Acoustic Blanket for TV

@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.

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:

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.
