Thanks guys. I have the benefit that I do not care what it looks like in my office. Trying the Owen Corning or a Wool blanket is cheaper than redoing my DSP. So I will give that a try first and see if that works with my existing Convolution files.
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.

I just ordered an Owen Corning panel from these guys, 48" x 24" x 1". It has
Guilford of Maine acoustic fabric. https://www.acoustimac.com/ |
I thought about this a little more last night and decided to dump the TV to the garage and make the sound as good as before the TV went in. The TV I have in the garage is on it's last legs and the office TV will go there. @mijostyn Not sure about the wall being the same as the TV with respect to reflections because of what I hear with the TV in-between the speakers. Fatigue or headache is easy to identify. Not like bigger soundstage or blacker background. |
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. |
The guy at Acoustic Curtains got back to me today. https://www.acoustic-curtains.com/curtains/acoustic-curtains/ Our custom made sound absorbing curtains are pleated with 2x fullness using fabric Destiny, Nova Suede or Visa Velvet. Hooks are installed on the back side and the curtain comes ready to hang. The panel I got seems like the better solution for the TV. However, I have 2 windows that may benefit from these curtains. |
@jeter You are correct if I wanted to be rational. However, I now have 2 sources of amplification in my setup. I made the mistake of listening to the RAAL S1a ’earphones’ and have now been on a mission to find the perfect amp for it. The KRELL K-300i integrated is the chosen amp for the SR1a. My Thiel CS3.7 will be driven by an all Benchmark stack. I could not part with BM stack to have the KRELL drive both the CS3.7 and the SR1a. I have an amp interface switch from RAAL to make that possible. I would also need to put my source components in-between the speakers if I used the KRELL. That is a non-starter. I will be watching the TV (my Leafs and Jays) on the TV using the SR1a earphones. It is almost the same experience as with the CS3.7 speakers. Maybe better because I can watch late at night without disturbing anyone. I did try a broken down 40’ TV in-between the speakers (resting on the floor) last week and it was a nightmare. The side positioning with the moving blanket over the TV is what I am listening to as I type this. It is just a tiny bit fatiguing and the sound overall is a little messed up. That is the reason to try the panel I linked above. If all fails I put the TV back in the garage with my exercise bike. |
@jetter The Thiel CS3.7 have been my second favorite speaker of all-time. There is something about the sound that just felt right to me. The KEF Blade is my fav. I never had the space for it in the past nor now, but I was able to use DSP with ROON Convolution files to make the sound fit perfectly into the room. Adding this TV has messed that up a bit and I have contacted the sound engineer who created the Convolution files to redo them once I settle on the TV issue. I bought the Thiel CS3.7 in Oct 2020 from a local-ish seller. The speaker turned out to be in very bad shape. One of the COAX drivers was wired both out of phase and the mid was connected to the hi and the hi to the mid, a catastrophic outcome for the COAX. So I ended up buying 2 brand new COAX’S from the former Thiel Service Tech out in Kentucky. Over the course of about 2 months, he helped me remotely rebuild the speaker. - I had to re-thread a screw in the ’good’ COAX since the speaker was no longer air sealed - fix a broken connection in the crossover - check all the wiring with a meter to verify proper current levels - paint the speaker black (due to my screw up) The end result is a speaker that sounds brand new and has new COAX drivers and 2 year old bass drivers. So I think this speaker will outlast me, at least in my office. Initially I was thinking of using the Yamaha NS5000 in the office but the Thiel had a nostalgic connection for me and I could not be happier with the result. When I was re-building it I was worried about the end result it all turned out well. |
Another option this time from GIK Acoustics that was recommended to me by the guy who did my GIK panels. If the problem is only the TV I have had success with using Alphas as they diffuse and absorb. The thicker the better. |
An Update: I received the https://www.acoustimac.com/ panel that was previously mentioned. I am impressed at the ability of this panel to absorb the sound and make the TV doable in-between the speakers. I also have the moving blanket over the TV and then the panel resting against the blanket. So a double shot of solutions. However, there is still a bit of hardness on the sound that was not there before the TV went in-between the speakers. I think I said I was going to keep the TV to the side of where I sit. It looks like that is what I will do. I wanted to see if the in-between the speakers setup would work. Prior to trying the blanket and the panel the sound was awful with the TV in the middle. With these 2 I feel it has improved about 90% but that is not good enough. |
