Acoustic Blanket for TV

I put in a 50 inch TV near the left speaker in my office. The TV is against the side wall and the speakers are in the front wall. I am getting some reflections as I expected.

I was hoping to talk with these guys about getting some fabric to control the reflections.

However, I am tired of being sent to voicemail. I think it is time for another approach.

I have also contacted GIK Acoustics about this TV issue because I was at one time thinking about putting the TV in-between the speakers. They have not gotten back to me yet. However, I came to my senses on that and decided to move the TV to the side and not in-between the speakers. I was hoping to use a 40’ TV but that one is on it’s last legs so I had to use the bigger 50" TV.

I talked to a company about sound absorption blankets but they told me that their blankets would be too heavy for a TV.

What have people used to cover their TV’s to make nice with the acoustics? I am trying a folded quilt now and it works OK. However, my wife will eventually notice the missing quilt from the guest bedroom. So I wanted to get some suggestions before I spend some money on this problem.

Someone DM'ed me to suggest I try a furniture moving blanket. 

So I am now trying out a $20 moving blanket from HomeDepot. I have folded it a few times to gain additional absorption.  So far it sound good.

When I tired a wool blanket, the sound changed for the better.
Good old Army-Navy Surplus.

All the best,

A little bit of a surprise for me is that my Convolution DSP is now altered with this TV and blanket. I will need to redo the acoustic measurements to create new Convolution files. It actually seems like I need to turn of the DSP. However, I have already contacted the DSP expert I have do this for me and I will let him fix the sound. I am sure it will be better than turning it off.

One Owens Corning 703 panel 2'x3'x1" will do the job, cost little, and be light as a feather. You may want to cover it with some fabric. But it will be so light and easily moveable, you could also just hide it behind the TV and only hang it in front when listening to music. 

The thing about fabric, the outer layer has as big or bigger effect as the whole thing. Like nonoise got good results with a wool blanket the surface of which is rather porous. A thick moving quilt might seem better but the tight weave outer shell actually reflects more of the high frequencies we want to absorb. So keep this in mind if you do go with OC703 and select an open weave porous fabric similar to speaker grill cloth for your covering.
