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.

@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.

@yyzsantabarbara  Must be very nice to have the CS3.7 speakers how you like them. Besides everything else, what a sweet looking pair of speakers.

@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.

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.

These fabrics and curtain construction were tested at independent acoustical labs and are rated at .65 NRC (this means 65% of the sound that comes in contact with the curtain will be absorbed in the fabric and curtain folds and not reflected back into the room, significantly reducing echo and reverb.

Your Quiet Curtain, 48” wide x 30” high, unlined, costs $275.00.

The panel I got seems like the better solution for the TV. However, I have 2 windows that may benefit from these curtains.

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.


One of these:


6A Alpha Series Rectangle with 2D Scattering @ $198.00

4A Alpha Series Bass Trap Diffusor/Absorber (Rectangle) with 2D Scattering @ $138.00
