@billybob @OO1 Thank you both for your valuable insights. I've done some research based on your suggestions:
1. On Amazon, the J-foot seems to be suitable only for TVs up to 70 inches.
2. I also came across a mention on BestBuy stating that the speaker has a maximum weight capacity of 70 lbs.
3. Lastly, I found another potential solution on Amazon that might address my needs.
I truly appreciate your assistance and guidance. Thanks again!
