reflection point?  This will place one in the front third above the amps, and one over the listening position in the back third. Or is this just wishful thinking and a waste of time?

@orthomead - you should be able to get the vinyl from any place that prints commercial signs in your area

But before spending lots of money on this, execute a proof of concept

  • go to the Dollar store and buy a plastic table cloth (cost about $5)
  • tape it in place using masking tape - but use a doube layer
  • If it solves your problem then you can look for a more elegant solution

You could opt something like this as a more permanent solution - then it would blend with the wall covering

Hope that helps - Steve

 

 

Do what I did and get rid of the ceiling fan altogether ! I put 3 GIK 4 " x 6" using their ceiling brackets at 8 inchs apart and will tell you it's worth it. I had a nice ceiling fan up there but never used it , so taking it done was the best idea in a long time. You can also install a duplex in the ceiling box and put an led light strip in the center panel and have a great ceiling effect what ever color your mood wants. If you still want air circulation in the room get an air purifier !

@williewonka What a simply elegant test.  I will definitely try that.  It may take some time due to work and social commitments-don't usually get home until after 7 p.m.  I will let you know.  Just curious-ifI don't see an improvement is that a plus or minus for cloud treatment?  Also, I suspect you may be right about my complaint not being a reflection problem, btw.  One consistently irritating song that partially prompted this post was Don Henley's "The Boys of Summer", the high end on the horn section, in particular.  I placed a similar post on another thread and one response from another poster with a well treated room was that same passage was uncomfortable for him as well.  It may be a recording issue.  To be clear, this is a problem on only approximately 10-15% of my vinyl, but its always high frequency passages that are involved.

@jdub39 Can't really take the fan out, unfortunately.  With the tubes and south Florida heat, the room can get uncomfortable.  Had the AC guys out and they didn't think that adding  additional ductwork would help. The thermostat controlling this area is in a different room.  I can crank it down, but "hell freezes over" in other areas, so the fan is here to stay for better or worse.  I do suspect I get some diffusion from its odd shape though.  Thanks for the thought

@orthomead re:

To be clear, this is a problem on only approximately 10-15% of my vinyl,

OK this may be something very different

  • it could be an issue with cartridge/arm compatibility or alignment?
  • or even tracking force?

I might try a couple of different VTA adjustments first and make sure the other parameters are setup correctly

  • is the stylus worn???

Assuming everything with the cartridge/arm is correct...

  • If you have a digital streaming source, try the same track on that first to see if the problem exists

FYI - If you do not hear any improvement with the table cloth in place, then that is not your problem

  • and you have only spent $5 to determine that👍😀

@williewonka Have adjusted VTA both up and down from neutral.  Lowering VTA didn't fix it and made low end a little boomy.  Pretty sure I have it optimized.  Tracking force is per manufacturer, and I adjusted it with VTA changes.  I do have a digital source and will try that next.  Stylus has been meticulously cared for-Van den Hul Crimson stradivarius .  Steve, thank you for your interest in my "problem" which may be a recording issue.  That is easy to sort out.  Now just need to find the disc...
