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.
